Description

Regulation arrangement and procedure for auto-

automatic calibration of the zero error of the temperature control parameters of a gas turbine The invention relates to control arrangements of gas turbines, it relates in particular on an improved control arrangement and a method for control the flow of fuel flowing to a gas turbine to the temperature of the gas turbine to regulate.

The current high demand for gas turbine power generation systems for use at high peak loads makes it reliable and economical Operation of these power generation systems is important for the user. This has to be great Part of its cause is that these Stremorgeneratinganlagen eftmals in remote Areas are grounded and run unmanned. To achieve greater reliability and The regulation must ensure more economical operation of the turbines the turbine temperature. A remote control or remote control is sometimes used above Telemetry connections provided.

In order to ensure a higher reliability of the turbine, the Regulation of the turbine temperature can be very precise.

However, it is more important that the arrangement that regulates the temperature, must be more available for the turbine. I.e. the arrangement should facilitate the operation of the Continue turbine even if there is any turbine control function or condition is disturbed by a non-catastrophic incident. A plant that can run continues even with certain malfunctions, is referred to as "fail-soft", whereas a system is referred to as fail-safe if it switches off at any fault.

Traditionally, the operating temperature of a gas turbine is either by regulating the combustion temperature or the exhaust or exhaust gas temperature of the turbine. Regardless of the temperature to be controlled, a large number of thermocouples are used or other temperature sensing devices are used to sense the turbine temperature.

Most turbines have a variety of thermocouples on arranged in different places of the turbine exhaust chamber to measure the exhaust gas temperature to measure, and the temperature signals generated by the thermocouples averaged to calculate a value proportional to the mean exhaust gas temperature is.

In known systems, this averaging was carried out using electronic analog elements made, which are interconnected as a temperature control arrangement, ur to regulate the mean exhaust gas temperature at a given value.

Within temperature control arrangements, analog elements, independently, whether it is pure analog elements or a combination of digital and analog elements there are several problems: 1. A reference temperature setpoint is set in the controllers or base temperature, usually an analog reference voltage, for comparison with the average exhaust temperature used to generate a fuel control signal to regulate the fuel flow to the tubin @, and thus the operating temperature, derive. It is known that these analog reference voltages drift with respect to Time and / or temperature are subject and therefore to inaccuracies in the temperature control to lead.

2. Wiring the thermocouples among themselves to make an averaged Receiving a temperature signal is an undesirable situation. For example, if a Thermocouple by emitting an output signal that is less than the specified output signal damaged (e.g. short circuit, incorrect display of a cold point in the exhaust chamber). so the averaged exhaust gas temperature incorrectly becomes a lower exhaust gas temperature Show. As a result, the control sequence of the system control is an increase in the Cause the exhaust gas temperature to be higher than the specified value. Mine like that Increases in temperature can seriously affect the life of the turbine.

3. By wiring the thermocouples to one another, it is difficult to electronically determine the validity or reliability of each thermocouple to be determined during operation. No information is then available around likely abnormal turbine combustion problems, damaged thermocouples or perceive bad wiring.

4. Furthermore, it is difficult to create a "soft" turbine temperature control or to realize tax system without significant oversized costs incurred by the important attachment of redundant analog temperature controllers and components for peeling out the possible combustion problems arise.

5. By analog / digital and digital / analog converter circuits Tolerance and drift errors from digital controllers introduced into the temperature calculation. Forner can do digital calculations by rounding up and truncating numbers Errors or inaccuracies can be introduced into the temperature calculation.

6. Additional inaccuracies are also due to the tele-tolerances the summing resistances at the inputs of the amplifier in the temperature calculation introduced. Further inaccuracies are introduced by various buffer amplifiers, which are used to shape the input and output signals of the Accept rules.

All of the inaccuracies mentioned all contribute to disagreement between the specified reference temperature setpoint and the calculated mean Turbine exhaust temperature at. This difference accordingly leads to an imprecise one Regulation of the turbine temperature.

The difference between the reference temperature setpoint and the calculated one or certain mean turbine temperature can be used in terms of the operation of the Total system can be harmful. For example, a loss of accuracy of some Degree of turbine temperature both the praise duration and the economy affect the fuel supply. Iodine of these impairments can cause it contribute to the fact that the user or children accept the o less.

It is therefore desirable to have a set of rules and a method for to provide precise control of the operating temperature of a gas turbine, the the life of the turbine is increased and the fuel operating core of the turbine is increased decreased.

According to the invention, the aforementioned disadvantages are eliminated by that a turbine temperature control system is created, which is an economical Has a "soft foal" and operationally reliable structure and is capable of electrical Tolerance and drift foils in a fuel control signal to control the fuel flow towards the turbine, and thus in the temperature of the turbine.

According to one embodiment of the present invention, the controller the temperature of a gas turbine by a digital computer with stored Program or a programmable controller is carried out, which reads and Storage of the temperature readings or values heard by the signals of the Temperature sensors are supplied in the turbine. The computer program exists from commands which, when executed by the computer, result in a series of Steps methodically the validity or reliability of each sensor condition, such as a Short circuit or an open connection, determine the computer program calculates the value of a trim signal (trim signal) or fuel control signal that is used for Regulation of the fuel flow into the turbine, and thus to regulate the operating temperature the turbine is used.

In one case, the calibration signal assumes a value that depends on the Difference in size of a specific, desired operating temperature of the turbine proportional reference temperature and a calculated value is derived, where the calculated value is a function of the operating temperature of the turbine, obtained by averaging the values of the temperature readings.

The reference temperature can be stored in the computer or from a external voltage source are fed to the computer.

In a second case, the adjustment signal is caused to be a predetermined one Assume a value that indicates an unreliable asset if an oversized one Number of sensor conditions were found to be invalid. In this case it will the calibration signal is downgraded to a value that is ineffective for fuel control. The calibration signal is set at slow speed by a fine-tuning constant set when there is a difference between the reference temperature and the mean Turbine temperature exists to eliminate the difference between them to any electrical tolerance or drift errors in the system to compensate for this difference cause. Because the difference between the reference temperature and the mean temperature at the value or within a small dead band range lies, the accuracy of the control of the turbine temperature is improved.

Analog back-up protection devices are included in the annex to operate the turbine at a reduced temperature determined by a turbine reference safety temperature in case of a malfunction of the computer, possible combustion problems of the turbine, or when the turbine is triggered, when the turbine is switched off, or when one is detected serious combustion or instrumentation problem is specified. The analog Reserve protection devices are temperature signals from selected turbine sensors fed. The analog devices generate a signal with an average value, its Size lies between the values of special temperature signals, whereby this size is approximately equal to the mean exhaust gas temperature of the turbine. This signal with average value is used by the computer when calculating the calibration signal. Further, the intermediate value signal becomes the reference safety temperature signal and added to the trim signal to produce a temperature fuel control signal of to the plant equipment, u regulate the fuel flow for the turbine into ##.

The analog reserve protection devices contain former a device, to shut down the turbine in the event that a predetermined number of with the sensors connected to analog devices is disturbed or an invalid condition shows, or if the temperature of the turbine is too high. This feature of the present Invention represents a fail safe operation to the turbine to protect in the event that the sensor instrumentation becomes unreliable or the turbine overheats.

According to a second embodiment of the invention, an analog controller monitors continuously the signals or temperature readings generated by the turbine sensors will. Devices in the analog controller average and conduct the temperature readings a value proportional to the actual turbine temperature. The real one Turbine temperature value is algebraically combined with a reference signal, which is proportional to a desired turbine temperature to provide a correction signal derive, which is slowly adjusted by a fine-tuning constant. The correction signal is combined with a signal proportional to the desired turbine temperature is to generate said alignment signal which the analog backup protection devices is fed.

According to a further feature of the invention, the analog controller monitors continuously the signals or temperature readings from the turbine sensors be generated.

My first device in the controller compares these L.swerte with given ones Reference limits or limit values and rejects those read values as invalid sensors that are not within the specified limits. The non-rejected reading values are averaged to determine the mean turbine temperature.

The second direction in the controller continuously monitors the sensor readings and compare each of these readings with a variable reference signal that has a value proportional to the algebraic sum of the mean turbine temperature and a predetermined reference value which is a maximum temperature deviation for each temperature reading. Any temperature reading that is above the variable reference value is rejected, since they are from one Sensor, which senses a possible combustion problem of the turbine. Provided a predetermined number of signals is rejected, the partial temperature fuel control signal becomes brought to the value zero.

whereby the fuel supply to the turbine is stopped.

The total number of unrejected temperature readings is averaged, to derive a value proportional to the actual turbine temperature is, which is also referred to as the actual value of the turbine temperature. The actual value of the According to one embodiment of the invention, turbine temperature is algebraically with combined with a reference value proportional to a desired turbine temperature is to said fuel control signal to control the fuel flow in to derive the turbine. According to a second modification of this embodiment Include the analog reserve protection devices in the system. At this the latter modification, the opposite signal with a medium value becomes algebraic combined with the actual value of the turbine temperature to derive the calibration signal and to supply the analog backup protection devices. The analog backup protection devices deliver a temperature fuel control signal to the turbine as previously described became.

According to a third embodiment of the invention, a static scan digital controller continuously detects the temperature sensors, performs an analog / digital conversion of each temperature reading from the sensors and calculates the value of the temperature fuel control signal to regulate the turbine, this calculation based on the number of non-rejected Sensor readings is established.

In the last-mentioned embodiment, there are devices in the controller provided to enable the calculation of the mean turbine temperature, the based solely on the values of the unrejected temperature readings.

A memory device receives a value corresponding to the individual temperature readings is proportional. If a temperature reading is rejected, a zero will be displayed for this reading is saved. Any valid or unrejected temperature reading is subtracted from a special limit that is proportional to the algebraic Is the sum of the mean turbine temperature and a specified reference value, which indicates the maximum deviation of the mean temperature.

If a subtraction results in a condition that the limit value is exceeded, if this temperature reading is rejected as a possible turbine combustion problem, sensed by the sensor generating this temperature reading. The values of all non-settled readings are again totaled, and the value the actual average turbine temperature is calculated using the number non-approved and good temperature readings and the sum of these readings is calculated.

According to a modification of the last-mentioned embodiment, the Value of the temperature fuel control signal calculated by the fact that the actual mean temperature is subtracted from a base reference value that is proportional is the desired operating temperature of the turbine.

In this embodiment the analog backup protectors are also available in the complex. The temperature fuel control signal that goes to Turbine is running out through the analog backup protection devices generated by the trim signal, the medium value signal and the analog Reference temperature safety signal has been combined as previously described.

In Fig. 1, a gas turbine 10 is in a simplified representation a wool is shown comprising a compressor 12, a combustion chamber 14 and a turbine 16, which is connected to a load 18 and drives it. The through the Air escaping from the compressor inlet 20 supports the combustion of the fuel, which is injected through a nozzle 22. The heated exhaust gases enter a turbine outlet 24 and flow to distributed temperature sensors or thermocouples 26 over, with the thermocouples 26 generating signals to set the exhaust gas temperature in an exhaust chamber 28 to measure. A variable fuel feed pump driven by a shaft 30 delivers fuel to nozzle 22 at a rate that depends on both the rotational speed the shaft of the gas turbine 10 and depends on the setting of the pump stroke, the is determined by a fuel control servo device 32, which is mechanically connected to the pump 30 is connected. Fuel control servo 32 details do not form part of the subject matter of the invention, since this servo device is everyone may contain any servomechanism that controls the stroke adjustment of the pump brings into a position that corresponds to an electrical actuating or fuel control signal (VCE), with many facilities suitable for this use on the There are also the gas turbines with liquid or gaseous fuels can be operated, a gas valve adjusting device can be used to regulate the fuel flow flowing into the combustion chamber can be used. The term "fuel control signal" is commonly used for a signal indicating the flow of fuel to the turbine regulates regardless of the type of fuel used.

The fuel control signal VCE is a single-valued electrical signal, through a low value gate 34 of the fuel control Servo device 32 is supplied. The VCE signal always has a value that corresponds to an input signal is given from a plurality of input signals applied to the gate 34, wherein Each of these input signals over a specific phase of the operation of the gas turbine Should have priority. The structure and working principles of the low-value gate 34 are detailed in U.S. Patent 3,520,133 entitled "Gas Turbine Control System" described.

Referring to Figure 1, there are three inputs to the low gate 34. One of these signals is a temperature fuel control signal TFC, which is from a analog temperature reserve protection device 36 is supplied, which is part of the Invention represents. The other two signals are from a speed / load control 38 and a start control 40 supplied. During the basic operation of the low value gate 34 gives whose output signal VCE inner represents the value of the smallest input signal, that rests against the gate. That is, the fuel control signal (VCE) cannot be higher as the lowest control signal that is fed to gate 34. In the present Embodiment provide the speed / load control 38 and the start control 40 does not form part of the invention. They are only shown in FIG analog temperature backup protectors 36 for clarity and convenience Completeness of the disclosure in the context of an overall turbine control to show. The speed / load control 38 and the take-off control 40 can be free-standing units that receive input signals from various sensors in the Turbine or they can get calculated signals from a programmable Controller or computer 42 received via conductors 44 and 46 when the arrangement is under Computer control runs.

The controller 42 can be any of the many known process computers, e.g. a General Electric 4010 or 4020 process computer, or a programmable one Regulators exist such as that manufactured by the General Electric Company Logic controller named "Directo-Matic". The latter regulator is suitable ideal for incorporation into the preferred embodiment of the invention, and details the operation of this regulator are filed in U.S. Patent No. 3,969,722 on July 3, 1974.

The controller 42 is preferably of industrial design and includes Analog / digital converter devices for converting applied analog input signals into digital values for storage in the controller's memory, and it has digital / analog converter facilities, to convert the digital values into analog signals when the signals enter the memory of the controller as output signals. As the process of converting digital and analog data are known, the circuits are used to perform this Features not shown. Analog input signals ATCX 1 to ATCX 12 and AOTA-AOTC are read as temperature values from the turbine sensors 26 via a plurality of conductors 48 supplied to the digital controller. These signals have values that indicate the temperature of the Mark the exhaust chamber 28. Should a temperature sensor 26 also be damaged or be disturbed, e.g. due to an interruption or a short circuit, this delivers there is no signal on the line corresponding to the faulty sensor valid "condition to the controller and indicates that the sensor is faulty.

It should be noted that a variety of special sensor signals, such as by the three signals AOTA, AOTB and AOTC is shown as input signals via the Conductor 50 are fed to the analog temperature reserve protection devices 36.

Although these three temperature signals in the total averaging of the Contribute to the turbine temperature, the sensors of these signals are also used as backup protection to increase the reliability of the temperature control arrangement according to the invention used. The purpose of these latter temperature signals will be related with the description of the analog temperature backup protection device 36 more obvious.

The analog backup protectors 36 receive a temperature trim signal or - control signal BTMTEM on conductor 52 from the programmable digital controller 42. As shown by the dashed continuation of conductor 52, BTMTEM can optionally be used as a temperature fuel control signal TFC to the input of the low value gate 34 are supplied when the analog reserve protection devices 36 in the standard arrangement are not provided.

The mentioned signal with medium value. through the analog backup protection devices is generated is shown on conductor 54 as a signal ATXD dem Regulator 42 supplied. When the analog reserve protection devices in the rule arrangement are provided, the value of the ATXD signal is between the values of the three backup protection sensor input signals AOTA-AOTC. If, on the other hand, the analog backup protection devices are not in the standard arrangement ensure that the ATXD signal is not required by the controller.

This follows from the description below.

An additional input signal to controller 42 is an analog one Temperature reference signal AT @ EF on conductor 56 from the analog Reserve protection devices 36. The ATREF signal is an analog voltage that is proportional to the desired operating temperature of the turbine, where the value is set to a safe level for all possible operating conditions. In In the embodiment of Figure 1, the ATREF signal from the analog backup protectors 36 generated. However, the ATREF signal can be from any suitable analog voltage source come and be fed to the controller. A value corresponding to the ATREF signal Can also be stored in the controller instead of this word from an external source to deliver. In any case, the ATREF signal can be used to calculate the BTMTEM signal used when the analog facilities are provided in the control arrangement are. The ATREF signal is also used by the analog backup protectors 36 used in a manner described in more detail below. The controller also receives a signal L 26 TC on conductor 55 from backup protectors 36. This Signal is used by controller 42 to determine when the control arrangement is up is in a temperature control at start-up or a warm-up control.

The analog temperature backup protectors 36 create two additional output signals, the temperature fuel control signal TFC on one Conductor 58 and a TRIP signal on conductor 60. The TRIP signal is called a The control signal is fed to a fuel control valve 62 via the conductor 60. It will used to control the supply of fuel to the turbine in the event of certain malfunctions to terminate within the arrangement, which are explained below.

Fig. 2 shows a schematic block diagram of an embodiment of the analog backup protection devices 36.

This circuit includes a selector 64 of known type for selection of the middle value, and for receiving the analogue Roservo protection Sonsoro input signals AOTA, AOTB, and AOTC on ladders 50. Selector 64 details to select of a middle word are described in U.S. Patent 3,492,588. The voter 64 to Selecting the middle word provides an ATXD signal on conductor 54 to the controller 42.

As mentioned earlier, the ATXD signal picks up under normal operating conditions of the sensors show a value in the middle of the values of the signals that the Selector 64 are supplied. Furthermore, the ATXD signal usually has one Word that is roughly proportional to the mean exhaust gas temperature of the turbine. the ATXD, BTMTEM and ATREF signals are all fed to a summer which is called Connection 66 is shown where these signals are algebraic to an input signal for a variable gain amplifier 68, the output of the variable gain amplifier 68 a TFC signal to the low gate 34 and to a threshold detector 51 supplies. The threshold value detector 59 generates the L26 TC signal, which is fed to the controller will.

The ATXD signal is applied to summing junction 66 through a resistor 70, and the BTMTEM signal is applied to connection 66 via resistor 72. The ATREF signal, the safe temperature reference, is the connection point 66 via a resistor 74 and via line 56 to the controller. The ATREF signal is connected to a voltage source V and the ground potential via a sliding resistor 73 derived.

Referring to Figure 2, the ATxD signal also becomes two conventional comparator / amplifier lock circuits 76 and 78 supplied. Each of the comparator latches has a voltage reference input signal of respective wiper resistors 80 and 82, both between a voltage source V and ground are un a reference voltage for comparison with their corresponding To enable input signals. The comparator latch circuit 76 receives from Sliding resistor 80 has an input voltage that is set to a specific voltage value is set so that the comparator circuit is energized when the output ATXD from counter 64 assumes a high value, which is the specific value of the wiper resistance 80 supplied voltage exceeds.

Similarly, the wiper resistor 82 is adjusted so that that the comparator latch circuit 68 is energized when the ATXD signal a assumes a small value beyond the specific voltage setting of the drag resistance 82 lies. During the operation of the trip circuit of the analog backup protection devices, if two or more sensors supplying the AORTA to AOTC signals to the counter 64, are short-circuited, the ATXD signal typically goes to a low or negative value and energizes the Kemparator lock circuit 78. Similarly the output signal ATXD goes high and energizes the comparator latch circuit 76 when two or more of the sensor input signals contain an open state.

The comparator outputs are all via their respective output conductors 84 and 86 are fed back to their latch circuits to cause the comparators put themselves in a locked state when aroused.

Whenever one of the comparator latches is energized, will the output of the circuit through an OR gate 88 passed through, which generates the TRIP signal on conductor 60 to control fuel control valve 62 (Fig. 1) to activate and stop the fuel supply to the turbine.

Furthermore, the ATXD signal can have an average value due to the sliding resistance 80 if the temperature of the turbine is too high Values.

This also creates the TRIP slenal.

When the turbine is shut down, it stays shut down until it is restarted by the intervention of operating personnel. To the fuel supply To restart the turbine, the operator must press a reset switch 90 press (Fig. 2), whereby a suitable potential, e.g.

Ground potential, is applied to both locking circuits 76 and 78. This ground potential resets the excited comparator, which causes the TRIP signal is overridden, causing the fuel control valve to open and a Fuel flow to the turbine hb takes place. Put the Brennsteffzmuir towards the turbine in connection with the entire turbine start no part of the subject matter of the invention represent.

Ver a complete description of the operation of the invention it is deemed distributable to use the memory map shown as an example in FIG. 3 for the storage of programs and data to be considered in the memory of the programmable controller 42 has been stored. The memory map shown as an example is divided into eight parts; (1) input data, (2) output data, (3) constants and mask, (4) main status program, (5) working area (scratch), (6) temperature control program, (7) further control programs, and (8) Sequence program. The main state program can be viewed in the present embodiment as an organization program, since it reads out all the information in the controller, and transfers the Controls control or regulating information from the controller to the turbine. The main state program is similar to a program disclosed in U.S. Patent No. 3,969, above 722 is described and there as U triggers. and standard status program "(ISSP.) referred to as.

The temperature sensor input signals are controlled by the main status program from ATCX1 to ATCX12 and AOTA to AOTC in Fig. 1 into the data input part of the memory 3 read in as temperature sensor states and temperature values. aside from that the ATXD, ATREF and L26TC signals are transferred to the Read memory. All of these input signals are in digital form in the data input section of the memory after the execution of an analog / digital conversion.

The data output part of the memory according to FIG. 3 contains calculated Data in the form of a calibration or fuel control signal to control the turbine, whereby this signal results from the execution of the temperature control program, which consists of the three sub-sections TCC, TCA and PPR. As shown in FIG the temperature control program is used to measure the temperature of the turbine and calculate the value of the calibration signal ru. The through the temperature control program calculated values are then stored in the data output section of the memory to get to the turbine as an output signal via a digital / analog converter.

The constant and mask part of memory is for completeness only sake present to show that the memory in a conventional manner this type Saves data to Vez through the program. The working part is for similar reasons (scratch) or memory shown to show that the programs are part of the memory used in the data during the execution of the program registered and read out.

The other control program parts of the memory in FIG. 3 are only shown to show that other programs are stored in memory programs for regulating the speed / load and the starting circuits 38 and 40 may be provided. The end part of the memory, the sequence program, is the For the sake of completeness, given to a program for simulating relay logic etc. in the form of an electrical ladder diagram. Min program this Art is described in the above US patent application and referred to as "application program" marked.

Mine detailed description of the main status and sequence program is not included in the present embodiment. A detailed one Description of programs of this type can be found in the aforementioned US patent No. 3 969 722. A description of an analog to digital conversion program for converting the sensor input signals into digital values is part of the subject matter of the invention not included, as analog / digital conversion programs and hardware are known and inclusion does not improve an overall understanding of the invention would.

Reference is now made to FIG. 4 which is a flow diagram illustrating the overall program of the present invention for controlling the gas turbine 10 shows. The program consists of the main status program (MSP), a sequence program (SEQ) and a temperature control program that includes a thermal line calculation subroutine (TCC), a temperature calculation subroutine (TCA) and a temperature adjustment subroutine (PPR) contains. The programs are sequentially looped as shown executed in such a way that on each cycle through the loop the program returns from the PPR to the MSP.

If, referring to FIG. 4, the control arrangement of the present Invention is started first, the controller 42 causes an entry (entry) in the main state program (MSP) in an action block 92, wherein the program the Input signals ATCX1 to ATCXi2, AOTA-AOTC, ATXD, HTREF and L26TC in the data input area of memory reads. After the input data is saved, the MSP enters Block 94 and sends output signals BTMTEM and other signals, not shown, from the data output area of the memory to the turbine. Obviously there are no data in the data output area during the first cycle through the program of memory. After the first or subsequent runs through the program, However, there is data in the data output area of the memory.

The program now advances to the sequence program (SEQ), provided this is is provided in the rule arrangement, whereby the SEQ is executed to set a relay or to imitate logic controllers by having relay coils, contacts, timing devices etc. are simulated to output control signals for the turbine develop to operate various indicator lights, coils, coil drivers etc., which are not shown. The information results obtained from running the SEQ program are obtained in the data output part of the memory for the subsequent Transfer to turbine from block 94 of the MSP saved.

After the SEQ program has been executed, the Temperature control program at TCC, the thermocouple calculation subroutine of the block 98. The TCC sub-rule has one primary function, which is to provide validity or to determine the reliability of the temperature sensors of the turbine in that the sensor words have been checked that correspond to the sensor temperature readings ATCX1 to ATCX12 and AOTA to AOTC in the data input area of the memory (Fig. 3) corresponded. In the preferred embodiment, this verification is carried out by the TCC program made, with a special bit in each word corresponding to the sensor readings is checked. This bit in each of the sensor words is used as the validity flag or validity flag, which is used during the analog / digital conversion of all sensor signals ATCX1 to ATCX12 and AOTA to AOTC is set or reset. It is known that overflow and underflew perception techniques usually in analog / digital calculations used to determine if the value of an analog signal is above either or below specific values. Min further way to validate To determine the sensor resistances is to use only arbitrary maximum and Set minimum values for the sensor words and the actual value of each word Compare with the specified values ru, and add a flag set one of the predetermined values exceeded will.

The TCC program enters the TCC subroutine at an action block 100 occurred. The primary purpose of the TCA subroutine is to have a common or calculate mean temperature from the number of valid readings that were previously calculated in the TCC subroutine. The TCA subroutine effects upon completion an entry into the PPR subroutine represented by action block 102 is. The PPR subroutine based on the results of the computed joint or mean temperature obtained by the TCA subroutine the output calibration signal BTMTEM.

Upon completion of the PPR subroutine, the program returns to the MSP and the above sequence is repeated.

As already mentioned, the BTMTEM signal is generated during the execution of the Transfer block 94 of the MSP to the turbine.

The entire sequence of the TCC, TCA and PPR subroutines is now described in Connection with FIGS. 5 to 8 outlined, the in the form of a flow chart Provide details of the operation of these subroutines.

According to FIG. 5, the TCC subroutine is entered directly from Block 96 of the sequence program of FIG. 4. The TCC0 subroutine represents a relative simple subroutine as represented by action block 104 in which a program to set the analog-to-digital (A / D) conversion error conzeichen bits in a word in memory for each invalid or incorrect Sensor reading is denoted by TM @@@@. As indicated in block 104, corresponds to an identifier bit for one of the ATCX1-ATCX12 and AOTA to AOTC signals or states. this will realized by the TCC subroutine that did the previously mentioned identifier bit in each of the sensor words is checked for a corresponding Error flag bit in place TMERWD in the working memory according to the state of each Set or reset sensor identification bits. Another error flag is set if its corresponding sensor word flag is invalid otherwise the error flag is reset or turned off. An error flag that is set indicates that this flag bit corresponding sensor (derived from a corresponding sensor word) either open or short-circuited, which indicates an invalid reading.

The TCA subroutine now enters a program loop that exits blocks 106, 108, 110 and 112. A test is carried out in this loop, to determine how many, if any, of the sensor input readings of these read values is invalid, as indicated by the error flag bits set in Thermocouple error word TMERWD is defined. After each entry into this loop a test is carried out in block 106 on a bit of the TMERWD which corresponds to one of the Sensor input read values or words ATCX1 to ATCX12, AOTA to AOTC, to decide whether an error flag is set or reset in the TMERWD is. Every time a flag is tested in TMERWD whether this bit is set which indicates that the corresponding sensor word must be rejected, the program exits block 106 with a YES jump to the action block 108 enters. In block 108 a current storage of the number of rejected or invalid sensor readings are kept available.

This storage of the rejected read values can be done in many ways be performed. In the embodiment described, a program counter is used used. Before entering the block 108, this counter is fed with a number, which is indicative of the number of sensor inputs (in this example 15). Each time block 108 is entered, the counter is reset by the value 1. In this way the number in the counter constantly shows the number of remaining good readings (i.e. the number of valid sensors included in the rule arrangement available).

Each time the block 106 is entered, an entry is made by the NO -Branch to block 110 performed when the flag bit tested in TMERWD is reset, which indicates a valid reading. The block 110 represents an action block within which the TCA subroutine the maximum Temperature (TMAX) or the maximum value of the sensor readings, the minimum temperature (TMIN) or the minimum value of the sensor readings and the total temperature (TXSUM) or finds the sum of the sensor readings. It should be noted that the values of TMAX, TMIN and TXSUM constantly with the non-rejected or valid sensor readings are related, since entry into block 110 is always via the NO branch of block 106 occurs.

After each flag bit in the TMERWD location has been tested, the program through a final decision block 112 and via a YES branch to block 114.

At block 114, a common or mean turbine temperature is established calculated by storing a value that the temperature identifies a place TXAVGN, where the word of TXAVGN corresponds to the value TXSUM, which is divided by the number (#) of good readings previously in block 108 was saved. Upon entering block 114, the one placed in TXAVGN Value represents the actual, mean exhaust gas temperature of the turbine, provided all readings the temperature sensors were recognized as valid.

However, if one or more sensor readings were rejected, i.e. were recognized as invalid, the value stored in TXAVGN represents an average Temperature that is common to the valid temperature sensor readings.

There is now an entry into a decision block 116 in which a test is performed to see if the difference between TMAX and TMIN is less than a constant LTXSPD that is in the constant range of memory is saved. This test checks whether the flow between TM&X and TMIN is Uborg Large. As long as the Strouung is not excessive, which indicates the temperature sensors will output readings within the limits occurs exits the program through a NO branch and through a block 118 to point TCAC50 there. Block 118 is not an action block, rather it is a doscriptor included to indicate that the program averaged and calculated the actual Use temperature TXAVGN as mean temperature TXAVG. TXAVG is a place in memory.

If the temperature spread is too large, (Fig. 5) this indicates that there is, or possibly, a possible combustion problem in the turbine a temperature sensor delivers an incorrect reading, and the Iluft program by the YES branch of block 116 to point TCAB10 of FIG. 6. Possible problems, which may exist involve the problem that a temperature sensor is defective works, making this sensor either an artificially low or high reading that does not indicate an invalid sensor state (provided that it is artificially low or high reading as a factor in the total, common or average exhaust gas temperature the turbine goes down, it can cause the turbine to be artificially ignited, to generate a higher temperature than is required, or this reading can cause the fuel supply to be throttled, resulting in a lower temperature is generated as is desired. Excessive combustion in the turbine can lead to result in serious damage or deterioration of the turbine components, whereas too little combustion leads to a decrease in the efficiency of the turbine Consequence).

Another potential problem is a clogged fuel nozzle in one of the combustion chambers, providing an indication of a cold spot or a low temperature spot is caused in the turbine exhaust.

(Should this state occur, a limit violation reading will be used again cause the turbine to be operated with excessive combustion. The reverse An analogous case could also occur in the case of hot spots in the turbine, with in this case a malfunctioning nozzle delivering fuel to the turbine as required or specified). Because of the above issues the has been determined in the temperature variance test in block 116, it is then desirable identify actual or potential problems.

The flow chart of Fig. 6 shows the operations performed by the temperature control program be carried out first to the possible areas of burning problems in the turbine to identify and then the common or mean temperature recalculate for use in turbine control. When entering the Place TCAB10 in block 120 brings the program system parameters into a preparatory or Waiting position for testing and isolating the burning or sensor problems to serve. This is done by first setting upper and lower temperature limits be set up, with a storage space UPPER (upper limit) equal to the value from TXAVGN, the calculated common or mean temperature plus the value which is set by an upper temperature limit LTXDF1 in the constant range of the memory is specified. Similarly, there is a lower temperature limit set up in that a memory location LOWER is equal to TXAVGN minus the value of a lower temperature limit constant LTXDF1 is set. At block 120 enter LTXDF1 and LTXDF2 the maximum upper and lower temperature deviation limits of TXAVGN at. In addition, during the preparation to recalculate the turbine temperature the denial counter provided in block 108 of FIG. 5 is cleared.

A decision block 122 is now entered in which again a test is carried out similar to the one previously in the block 106 of Figure 5 to determine if any sensor input read represents an invalid or rejected reading.

For each sensor reading found to be invalid, will entered a rejections memory block 124 via the YES branch of block 122, by storing the rejected sensor readings, as previously in connection with block 108 of FIG. The exit from block 124 enters a done decision block 134.

The program continues to loop through the NO branch of the block 134 back to block 122 until all sensor readings have been tested.

Reference is now made to the NO branch of block 122, the returns to decision block 128. Every time the block 122 is entered entering block 128 whenever the sensor reading under test is not rejected. A test is performed at block 128 to determine whether the individual temperature readings ATCX1 to ATCX12 and AOTA to AOTC specified temperature is greater than the lower limit previously set in block 120 was established. Any reading that is not larger is considered a rejected reading stored or recorded in block 124. The rejection of a reading in the block 128 indicates a burn or temperature sensor problem.

For every reading that is greater than the lower limit, a YES branch taken to another decision block 130.

In a block 130, a test similar to that in block 128 is carried out, to determine if the sensor readings are less than the upper limit that was previously set in block 120. Any of those readings that are out of bounds causes the program to continue via the NO branch and this reading as a rejected sensor in block 132. Block 132 returns to block 126. For each reading that is within the limit, the program takes its passage via the YES branch, which enters block 126. It should be noted that the denials memory block to which an entry from block 130 he follows, is shown as block 132 but that it is the same counter as the blocks 124 or 108 is realized. These blocks are still there for the sake of simplicity shown separately because they have different entry points in the subroutine.

In block 126 a new temperature sum is accumulated or calculated, as the place TXSUM is equal to its currently

existing word plus the sum of the non-rejected sensor readings (i.e. the number (#) of remaining good readings) is set. The exit from block 126 to done decision block 134, branching via the NO exit back to block 122 until each of the sensor readings for the inputs ATCX1 to ATCX12 and AOTA to AOTC have been tested. The workflow this loop is in some ways similar to that previously in connection with Fig. 5 for plates 106, 108, 110 and 112. After all sensor readings are tested in Fig. 6, there is an output via the YES branch of block 134 to a point TCAC40, which leads to a block 136.

In block 136 a new common or mean temperature is calculated, where the location TXAVGN is updated to the content of the new or accumulated TXSUM divided by the number of new good readings, with the new There are good readings in blocks 124 and 132. The program is progressing now to a point TCA10 of FIG. 7 in a block 140. In block 140 tests the controller now determines whether there are hot or cold tunnels in the turbine combustion chambers, to identify possible burning problems. This is done in that the program Tests groups of temperature sensor readings that contain Corresponding groups of adjacent sensors, which are arranged on the circumference around the exhaust chamber are. For example, the 15 sensors that generate the signals ATCX1 to ATCX12 and AOTA to generate AOTC, divided into five groups of three sensors each. The program then tests each group of three sensors to see if the sensors are in each Group deliver valid read values lying within the temperature limit read values. If any group shows a cold spot inside the exhaust space, will a cold junction connector TCACS is set in the data output section of the memory. Provided Any group containing a hot spot reading becomes a hot spot flag TCAHS set in the data output section of the memory. Although in the flow charts of the Not shown in the present invention, the TCACS and TCAHS flags (flags) used by the program to provide an output signal during the process of the main state program to sound an alarm to the Operators indicate that either a cold or a hot spot is in the turbine is present.

Upon completion of block 140, a point TCAC50 is entered into a Block 142 entered. It should be remembered that from block 118 of FIG. 5 an input is made in the point TCAC50. as already described. With the Entry into block 142 is the common or mean temperature TKAVCl actual mean temperature previously calculated in Fig. 5, or they is the recalculated common or mean temperature as just related with Fig. 6 was described. In block 142 it is now desirable to run a test or a check with regard to the minimum number of temperature readings (i.e. ATCX1 to ATCX12 and AOTA to AbTC) to carry out the within the limits. This is done by the program taking the contents of a Subtracts constants in memory from the contents of the counter that counts the number of good readings indicates. As already explained, the counter in blocks 124, 132 or 108 was set. B.i an excessive number of temperature readings that are outside the limits becomes the flag TCATN in accordance with the results of this Subtraction either set or canceled (reset). TCATCN is set, when an overflow condition occurs indicating that there are too many temperature readings are invalid (e.g. if the number of good readings is less than 8). TCATCN is an abort flag that is tested in the PPR subroutine to start the program to cause the computer control or regulation to be aborted and to analog reserve protection scheme is passed over. As shown in block 142 is, the content of the location TCATCN is transferred to a location DTMABT in the data output part of the memory during the SEQ routine. With the conclusion of block 142 takes place an entry into action block 144.

At block 144, a test or examination takes place to determine whether an oversized change in common or mean temperature during the last pace.

temperature calculation has taken place. This is caused by It is checked whether the content of a storage constant LTXAVG is the same as the recalculated Temperature TXAVGN minus the old calculated temperature is TXAVG.

For example, if the content of LTXAVG is 25 ° F, i.e. 13.9 ° C, and wnn this is the maximum allowable temperature change between any two Entries in the temperature control program may occur, so will an excess temperature indicator TCAAVG is set. If the content of LTXAVG is smaller than 13.9 ° C (25 ° F) then the TCAAVG flag is reset or turned off.

There is now an entry into the block 146, in which the common or mean temperature is updated by the location TXAVG (old mean temperature value) is set to the newly calculated mean value TXAVGN.

If the analog backup protection devices are present in the arrangement there is an entry into the block 147. If the arrangement is under the sole Computer control or regulation is in place (no reserve protection), entry occurs into an operating temperature adjustment program PPr '. It is first assumed that the analog reserve protection devices are available in the Rogol arrangement.

There is therefore an entry into the block 147 in which a location of the working memory KVAL1 is equal to the difference between ATXD (the medium value signal) and TXAVG (the present mean temperature) is set. There is then an entry into decision block 148 of the PPR subroutine of Figure 8 in which a test is performed is used to determine whether the control arrangement is computer control or regulation should abort and go to the analog temperature reserve protection device 36 target. This test is performed by determining whether the abort bit DTMABT is set equal to a binary 1 (cf. block 142 of FIG. 7). Unless this Bit is a binary 1, the program follows a YES branch to block 150 in which the calibration or fuel control signal BTMTEM is reduced by a predetermined word the BTMTEM signal with each run through the temperature control program drops in step form towards the word zero. As already explained, will the BTMTEM signal to the analog backup protection devices during the execution of the MSP transfer. Then the PPR gives control back to the MSP for one Entry into the MSP from block 150. It should be remembered that, as already in Described in connection with FIG. 2, the adjustment signal BTMTEM does not have a control factor represents more and that thus the output of amplifier 68 is the algebrainch sum of the mean value signal ATXD and the analog reference signal ATREF, whenever the calibration signal BTMTEM is zero. When the computer output signal canceled since the BTMTEM signal has dropped to zero, it takes over in this way the analog backup protection device regulating the turbine to the temperature fuel control signal Route TFC on conductor 58 to low gate 34 for fuel flow to regulate the turbine. It is also important to point out that most commercial regulating or control computer of the type considered in this invention usually have test routines to verify the validity of the computer operation (e.g.

Memory parity, analog input / output accuracy, etc.) check ru. In addition, some type of watch dog timer) provided.

This time control device is queried periodically by the program, to make sure the calculator is working properly. The perception of anyone Malfunction of the computer can also be used to cause the TMTEM-Siganl is brought to the value zero in a similar manner as this in connection with block 150 is described.

Reference is again made to block 148. Provided the abort flag D! KAB is not set, this occurs Program with the NO branch and enters an action block 152. A delta temperature reference is used in this block DELR1 set in memory to a value equal to the temperature base (TBASE) minus the value of the analog reference temperature (ATREF). TBASE is a word which indicates a desired base temperature during turbine operation (usually from Operating personnel specified).

If the analog backup protection device is present in the arrangement is, the computation of DELR1 can be used as a factor in developing the correct one Use value for the BTMTEM signal. There is use for this signal due to the expected differences between the values of TBASE (e.g. 454.4 ° C) (850 ° F))) and ATREF (e.g. 426.7 ° C (800 ° F)), and the difference value (DELR1) between TBASE and ATREF serve as the desired reference temperature or temperature default value for summation with the temperature variables that are described in order to produce the calibration signal To generate BTMTEM It should be remembered that ATREF always has a value that the turbine temperature is safe under all operating conditions. Additionally will in block 142 a storage location KVALR1 is set equal to the correction value of KVAL1, which was previously established in block 147 of FIG. 7, where KVAL1 is a stepped value is (ramped value), which causes the BTMTEM signal to act like an integrated signal to change, thereby precisely regulating the operation of the turbine, so that large changes do not occur in the fuel supply.

The program now follows to a block 155 in which a test is carried out to determine whether the arrangement with temperature control (TEMP CONTROL?) is running, testing whether there is a flag L26TC in the working part of the memory a binary 1 is. Recall that the L26TC signal on conductor 55 of the Fig. 1 and 2 was read into the controller by the MSP. Regarding the threshold detector 99 in Fig. 2, L26TC goes to a binary 1 when the word of the TFC signal is a predetermined one Reached size, which indicates that the turbine during the start of the control arrangement has had a suitable warm-up period.

When the L26TC signal goes from a binary 0 to a binary 1, this binary 1 is stored in location L26TC and indicates to the program that the Turbine is at the correct temperature, which makes a transition to full Temperature control permitted.

If the arrangement does not work with temperature control (L26TC - 1), the program enters a block 154 via a NOT branch of block 155 a. However, it is assumed that the arrangement carries out temperature control, so that the program exits block 155 via a YES branch and into a Block 157 enters. In block 157, the difference between the base temperature is (TBASE) and the very precisely calculated mean temperature (TXAVG). A this difference proportional value is in a place KVAL2 in the main memory part of the memory.

A block 159 is now entered and becomes the value KVAL2 is tested to determine if it is less than or equal to a given constant which is shown as zero (O). If there is a difference between KVAL2 and the constant zero is present, a place is KVALR2 in the memory by Suitably changed increase or decrease in its value. As explained below KVALR2 represents a second correction factor that is used in the equation for Obtaining the temperature compensation signal used is going to the To regulate fuel supply to the turbine.

The purpose of changing KVALR2 is to tell the difference or to reduce the difference between TBASE and TXAVG. KVALR2 is controlled by a fine-tuning constant increased or decreased with any value. This way, KVALR2 has one very slow incline or rate of change, so that the difference between TBASE and TXAVG is gradually eliminated in order to reduce the offset and drift errors to compensate the arrangement introduced by said electronic elements will. If the difference is eliminated by matching, the entire error is of the arrangement to only one error of the temperature sensing part of the arrangement reduced as there is no discrepancy between the base temperature and the calculated medium temperature is present.

The value of KVALR2 also has maximum positive and negative Limits, which are determined by two places in the constant part of the memory, and represented in block 159 as + LKVAL2.

Following / @@ the tests in block 159 is followed by entry into a decision block 161 in which a test is performed to determine whether the absolute value of KVALR2 exceeded either the positive or negative limit which is determined by the places + LKVAL2. Unless KVALR2 is one of the limits has exceeded, the program enters a block 163 through a YES branch. At block 163 an alarm flag is set in the data output portion of the memory. This indicator can be used to turn on an alarm, when the main state program (MSP) receives the output data from the data output part of the memory sends. If this indicator is used to switch on an alarm, then so it can give a message to an operator that a certain malfunction is present, which causes such a large error that it cannot be corrected by matching KVALR2 can be compensated or calibrated.

Such errors can occur in the digital / analog converter of the controller output, available in various control amplifiers, tolerances of summation resistors, etc. be.

Once the alarm flag is set, the program occurs into a block 154, the purpose of which will be explained below. It is now assumed that KVALR2 is within the limits of + LKVAL2. The result is a NO branch taken from block 161 to action block 154.

In block 154, the word of the temperature compensation signal BTMTEM is thereby calculates that in a place BTMTEM in the data output part of the memory the algebraic Sum of the contents of the places DELR1, KVALR1 and KVALR2 is stored.

The program now returns to the main state program MSP in which BTMTEM is transmitted to the analog reserve protection device.

Reference is again made to the output of block 146 in FIG taken. A modification of this embodiment is shown in dashed lines in FIG of the invention in which the program can bypass the PPR subroutine and enter a PPR 'subroutine at block 156. The PPR 'subroutine is provided in the controller according to the invention when the analog backup protection system in the Overall arrangement does not exist. That is, if the entire control or regulation the gas turbine is realized by a fully digital implementation of the controller 42 will. When the PPR 'subroutino replaces the PPR subroutine, the BTMTEM signal on conductor 52 (FIG. 1) is fed directly to the low value gate 34 as the TFC signal. It is an integrated signal with the value: BTMTEM = # (TBASE-TXAVG) dt. The BTMTEM signal developed in block 156 becomes the data output part of the memory transmitted in the same manner as previously described in connection with block 154 and control returns to the MSP.

As mentioned before, the BTMTEM signal represents an analog signal. If the arrangement is designed as a purely digital control arrangement, in which 7 is used, the digital-to-analog converter of the digital controller has an integrator at its output to carry out the integration function as shown in block 156. It is important to point out that the value of BTMTEM, however, also, if desired, by programming the integration function can be calculated. this can be accomplished by adding a value V to the Is provided which is equal to TBASE minus TXAVG, and then the value V is compared against positive and negative value of X and -X for a particular one Variation of the turbine temperature are characteristic, and that then the value of BTMTEM equal to BTMTEM plus or minus a corresponding integration constant K or -K is set to make the BTMT signal positive or negative depending on it integrate whether V is greater than X or less than -X.

Reference is now made again to block 154 of FIG. In this block where BTMTEM is computed the arrangement will still be correct work even if DILR1 is omitted from the equation. The value of zUtl is relatively small because the difference between the values of TBASE and ATREF is small. as The only result is the omission of DELR1 from the calculated value BTMTEM a very small error in the fuel control signal. The accuracy of the regulation however, the turbine temperature is increased when the DELR1 signal is taken into account.

For the sake of complete disclosure, a copy of an assembly language program listing is included of the temperature control program for operation in the aforementioned "Directo-Matic" logic controller attached as "Appendix A", which is part of this specification. It is recognized the system software (i.e. programs) is sometimes characterized by minor bugs known as programming errors (bugs) and how to detect them and / or diagnosis are sometimes required for long periods of time. Usually lies the correction of such errors within the skill and control of system programmers. Accordingly, the attached list may well have one or the other programming error but all of the errors detected could be eliminated with the skill of system programmers Fixed.

The following are two different forms of a second embodiment of the present invention, in analog form, described. The first of these forms represents the basic arrangement, while the second form a variation of the first in which certain factors such as tolerances and deviations be compensated in various components, e.g. the amplifiers.

Reference is now made to Figures 9, 9a and 9b.

Fig. 9 is an illustration showing the relationship between Figures 9a and 9b shows. 9a and 9b show the first form of the second embodiment the invention an analog controller for monitoring the sensor signals ATCX1 to AOTC, coming from the turbine sensors 26 on conductors 48. In this embodiment the analog controller of FIGS. 9a and 9b replaces the programmable controller 42 of FIG. 1. Furthermore, the analog temperature backup protection device is in this form of embodiment 36 of FIG. 1 is not used to regulate the fuel supply to the turbine. this is shown in Fig. 9b, in which the BTMTEM signal from an integrating amplifier 232 is fed directly to the low value gate 34, as indicated by the dashed line Line around the analog temperature backup protection device 36 is shown as previously described in connection with FIG.

Reference is now made to Figure 9a. As shown in Fig. 9a, Each of the sensor signals ATCX1 through AOTC on conductors 48 becomes a corresponding one Comparator 158 supplied, which is shown in dashed lines. Though only two pairs or groups of comparators 158 are shown, it should be noted that a comparator is available for each sensor signal. Each of the two comparator circuits in the Ko paratoren 158 receives a reference signal from a corresponding reference source. For example,

a comparator circuit 160, labeled COMP HI, in each of comparators 158 have a high reference signal RHI on conductor 162 from one high reference source 164, REF HI.

Similarly, a lower comparator circuit 166 includes COMP LO, a low reference value signal RLO at one in each of the comparators 158 Conductor 168 from a low reference signal source 170 labeled REF lt is.

In the embodiment shown in FIGS. 9a and 9b, the Validity of the sensors 26 is determined by the comparators 158 which determine the values of the Compare the ADCX1-AOTC signal with the RLO and RHI signals. Lie in normal operation the values of the ATCX1 to AOTC signals within the limits set by the RLO and RHI signals are fixed, and the output of all comparator circuits 160 and 166 is a binary O. The outputs of each comparator pair are via corresponding Conductors 174 and 176 are fed to a corresponding OR gate 172. As long as that Signals on conductors 174 and 176 to an OR gate 172 are both binary zeros the output of this OR gate generates a binary 0 on a corresponding conductor 178. The output of all OR gates 172 becomes an appropriate switch from a Variety of switches in a sensor selection switch circuit 180, labeled 1 supplied. Two of these switches 182 and 184 are shown. Additionally receives each of the switches the sensor signal, which the comparators of the switch concerned is equivalent to. For example, switch 182 receives the ATCX1 sensor signal that this Switch 184 supplies the corresponding comparator, and the switch 184 receives the AOTC signal etc. Each of the plurality of switches (e.g. 182 and 184) has one Inverter input connector and each switch is capable of its sensor input signal an averaging circuit 192 labeled # 1 over a plurality by appropriate ladders when the receipt of this Switch is a binary 0 on conductor 178. When the signal on conductor 178 is a binary 1, the switch that receives this signal is opened (overridden), to prevent the passage of this sensor input signal.

As an example, like comparators 158 and selector switches 180 work, assume that the ATCX1 signal is either the lower or the upper Exceeds the limit set by the RLO and RHI signals. In this The appropriate comparator of the two comparators 160 or 166 determines the situation the validity of the sensor that generates the ATCX1 signal, in which a binary signal with the value 1 is generated on either conductor 174 or 176, the conductor is determined by the activated comparator. When this happens, the binary continues Signal with the value 1 the OR gate 172 is able to use a binary lock signal the binary value 1 to the switch 182, thereby preventing the ATCX1 signal passes through selector switches 180 to averaging circuit 192.

The averaging circuit 192 generates an output signal TXAVGN on a conductor 194. The value of the TXAVGn signal is always proportional to the average the values of the ATCX1 through AOTC signals passing through the selector switches 180.

The TXAVGN signal becomes the positive terminal (+) of an algebraic Summing member 196 supplied. Summer 196 also receives an input signal on conductor 192 from an LTXTF2 reference source 200. Based on the description the first embodiment, it should be remembered that the reference source LTXTF2 a indicates the lower limit of the temperature deviation of the mean value of the turbine temperature, how it is determined by the TXAVGN signal.

The output of summer 196 provides a low reference value (NEW RLO) the turbine temperature on a conductor 102 which has the value (TXAVGN - LTXDF2) owns. The NEW RLO signal is supplied to each comparator from a variety of comparators 204 supplied, which are labeled COMP NEW LO. It should be noted that each of the ATX1 to AOTC sensor signals A corresponding comparator 204 is assigned to each although only two of them are shown. The purpose of all of these comparators 204 consists in comparing the NEW-RLO value with the one corresponding to the respective comparator Compare sensor input signal to determine if there is a possible combustion problem or an abnormal sensor reading in the turbine in the area of that sensor is present, which generates the corresponding sensor signal.

During normal operation, if all ATCX1 to AOTC signals are within the The limits of the temperature deviation, which are given by the NEW-RLO signal, the output of all comparators 204 represents a binary 0. The output of all comparators 204 is selected from a plurality of via a corresponding line Conductors 206 are fed to a sensor selection switch circuit 208, numbered # 2 is designated.

Selector switches 208 are similar to selector switches 180 and operate in the same manner as previously described in connection with switches 180. It should be noted that for each of the sensor signals ATCX1 to AOTC in the selector switches 208 there is a switch. For example, the ATCX1 signal is via a conductor 210 the top switch 212 of the selector switch 208 and the ATOC signal is a switch 214, the lower switch, via a conductor 216. So long like the output of all comparators 204 represent binary zero values, the corresponding switches 212 to 214 are set in the position, the ATCX1 to AOTC signals to pass on a variety of conductors 218 and use them as ATCX1 'to AOTC' signals to a second averaging circuit 220, with the number # 2 denotes to feed.

The averaging circuit 220 has the same structure like the averaging generator 192 described above. The averaging circuit 220 generates an output signal TXAVG on conductor 222. The TXAVG signal has a value proportional to the calculated mean turbine temperature.

Reference is now made again to the comparator circuits 204 of FIG. 9b taken. When any of the ATCX1 through AOTC signals is greater than the lower reference limit signal NEW RLO is the output of the comparator or comparators that cross the limit Sensor signal received on a binary 1. This binary signal with the value 1 opens via the conductor 206 that switch which receives this signal to the passage of the sensor input signal to the selector switches 208. It lets itself on in this way, recognize that the output of averaging circuit 220 is steady generates a TXAVG signal which has a value which is the mean value of the signals that passed through the selector switches 208.

The TXAVG signal on conductor 222 becomes a negative input terminal (-) of a second algebraic summing element 224 is supplied. The summer 224 also receives a base temperature reference signal TBASE on conductor 226 of FIG a TBASE-REF source 228. As mentioned earlier,. the analog The backup protection system of FIG. 1 not used when the TBASE reference signal is used a corrected temperature signal for the fuel control of the turbine to calculate. This is corrected in the embodiment according to FIGS. 9a and 9b Temperature signal given by KVAL1 'passed through summer 224 on the conductor 32 is generated. The KVAL1 'signal has a value of TBASE minus TXAVG. That KVAL1 signal on conductor 230 is used by a conventional integration amplifier circuit 232, which integrates the KVAL1 'signal over time to generate the BTMTEM or To generate TFC signal for the low value gate 34 of FIG. 1 and to control the To use fuel feed to the turbine.

Reference is now made again to the outputs of the comparators 204 in Figure 9b. It should be noted that each of these comparators has a corresponding one Conductor 234 with the input of a "number of good readings <8 decoder" circuit 236 connected is. Circle 236 represents a conventional decoding network that monitors the binary signals on conductor 234, 15 in the preferred embodiments, to see if the number of good readings, as indicated by the outputs of the Comparators 204 is set to be less than 8. As long as 8 or more of the Signals on conductors 234 are binary zero values, the output of the decoding network 236 represents a binary 0 on a conductor 238. The output signal on the conductor 238 from the Dokoder 236 is designated as a RESET-INT-SIngal to reset the integrator 232 when the signal goes to a binary 1. Provided fewer than 8 of the sensors 26 are outside the limit values or are invalid Readings generate, the decoder 236 generates a binary 1 as an output signal to the integrator 232 reset.

This reset causes the output signal BTMTEM of the integrator 232 is stepped to the value zero, whereby the fuel supply to the turbine is switched off. In the embodiment of FIGS. 9a and 9b, a fail safe operation of the turbine produced in that continuously the temperature conditions of all sensors 26 are monitored to the turbine regulate, and to shut down the turbine if a catastrophic combustion problem Type or malfunction of an excessive number of temperature sensors occurs.

Reference is now made to Fig. 10 which shows a modification of the embodiment Figures 9a and 9b shows. In Fig. 10 have components that correspond to the elements of the 9b correspond to the corresponding reference numerals, but with a prime are provided at the end of the reference number (e.g.

Summer 224 'and integrator 232'). Fig. 10 contains the analog Temperature reserve protection device 36, as before in connection with FIGS. 1 and 2 has been described. The TXAVG signal on conductor 222 from the averaging circuit 220 (Fig. 9b) is fed to the algebraic summer 224 '. In this embodiment the summer 224 'receives the signal ATXD at its positive input terminal with middle value as a reference signal from the analog backup protection device 36 on conductor 54. The output of summer 224 'represents the calculated corrected turbine temperature presented as a signal KVAL1 on conductor 240 is shown. The KVAL1 signal becomes a positive input terminal (+) of one second algebraic summing element 242 supplied. bas output signal of the Summing element 242 provides an input signal on conductor 244 to a conventional integration amplifier 232 '.

The output of amplifier 232 'is the BTMTEM fuel control signal, which is fed to the analog backup protection device 36 on the conductor 52. It note that the BTMTEM signal comes from the output of amplifier 232 'through a conductor 248 is fed back to a negative input terminal (-) of summer 242 will. The purpose of routing the BTMTEM signal back to the input of summer 242 consists in algebraically combining the BTMTEM signal with the KVAL1 signal, to attenuate the input signal to amplifier 232 'to avoid the BTMTEM signal changes very strongly with rapid changes in the KVAL1 signal. In this way causes the BTMTEM signal to change smoothly and gradually, thereby causing will cause the TFC signal on conductor 58 to have a smooth and gradual regulation the supply of fuel to the turbine.

In the embodiment according to FIG. 10, instead of the output of the integrator 232 'the BTMTEM signal to the value zero, as before in connection with FIG. 9a and Fig. 9b when the RESET INT signal on conductor 238 is a binary 1 assumes. When this is done, the BTMTEM signal is considered to be generated of the TFC signal in the analog backup protection devices 36 ineffective, as before has been described in connection with FIG. 2.

The second form of the second embodiment of the present invention is illustrated by Figures 9 ', 9a' and 9b '.

The similarity between the two forms of embodiment will be immediately apparent from the figures (Fig. 9a is the same figure like Fig. 9a '), the similarity between the two forms of embodiment becomes further identifiable as practically the same reference numerals for those Components are used to describe the components of the first form were used.

Fig. 9 'shows an illustration showing the relationship between the Fig. 9a 'and 9b' indicates. Figures 9a 'and 9b' show as the second form of second embodiment of this invention an analog controller for monitoring the Sensor signals ATCX1 through AOTC on conductors 48 from turbine sensors 26. In In this embodiment, the analog controller of FIGS. 9a 'and 9b' replaces the programmable one Controller 42 of FIG. 1.

In this embodiment, the analog temperature backup protection device 36 used to control the fuel supply operation to the turbine. This is shown in Fig. 9b ', according to which the TFC signal from the analog safety device 36 is fed directly to the low value gate 34, as previously in connection with Fig. 1 was described.

As far as FIGS. 9a and 9a 'are identical, a repetition is made the description of this representation is not considered necessary. It is now on 9b 'and the comparator circuits 204 are referred to. If one of the ATCX1-bis AOTC signals is greater than the lower reference limit signal NEW RLO, the outputs go of the comparators (or the comparator) that is out of bounds Receives sensor signal on a binary word 1. This binary 1 signal opens the Switches receiving the signal on conductor 206 to allow passage of the sensor input signal for the selector switch 208 to prevent. It can therefore be seen that at the exit of Averaging circuit 220 always generates a TXAVG signal that has a value which is the average of all the signals passing through the selector switches 208 is equivalent to.

The TXAVG signal on conductor 222 becomes a negative input terminal (-) of a second algebraic summing element 224 supplied. The summing member 224 also receives a base temperature reference signal TBASE on conductor 226 from FIG a TBASE-REF source 228. The output of summer 224 represents the represents the previously described KVAL2 signal on conductor 230, the value of which is equal to TBASE minus TXAVG is. The KVAL2 signal is used in a conventional threshold amplifier circuit 232 with dead zone, which either has a zero signal or a positive or generates a negative output signal according to the value of the KVAL2 signal. Unless that KVAL2 signal is zero, the output signal of the detector 232 is zero. Unless, however the KVAL2 signal goes above zero, the output of the detector 232 goes on a positive value. If the KVAL2 signal goes below the word zero, behaves the detector 232 is reversed. Then the output of the detector 232 goes into the negative.

The output of the detector 232 is via the conductor 233 a conventional integration amplifier 235 supplied to the input signal via a Zoitporiodo integrated to at a slow constant fine-tuning rate to generate said KVALR2 correction signal on conductor 237. The KVALR2 signal is fed to two conventional comparator limit value circuits 239 and 241 and with a positive and a negative reference limit bet signal from a + KVAL2 and -KVAL2 limit reference sources 243 and 245, respectively. The output signal Each of the comparators 239 and 241 become respective inputs of an OR gate 247 supplied. When the KVALR2 signal is within the limits of the # LKVAL2 reference signals the output signals of the comparators are both at a binary value 0, thereby keeping the OR gate 247 deenergized. If a system offset or Drift error occurs that is outside the limit values of the # LKVAL2 reference signals described is, the corresponding comparator of the two comparators 239 and 241 represents the Limit condition and supplies a binary 1 signal to the OR gate 247, whereby the latter generates a binary 1 signal to trigger an alarm (not shown). As already explained, the alarm can be used to prevent the Operating personnel to indicate a condition that has been exceeded, which for a possible Disturbance of one of the aforementioned elements is characteristic.

Reference is made further to Fig. 9b '. The calculated mean Temperature signal TXAVG becomes a negative input terminal via conductor 249 (-) of a summing element 251 is supplied. Summer 251 also receives an a positive input terminal (+) the ATXD signal with the middle value of the analog backup protectors 36 via conductor 54. The TXAVG and ATXD signals are algebraically combined in the summer 251 to form said correction signal KVAL1 on a conductor 253 to generate.

The KVAL1 signal is proportional to the difference between the calculated mean temperature (TXAVG) and the signal bit mean value (ATXD). It is on it reminds that the ATXD signal is derived from the AOTA through AOTC signals, and that the ATxD signal has a value that is essentially same is the mean of the values of the AOTA to AOTC signals. The ATXD signal is therefore essentially proportional to the mean turbine temperature produced by the three Sensors is derived that generate the AOTA to AOTC signals.

The purpose of combining the ATXD and TXAVG signal is to to compensate or correct the expected differences that exist between the very accurate TXAVG signal (calculated from 15 possible sensors) and the less Exact ATXD signal is available, which is derived from the three sensors to generate the correction value signal KVAL1.

The KVAL1 signal on conductor 253 becomes a positive terminal (+) of a further summing element 255, the output of which is connected to the input a conventional integration amplifier circuit 257 is connected. The output signal of amplifier 257 is the aforementioned KVALR1 signal on conductor 259 which a negative input terminal (-) of summer 255 and an output summer 261 is fed.

The KVALR1 signal is fed back to the summing element 255 and with combined with the KVAL1 signal in order to carry out an attenuation in such a way that radical Changes in the KVAL1 signal cannot be found again in the KVALR1 signal It is important that it should be noted that the KVALR1 signal is a much faster changing Signal than the KVALR2 signal and as the primary fuel control parameter for development of the BTMTEM signal on conductor 52 is used.

The KVALR1 and KVALR2 signals become algebraic in summer 261 combined. The summer 261 receives the named deta temperature preset reference signal DELR1 from su jier 263 through conductor 265. Has the DELR1 signal a value equal to the difference between the TBASE signal on conductor 267 and the ATREF signal on conductor 269 from the analog backup protection 36 is proportional. The output of summer 261 is the BTMTEM signal on conductor 52 which has a word proportional to the algebraic sum is the DELR1, KVALR1 and KVALR2 signals. With reference to FIG determine how the BTMTEM signal in the analog reserve protection device with the ATXD and ATREF signals are combined to produce the temperature fuel control signal TFC which is applied to the low gate 34 of FIG.

The output signals of the comparators 204 of FIG Fig. 9b 'is referred to. It should be noted that each of these comparators has one corresponding conductor 234 with the input of a "number of good readings <8 decoders" circuit 236 is connected. This circuit 236 is a conventional decoding circuit which the binary signals on conductor 234 (in preferred embodiments 15) monitors to see if the number of good reads caused by the output signals of the comparators 204 is determined to be less than 8. As long as 8 or very signals on conductor 234 have the binary value 0, is the output signal of the decoding network 236 a binary O on conductor 238. The output on conductor 238 from Decoder 236 is referred to as a RESET-INT signal which is used to reset the two Integrators 235 and 257 are used, when this signal is on the binary Value 1 goes. If fewer than 8 of the sensors 26 exceed the limit values If values or invalid readings are generated, the decoder 236 generates a binary 1 as a Output to reset integrators 235 and 257. This reset causes the output signal BTMTEM of the summing element 261 to have the value zero staging allowing the analog backup protectors 36 to be the turbine with a reduced safety temperature in a fail safe operating mode operate as previously described.

The following is a digital or third embodiment of the present Invention for calculating the value of the temperature fuel control signal TFC specified. Here, as was the case with the analogous embodiments, two forms are described, the first form, a type of basic form, and the second Shape that allows the compensation of tolerances and fluctuation factors, such as has been discussed before. Fig. 11 is a diagram showing the relationship 11a to 11d show one below the other, the basic form of this third embodiment affect.

(Fig. 11 'is a similar illustration showing the context of Fig. 11a 'to 11e' for the second form of this embodiment indicates the later is described). Fig. 12 shows the relationship of Figs. 12a to 12d, all of them together a timing diagram of the relationships between the various signals indicate that by the digital controller of FIGS. 11a to 11d and FIGS. 11a 'to 11e 'can be generated. The following description of the controller refers to the timing diagram 12a to 12d are referred to. As before, in the explanation the two forms of this third embodiment use the same reference numerals. It will be the common ones first Parts of the two forms of this considered third embodiment of the invention. Fig. 11a (and also Fig. 11a ') FIG. 12 shows a clock generator 250 which has a sequentially occurring clock signal CLK a conductor 252 for use in various logic circuits and elements of the controller. The CLK signal is shown above in Figures 12a and 12b. In Figure 11c (and 11c ') is a manually operable reset switch 254 (MAN REST) shown, which has a terminal connected to a voltage source V. is. When the MAN RESET switch is in the closed position, a reset signal is issued generated for placement on a conductor 256. This reset signal becomes the various Registers, counters, flip-flops and elements of the controller are fed to the arrangement to trigger at a start. The MAN RESET switch provides the reset signal for the arrangement as an input to an OR gate 258, whereby the OR gate into the Position is set, a binary trigger pulse with the value 1 is a delaying one monostabilon multivibrator 260 feed. The delaying monostable multivibrator generates a default output pulse on conductor 262, one by two counters Presetting to give the number of good read values counter 1 and 2 "circuit 264 and 266 in FIGS. 11c and 11b (also in FIGS. 11c 'and 11b') are. Counters 264 and 266 are equivalent to the counters discussed above 5 and 6 and denoted by blocks 108, 124 and 132 are. At the time the control arrangement is triggered, each of these counters is set to one Pre-set count value equal to the number of sensor input signals ATCX1 to AOTC (15 in the present embodiment).

Before carrying out a work description of the controller of Fig. 11a to 11d (and FIGS. 11a 'to 11e') it is first considered to be advantageous briefly the operation of a two-bit delay counter 268, a sample counter 270, a sampler 272 and an analog-to-digital converter 247. Each of these Elements is shown in Fig. 11a (and in Fig. 11a '). The two-bit delay counter 268 is a conventional binary counter with set (S), reset (R) and trigger (T) input connections for generating three sequentially delayed outputs signals DLCO, DLC1 and DLC2 The time relationship between these signals is shown in the Figures 12a and 12b are shown. The DLC2 signal from counter 268 is fed to sample counter 270 supplied to an INC input terminal to increase this counter each time by the word 1 to increase when the analog-to-digital converter 274 does a conversion of one of the sensor input signals ATCX1 through AOTC on conductors 48 starts. As can be seen, the sample counter delivers 270 a plurality of sample counter outputs SCOO through SC14 on the conductors 276 to the conventional scanner 272 (scanner) to cause this element. that the Sonsoreingangasignale according to the respective counter content in the Sampling counter 270 sequentially samples or selects.

At the start of every analog / digital conversion, the DLC2 signal becomes dem A / D converter 247 is also supplied with a reset / start A / D signal. The reset / start A / D signal triggers the A / D converter 274 to start operating, and at the same time it causes that an A / D COMP signal on conductor 278 goes to a binary 0, as shown in FIG. 12 is shown. If the A / D-COMP signal is a binary 0, will this signal as a binary 1 through an inverter input terminal of an AND gate 280 continued. The AND gate 280 is triggered when the first CLK signal that follows the A / D-COMP signal, a reset signal is applied to this gate to run the R terminal of counter 268. This causes the generation of a DLCO signal at the time shown in Figures 12a and 12b. With completion of the analog / digital conversion (analog to digital conversion) the A / D-COMP signal goes to a binary 1, and this one Signal provides a set input signal to the S input terminal of the delay counter 268.

As shown in Figures 11a (and 11a '), 12a and 12b, the Counter 268 then triggered by the A / D-COMP signal with the binary 1, to the DLC1- and to generate DLC2 signals as a function of the two CLK signals associated with the T terminal of the counter 268 are supplied. As already explained, the sample counter is 270 Each time the DLC2 signal is generated, increased in value to cause that the scanner or scanner sequentially selects the next sensor input signal and at the same time resets the A / D converter 274 and starts. The ones just described Functions are used for each A / D conversion that the controller does for the various sensor input base ATCX1 to AOTC executes, repeatedly.

It is now assumed that the control arrangement has been triggered, and that the controller has just completed an analog / digital conversion of the ATCX1 signal. As shown in Figure 12a, the sample counter 270 is in binary O state, it therefore generates an SC00 signal with bin. Value 1, which causes the Sampler 272 selects the ATCX1 signal as shown in Figures 11a and 11a '. The A / D; converter 274 is also able to provide an output signal Generate OV + UV on a conductor 282. The A / D converter 274, which is a conventional Structure, generates an output signal with a binary on conductor 282 1 if it perceives either an overflow or an underflow condition. The OV + UV signal on conductor 282 for such a perceived overflow or underflow condition be distinctive.

During normal operation, the OV + UV signal remains on a binary 0 if the sensor generating the selected ATCK1 to AOTC signal is not interrupted or is provided with a short circuit. As shown in Fig. 11a, the OV + UV signal on conductor 282 to an inverter input terminal of an AND gate 284 in conjunction with the A / D-COMP signal. It can be seen that that AND gate 284 is triggered and a set input signal with a binary 1 is sent to the S-terminal of a good flip-flop # 1 ", 286 is fed when the A / D converter 274 does not perceive an overflow or underflow condition. the timing for setting and resetting flip-flop 286 is shown in phantom in Figures 12a and 12b shown. The dashed lines indicate that the flip-flop 286 is in the set State wants to go if there is no overflow or underflow state, otherwise the flip-flop 286 remains reset. Note that flip-flop 286 always is reset by the DLC2 signal from delay counter 268 when a Analog / digital conversion is started.

Assume that the "good flip-flop, # 1", 286 rolled into one is set state. This flip-flop generates an output signal with a binary 1 on a 1 terminal connected via conductor 288 to a trip input terminal EN a switch # 1, 290 and applied as an input to an AND gate 292. The switch 290 also receives over a plurality of conductors 294 from the A / D converter sensor data converted into digital form. When the switch 290 is now in operation is set (is triggered), the sensor data are then switched on via switch 290 given the input of a conventional adder before Peralleltyp, the adder ## 1, 296. The Addioror 296 is now by an ADD signal on a Conductor 298 triggered by AND gate 292, the AND gate being triggered by the A / D COMP signal is actuated or triggered on conductor 276 by A / D converter 274. The production of the ADD signal on conductor 298 is shown in dashed lines in FIGS. 12a to 12b Lines are shown indicating that the signal is only generated when the flip-flop 286 is set.

If the flip-flop 286 is not set, this is an invalid condition of the sensor monitored by the A / D converter, the adder 296 becomes Execution of the adding function not triggered.

It is now assumed that adder 296 has triggered and its Perform adding function. As shown in Figures 11a (and 11a '), the adder 296 outputs signals on a plurality of conductors 300 to a conventional one Accumulator register 302, labeled ACC #, and receives inputs via a plurality of conductors 304 from the accumulator 302. It can be done in this way realize that everybody when the adder 296 must perform an adding function. the Contents of the accumulator 302 for the sensor data input signals from the so holder 290 is added and that the sum of this addition is returned to accumulator 302 is carried out.

It is mm on Figs. 11a, 11b (and also on Figs. 11a 'and 11b') and refer to the timing diagrams of Figures 12a and 12b. It should be noted that the ADD signal on conductor 298 also has a Auslössingengsansohluß EN one conventional single multiple reader circuits 306 is supplied.

The multiplexer 306 receives the sensor data from the output of the switch 290. When the ADD signal is generated by gate 292, multiplexer 306 becomes placed in a position to transmit the sensor data via a plurality of conductors 308 into the upper To direct registers of a plurality of sensor data registers 310. The sensor data registers 310 preferably consist of registers of the reset stack principle (pushdown stack).

where the information entering the upper register upon activation the sensor data register sequentially down to the next by the DLC1 signal Register to be pushed.

With reference to FIGS. 12a and 12b, it can be seen that when blanking (gating) the register 310 by the DLC1 signal, the sensordosts can be entered into the sensor data register 310 while the sum is in the accumulator 302 is accumulated. At this time, the DLC1 signal becomes a set input terminal 5 of a 9bntordaten-Botrleban ip- £ lops SDU F / F, 312, as shown in the figure can be removed.

The flip-flop 312 is set at DLC1 time to show an STO1 signal a binary 1 on a conductor 314, as in the timing diagram of FIG. 12c and 12d shown imt. The StO1 signal is a trigger input terminal EN to a conventional output multiplexer circuit 376. The last register level the sensor data register 310 supplies sensor data via a plurality of conductors 318 to the input of the output multiplexer 316.

It can therefore be seen that the multiplexer 316 is triggered by the STO1 signal is enabled to receive the sensor data from the final output stage of the To pass registers 310 on a plurality of conductors 320.

The sensor data register 310 of FIGS. 11b (and of Fig. 11b ') is referred to. The number of registers 310 is equal to the number of the sensors or sensor input signals ATCX1 to AOTC (in the present embodiment 15). 15 A / D conversions are required before the sensor data register 310 are all filled with digital data for the temperature values of the corresponding ATCX1 through AOTC signals are indicative. It should also be noted that at the beginning For each new scan by the scanner 272 the ATCX1 = sensor signal is the first signal entering sensor data registers 310.

After 15 A / D conversions, the ATCX1 signal content is in the last output register the register 310.

It is also important at this point to note that any Sensor input signal. that is perceived as either interrupted or short-circuited state and an invalid sensor state indicates the generation of the ADD signal on conductor 298 is prevented.

As a result, the single multiplexer 306 is not triggered, and binary values then run into the upper register of the sensor data register 310 for this particular sensor. As a result, registers 310 always contain representations of the words only from the sensor readings ATCX1 through AOTC that are considered valid will. All invalid states are stored in the registers containing the sensor signals entaprechen, held as binary O values.

In order to operate the in fig. 11b and 11d (fig. 11b ', 11d' and 11e ' for the second form of this embodiment) to understand the logic illustrated it is now considered advantageous to return to the A / D converter 274 of FIGS 11a ') to refer to. The A / D-COMP and OV + US output signals from converter 274 will be led via conductors 278 and 282 to an AND gate 322. The output signal of the AND-fors 322 represents an acceptance signal DEC, which the "number of good read values counter # 1.264 is fed to this counter every time the A / D converter does either senses an overflow or underflow condition resulting from an invalid sensor reading stems from decreasing in his counting word. Since the counter 264 is constantly at the beginning Each sample is preceded, it always contains a counter value, which the number of the good or non-rejected readings that are received by the A / D converter 274 are perceived.

Signals that characterize the number of good readings in counter 264, are connected via a plurality of conductors 324 to a conventional divider circuit 326 supplied, which is denoted as a divider od. Te / ilér # ba. The divider 326 receives also signals over a plurality of conductors 328 representing the accumulated sum in the Identify accumulator 302 When divider 326 is activated, a divide function must perform, it divides the number of good readings on conductors 324 into the accumulated sum from accumulator gate 302.

The result of this division is the calculated mean Temperature expressed as a TXAVaN signal from the output of divider 326 on a multitude of ladders 330 is shown.

The dividing operation is carried out by a start signal 1 # 7, with DVD triggered, which is an input terminal EN of the divider 326 via a conductor 332 of a 1 output of a START DVD flip-flop ## 1, 334. Of Flip-flop 334 is activated by a START-DVD signal with the binary word 1 set, that comes from the output of an AND gate 336. Referring to Figs. 12c and 12d it can be seen that AND gate 336 is triggered when the two-bit pre-delay counter 268 generates a DLC2 signal and a sample number decoding a zero signal SCDO of the sampler count value decoding with a binary value 1 is generated. The decoding network 338 receives the SCOO through SC14 signals over a plurality of conductors 340 from the scanner counter 270

As shown in Figures 12b and 12d, the sampler generates count value decoding 338 the SCDO signal to trigger the AND gate 336 at the time DLC2 and thus the START DVD signal whenever the scanner counter 270 reaches counter word zero. That first CLK signal which is a T terminal of flip-flop 334 following the generation of the START-DVD signal is supplied, the flip-flop 334 sets a START-DVD1 signal is generated with the binary value 1 on a conductor 332. When the START-DVD1 signal is applied to divider 325, the number of good reading signals is increased conductor 324, and the accumulated sum on conductors 328 in divisor or Divider 326 where these signals are clocked in internal registers not shown are to be saved.

The CLX signal applied to divider 326 controls timing this circuit by performing the divide function.

The divider generates a DVD1-COMP signal upon completion of the dividing operation with a binary value of 1 on conductor 342. The DVD1-COMP signal becomes a reset circuit R is supplied to the flip-flop 334, whereby the flip-flop is reset. The length of time to carry out the division can be variable, and as long as until the divide operation is completed before the next SCOO signal is generated. The DVD1-COMP signal is also applied to a TXAVGM register 344 which contains the calculated average T @@ permtur TXAVGN- receives at the time that the DVD1-COMP signal is generated In addition, the DVD1-Comp signal is fed to a conventional adding latch 346 which, see FIG. 12d, algebraically represent the calculated mean temperature $ TXAVGN to a temperature deviation limit value or word LTXDF2 for the lower limit added from an LTXDF2 reference source 348. The DVD1 COMP signal is a pulse with the binary value 1, which has a duration of approximately one CLK period, which is long enough for adder 346 to perform the addition of signals LTXDF2 and TXAVGN can perform.

When the DVD1 COMP returns to a binary o, it becomes Signal through inverter 350, Fig. 11c (and 11c ') to a binary 1, i.e. to a signal DVD1 .Ip inverted. When the DVD1 COMP signal goes to a binary 1, the contents of the adder circuit 346 are converted into one via a plurality of conductors 354 Register 352 for the lower limit value clocked. The contents of register 352 for the lower limit represents the maximum lower limit of the calculated mean This below threshold is used as an output signal reference value on a plurality of conductors 356 provided by register 352 The lower one Threshold on conductors 356 is fed to a conventional subtrab circuit 358. This Subtrahlererschalt.356 also receives the sensor data output signal from Multiplexer 316 via the conductor 320 as a sensor 'signals, It it should be noted at this point that the dividing operation just described performed only once during the full cycle of the scanner 272 will. Each time the sample number decoding 338 of FIG. 11c receives a counter content decoded from 0 (SCDO = binary 1), which marks the beginning of a new scan the START DVD signal is generated. The START DVD signal is also transmitted via the OR gate 258 fed to the delaying monostable multivibrator 260, the one delayed output pulse generated to counter # 1 for the number of good read values, 262 (also referred to as "number of good read values counter # 1") to that noted in FIG. 12c Time to advance. The counter 264 is therefore always at the beginning of each new scan set to the correct value.

In addition, the register 352 contains constant for the lower limit value the lower limit resulting from each divide operation. As such, can the contents of register 352 only once during each scan of the sensor input signals ATCX1 to AOTC can be changed.

The purpose of subtracting circuit 358 (Figs. 1d and 11d ') is therein, the respective ATCX @ - to AOTC learning values from the lower reference limit value, which has just been described to be deducted to avoid possible combustion problems in the Perceive the turbine. The operation of subtract circuit 358 can be best be understood when reference is first made to a zero decode 360, which receives the SENSOR DATA 'signals on conductors 320 from multiplexer 316. the Decode 360 is of conventional construction and continuously monitors the output of the Multiplexer 316 to see if any the ATCX1 through AOTC reading is a binary 0, indicating a rejected temperature sensor is shown. Under normal conditions, i.e. when a sensor is not rejected the input signals on conductors 320 for decoding 360 are always indicative for a non-zero value. As long as the decoder 360 has a zero input signal decoded on conductors 320 is a zero output with the binary word 1 present on a conductor 362. The zero signal is used in conjunction with the previously SDO1 signals mentioned above are fed from flip-flop 312 to an AND gate 364, as in FIG As shown in Figures 12c and 12d, AND gate 364 generates a subtraction trigger signal SUBEN with the binary value 1 each time the SDU1 signal changes to a binary 1 and the zero decode output signal is a binary 1. When the SUBEN signal is on a binary 1 goes, the signal is sent as a trigger input signal to an input terminal EN is supplied to the subtracting circuit 358 to perform the aforementioned subtraction. Provided that the subtraction of any of the ATCX1 through AOTC signals from the lower limit value leads to an overflow condition in the subtraction hold, a limit violation signal with the binary value 1 on a conductor 366. The limit violation signal is combined in an AND gate 368 with the DLCO signal to activate this AND gate during to trigger a limit condition, thereby generating a signal with the binary To generate value 1 and to supply an OR gate 370. Of the OR-for 370, every @ mel triggered when a limit condition occurs, u a De Krementsignal DC 'with the binary value tin 1 a second number of good readings-count # 2: 266, to be fed to this counter for each orenz exceedance condition that is determined by the Subtracting circuit 358 is sensed to decrease the count one. The DEC 'signal appears on a ladder 371.

The output signal of the AND gate 364 of FIG. Reference is made to 11b (and also to FIG. 11b ').

As mentioned earlier, the output of the AND gate sets below normal Operating conditions represent a binary 1 to generate the SUBEN signal. It should be noted that the signal SUBEN is inverted by an inverter input terminal which is to an AND gate 372, the AND gate 372 also carrying the SDO1 and DLCO signals receives. Every @ times when the zero decoding 360 receives a binary O value from the multiplexer 316 is decoded, the AND gate 364 is disabled and generated a binary 0 signal on the SUBEN line. This signal is converted into a binary 1 inverted, in this way to trigger the AND-Ter 372 at the point in time which is characterized in FIGS. 12c and 12d by the generation of the DEC 'signal is.

In other words, whenever there is a zero through the Dekodieruq 360 is decoded, which indicates that the corresponding to the decoded reading value If the sensor is a declined sensor at this time, the counter content will be of the counter 266. decreases the value 1. This reduction is in this vell of the output of the UMD gate 372, which puts the OR gate 370 in the position to generate the DBC 'sigmel with a binary word 1 s.

It can be verified that the counter 266 is always a counter content that indicates the number of good readings caused by the rejection of the invalid sensors is determined during the A / D conversion process, and the also determined by those @beanne sensors will the while the subtraction circuit 358 executes the subtraction process Provide cross-limit reading.

Reference is now made to FIG. 11b (and FIG. 11b '), in which a Inverter input terminal of AND gate 374 the orenz exceeded signal on the Head 366 inherits. AND gate 374 also receives the DLCO and SDO signals.

With the completion of a subtraction operation, the binary O-signel on the conductor 366 inverted into a binary 1 by the inverter of the AND gate @ 374, unless there is a requirement to cross borders. and it gets to this Way enables this gate to be triggered when the DLCO and SD01 signals occur and a "good" flip-flop 82, 376, to that shown in Figures 12a through 12d Time to put. The setting of the flip-flop 376 also provides an output signal ADD ' a binary value of 1 on conductor 378 to the trigger input terminal EN of a switch # 2, 380, and to a triggered input terminal GN of an adder # 2, 382. The Switch 380 also receives the SENSOR DATA 'signals on conductors 320 and conducts this data in dependence on the ADD 'signal in the adder 382. The operation of switch 380 and adder 382 is the same as for switch 290 before and adder 296. The adder 382 provides data on a plurality from conductors 348 to an accumulator ACC # 2, 386, and receives data therefrom Accumulator over a plurality of conductors 388. The accumulator 386 operates in in the same way as described for the accumulator 302 to generate detection signals SUM 'to a divider # 2, 394 on a plurality of conductors 390 to be supplied. That good flip-flop # 2, 376, is driven by the SDO and DLC1 signals reset, which are fed to an AND gate 392, which has a signal with the binary A value of 1 is supplied to a reset input terminal R of the flip-flop 376 to enable the operation of adder 382 at the time indicated in Figures 12c and 12d.

In Figure 11b (and in Figure 11b ') the divider is operating # 2, 394, in the same way as the divider or divider previously described 326 of Fig. 11a (and Fig. 11a '). The divider 394 receives a number of good ones Read signals over a plurality of conductors 396 of which the number of good reads counting counter # 2, 266. Divider 394 divides the number of good reads into the SUM 'value to produce the final calculated mean output temperature signal TXAVG on a variety of conductors 398. The divider 394 is through a signal START DVD R2 is put into operation, which is generated by a START DVD flip-flop # 2, 400, has been applied to a release input terminal EN, see Fig. 11d (or Fig. 11d ').

The flip-flop 400 is enabled from the previous indicated START DVD signal from the output of AND gate 336 of Fig. 11c (and the Fig. 11c ') can be set, and it is set when the CLK signal is at its Trigger input connection T is applied. The flip-flop 400 is activated by a signal DVD2 COMP with a binary value of 1 coming from divider 394 via conductor 402, reset upon completion of the divide operation.

The description of this third embodiment of the invention is identical for both forms of this embodiment up to this point. The fig. 11a to 11c and a large part of Fig. 11d are associated with the corresponding Fig. 11a ' until 11d 'identical. Differences between the two forms occur Now then on, and there will now be a focus on the first and more fundamental Form considered sufficient.

The DVD2 COMP signal is also provided to a TXAVG REG 404 and a trigger input port EN fed to a second subtracting circuit 406. As in the timing diagram As shown in Figure 12d, the DVD2 COMP signal clocks the TLAVG signals into the register 404 and into subtracting circuit 406 for the subtraction of signal TXAVG from to trigger the basic temperature reference value TBASE. The rain limit value TBASE becomes the Subtract circuit 406 through a plurality of conductors 410 from a temperature base reference circuit TBASE REF 408 supplied.

As shown in Fig. 11d, the output of the subtracting circuit represents 406, the temperature compensation signal KVAL1 ', which via the conductors 412 to an output register 414 is supplied. The KVAL1 'signals are combined with a signal DVD2 COMP with the binary value 1 clocked by an inverter 416 into the run-out register 414, if the signal DVD2 C (MP at the end of the divide operation goes to a binary 0.

The output of register 414 is provided over a plurality of conductors 418 is fed to a conventional digital / analog converter (D / A) 420, which generates the calculated digital fuel control values into an analog value for supply to a conventional one Integration amplifier 422 converts. The output of amplifier 422 is that Temperature compensation signal BTMTEM. This signal runs as shown in Fig 1, en the analog temperature re @ ervesohutzeinrichtungen 36 over (bypass) and is as temperature fuel control signal TFC to the low value gate 34 fed.

The signal level output that characterizes the number of good read values of the counter 266 of FIG. 11b, a "number of good reads <8 decoding logic @ 426 supplied. The decoding logic 426 operates in the same In a manner like the previously described decoding logic 236 of FIG. 9b. Whenever the number the good reading in counter 266 is less than 8, the decoding logic 426 generates an output of binary 1 to AND gate 428. AND gate 428 receives also the DEVD2 COMP signal from inverter 416. As before in the previous embodiments described, it is considered necessary to shut down the turbine when the number of good readings is less than 8. When the DVD2 COMP signal is at a binary value of 1 goes, and if the output of the decoding logic 426 is a binary 1, the AND gate 428 is generally set to a signal RESET INT with a supply binary @ value 1 to integrator 422, which causes the TFC signal to zero is graduated and in this way the fuel supply to the turbine is stopped.

Reference is now made to FIG. 13, which in a schematic Logic form shows a version of the embodiment of FIGS. 11a to 11d. In Fig. 13 are parts of the digital controller of Fig lId for reasons of simplicity and for better understanding. These duplicated components are the inverter 416, the Subtrahlersoheltung 406, the number of good read values> 8 decoding logic " 426, AND gate 428, output register 414, integrator amplifier 422 and the D / A converter 420, the one added to the regler in FIG component consists of an algebraic summer 430 connected to a positive input terminal (+) the calculated temperature compensation signal, labeled KVAL1, from the D / A converter 420 receives. The summing circuit receives at a negative input terminal (1) 430 also the BTMTEM signal from the output of the integration amplifier 422. The integrator 422 and summer 430 generate the BTMTEM signal in the same manner as previously described in connection with FIG.

FIG. 13 also shows a modified form of the analog temperature reserve protection device 36, which was previously described in connection with FIGS. 1 and 2.

The analog temperature reserve protection device according to FIG. 13 contains same reference numerals provided with a prime for the corresponding, previously components described in connection with FIGS. For example, the mean value voter 64 of Figure 2 shown as 64 '. The analog backup protection device 36 'of FIG. 13 is basically the same as that previously used in connection with Fig. 2 described device with the exception that an A / D converter 432 and a ATXDD holding register 434 is inserted. In the embodiment of FIG. 13 monitored the selector 64 'continuously receives the AOTA through AOTC turbine sensor signals as before is described to generate the analog mean value signal, the ATXDA signal and is fed to the input of the A / D converter 432. The A / D converter 432 operates similarly to A / D converter 274 described in connection with Figure 11a became. Converter 432 receives the CLK clock signals from generator 250 and the signal START DVD from the output of AND gate 336 of Figure 11c to reset this converter and to start when the signal START DVD to a binary value 1 goes. When an A / D conversion is completed, the output signal of the converter is 432 a digital value that identifies the mean value signal that is based on a variety of conductors appears as ATXDD signals. The ATXDD signals are sent to the input of the ATXDD holding register 434 supplied. At the end of a division by the divider 394, the DVD2 COMP signal on conductor 402 transitions to a binary 1 representing the Gates ATXDD signals into register 434. At this point, the content of the Registers 434 as signals ATXDD 'on a plurality of conductors through the signal DVD2 COMP is gated into the subtracting circuit 406. In this embodiment of the controller (FIG. 13), the subtracting circuit 406 forms the difference between the mean value signal ATXDD 'and the calculated mean temperature TXAVG. In a manner previously described, the content of the subtracting circuit 406 is through the signal DVD2 in into the output register 414 for input to the D / A converter 420 clocked. The D / A converter 420 supplies the calculated adjustment signal KVAL1 to the positive input terminal (+) of summing circuit 430. The purpose for the feedback of the BTMTEM signal from the output of amplifier 422 back to the negative input terminal (-) of the slimming member 430 is the same as previously in connection with FIG. 10 has been described.

The analog temperature reserve protection device 36 'is now Referenced. It is shown that the ATXfl signal in connection with the ATREF'- and the BTMTEM signal is fed to summer 66 'to generate the temporal fuel gate control signal To pass TFC through amplifier 68 'as previously described in connection with FIG became. The output signal is used in normal operation TFC's Amplifier 68 'on conductor 58 the algebraic sum of the ATXDA, ATREF' - and BTMTEM signals. However, if the number of good readings is less than 8, as is decoded by the decoding logic 426, the AND gate 428 is triggered, to generate a RESET INT signal to reset integrator 422, thereby the output signal BTMTEM is stepped to the value zero. When this happens, it takes over the analog reserve protection device 36 'operates in the manner already described, to route the TFC signal to the turbine via low gate 34. In the latter Case, the value of the TFC signal is indicative of the algebraic sum of the ATXD & - and ATREF 'signals, since the BTMTEM signal is now an ineffective value owns.

The timing for the embodiment of FIG. 13 is shown in FIGS. 12a to 12d not presented in their entirety; by observing the signals, those present in these figures for generating the signals START DVD and DVD2 COMP however, the operation of Fig. 13 can be easily understood.

Consider now the second form of the third embodiment. The common description of the first and second forms of this third embodiment ended with the generation of the TXAVG signal from divider 394 (Fig. 11b ') and the Appearance of this signal on conductors 398.

As before with reference to the first form of this embodiment but now referring to Figure 11b 'is divided the divider 394 the number of good readings in the SUM 'value in order to get the final, calculated Generate mean output temperature signal TXAVG on a plurality of conductors 398. The divider 394 is activated by a signal START DVD # 2 which a trigger input terminal EN of a START DVD flip-flop # 2, 400, of Fig. 11d ' is fed. The flip-flop 400 is triggered by the previously described Signal START DVD from the output of AND gate 336 of Fig. 11e 'to be asserted, and it is set when the CLK signal is applied to the trigger input terminal T of the flip-flop 400 is created. The flip-flop 400 is activated by a signal DVD2 COMP with the binary Value 1 from divider 394 through conductor 402 upon completion of the divide operation reset.

The signal DVD2 COMP is also sent to a TXAVG REG 404 and a triggering signal connection a second subtracting circuit 406 of the fil. 113 'is supplied. As in the timing diagram As shown in Figure 12d, the DVD2 COMP signal clocks the TXAVG signals into the register 404 and into subtraction circuit 406 to perform subtraction of the TXAVG signal from of the basic temperature reference value TBAS. The reference value TBASE is taken from a basic temperature reference circuit TBASE HEF 406 via a multitude of conductors 410 is fed to the subtracting circuit 406.

As can be seen from Fig. 11e ', the results of the subtraction are by a signal DVD2 COMP from an inverter 416 into a KVAL2 latch 413 gated.

The signal DVD2 COMP goes to a binary 1 when the signal DVD2 COMP goes to a binary 0 as shown in Figure 12d.

The register 413 now contains the calculated correction value KVAL2. This value is in digital form all of a variety of conductors as the KVAL2 signal a digital / analog converter 415 is supplied.

The converter 415 converts the KVAL2 signal into an analog signal KVAL2 ' um, the latter signal having two comparator circuits KVAL2 '<0, 417, and KVAL2' > 0, 419, is supplied. Each of the comparators 417 and 419 also receives a yeast signal from a Mull reference source 421 for comparison with that KVAL2 'signal. When the KVAL2 'signal is less than the reference value (O), the comparator 417 energizes to a trip signal with the binary value 1 as an input signal to an AND gate 423 via a conductor 425 to lead. Similarly, it delivers the comparator 419 sends a signal with a binary 1 to the input of a second AND gate 427 through a conductor 429 when the KVAL2 'signal is greater than the reference value. As long as the value of KVAL2 'is equal to the reference value (O), the Output signals from the two comparators on conductors 425 and 429 in a binary State and prevent the triggering of both AND gates 423 or 427. This state is present if there is no difference between the base temperature (TBASE) and the calculated mean temperature (TXAVG) is present. Unless there is any difference between these signals (positive or negative) is generated by the appropriate comparator of the comparators 417 or 419 a signal with a binary 1.

It is now on the decelerating monostable multivibrator os 431 11e ', which receives the signal uvWuwir from the inverter 416 of FIG. 11d ' receives. The monostable multivibrator 431 produces a sufficient Delay in order for the signals on conductors 425 and 429 to be passed by the D / A converter derive from the KVAL2 signals and a comparison of the KVAL2 'signal let before the output signal of the monostable multivibrator 431 a second Input of AND gates 423 and 427 is supplied.

When the monostable multivibrator 431 sends a pulse with a binary 1 feeds gates 423 and 427, the gate that has a binary 1 signal on a the conductor 425 or 429 is supplied, triggered. Unless none of the comparators 417 or 419 generates a binary 1 signal, none of the AND gates are triggered by the output pulse triggered by the monostable multivibrator 431.

It should be noted that the outputs of AND gates 423 and 427 den DEC (decrement) and INC (increment) input terminals of an up / down counter (KVALR2 REG) 437 can be fed in via conductors 433 or 435.

The KVALR2 register 437 is reset by a system reset signal upon system start-up is reset to zero on conductor 256 so that KVALR2 always starts from zero or count down. If the value of KVAL2 'is greater than the reference value (zero) is, the AND gate 427 is triggered when the monostable multivibrator 431 is triggered is to send an incremental signal with a binary value 1 to the KVALR2 register on the Feed conductor 435. If, on the other hand, the value of KVAL2 'is less than the reference value, so the AND gate 423 is triggered to a decrement signal with a binary value 1 to the KVALR2 register.

Initiate the increment and document signals to the KVALR2 register, that the count in this register has increased by one Fine adjustment constant is increased or decreased as specified by the manufacturer's choice will.

In the preferred embodiment, the value of KVALR2 is given by a fine tuning constant or a count of 1 for each incremental or decrement signal which is fed to the KVALR2 register. It can therefore be seen that upon completion of each division operations by the controller of FIGS. 11a 'to 11e 'the value of KVALR2 according to the difference between the values of the TBASE and the TXAVG signals is set or not set.

The output of the KVALR2 register is in digital form over several Conductor 439 is fed to a digital / analog converter 441. The converter 441 converts the digital values from register 437 into equivalent analog signals KVALR2 on a wire 443 um. The KVALR2 signal is fed to a conventional integration amplifier 445, which has an integrated output signal KVALR2 'to a positive input terminal a summing member 447 via a conductor 449 supplies.

The XVALR2 signal from the converter 441 is also sent to one input of the two conventional comparator circuits 451 and 453 via a conductor 443 and a Head 455 fed.

The comparators 451 and 453 further receive respective ones Input terminals a + LKVAL2- and a -LXVAL2 reference limit value signal of corresponding Reference sources 457 and 459. The purpose of comparators 451 and 453 is to the absolute value of KVALR2 with corresponding positive and negative reference limits Compare + LKVAL2 and -LAVAL2.

When the value of KVALR2 is within the range indicated by the LKVAL2 and LKVAL2 signals specified limit values, the output signal of both comparators is 451 and 453 a binary 0. These output signals are fed to an ODRR gate 461. If the value of KVALR2 exceeds one of the limit values + or - LXVAL2, takes the corresponding comparator is true and returns a limit crossing condition a trip signal with a binary value 1 to the OR gate 461. If the OR gate 461 is triggered, it generates a binary 1 signal that can be used to an alarm for the purposes previously described in connection with FIGS. 9a 'and 9b' @ to solve.

It is now referred to the analog Resorvoschutzeinrichtuq 36 'of Fig. 11o' Referring to it, a signal ATXDo 'with medium value in digital form on a A plurality of conductors 463 are generated. The ATXDD 'signals become conventional Subtraction circuit 465 which also carries the TXAVG signals on the conductors 467 receives. The subtracting circuit 465 is enabled to use the TXAVG value of the ATXDD 'value as a function of the DVB2 COMP signal with a binary value 1 to subtract, the DVD2 COMP signal to the Auslöme @ ingangmensohluß BN is applied at the time shown in Fig. 12d.

The very precisely calculated mean turbine temperature (TXAVG) becomes from ATXDD '(medium value signal), which is approximately equal to the mean turbine temperature is subtracted to give the expected differences between these two values obtain. The subtraction results in a second correction value in the form of digital Signals on a variety of conductors 469.

The signals on conductors 469 are represented by the DVD2 COMP with the binary value 1 from the inverter 416 into an output register 471.

The output of register 471 is a variety of Conductors 418 to a conventional digital-to-analog converter (D / A) 420 as a correction value KVAL1 supplied. The converter 420 converts the KVAL1 signals into an analog signal KVAL1 'to be fed to a positive terminal of a sum 473.

The output of the summer 473 is a conventional one Integrating amplifier 422 is supplied, which has an integrated fuel correction signal KVALR1 is generated and on a conductor 475 to an input terminal of the summing element 447 leads. The KVALR1 and KVALR2 'signals become algebraic in summer 447 combined with the DELR1 signal on conductor 477 to produce the temperature trim signal BTMTEM on conductor 52 to generate.

The delta reference signal DELH1 is generated by a signaling element 479, the ATREF signal (safe temperature reference signal) and a TBASE 'signal which has a value proportional to the bottom temperature of the turbine or the set point. As previously described, the DELR1 signal has a value which is proportional to the difference between the ATREF and TBASE 'signals and serves as a temperature setpoint reference to maintain the turbine temperature on one desired. Value.

The TBASE 'signal is analog in nature and is generated by a Digital / analog converter (D / A) 48 'generated, which converts the digital signals TBASE to the Ladders 410 from the TBASE REF- Source 408 converts.

The BTMTEM signal is in the analog reserve protection device 36 ' combined with the ATXDD and ATREF signals to produce the temperature fuel control signal TFC on conductor 58 which is fed to low gate 34 of FIG will.

The KVALR1 signal from amplifier 422 becomes a negative input terminal of the summer 473 is fed back, where the signal with the KVAL1 'signal to the same Purpose previously described in connection with amplifier 257 of Fig. 9b ', is combined.

The signals from the Output of counter 266 of FIG. 11b 'is provided via conductor 424 to a "number of good." Read values <8 decoding logic "426 of FIG. 11d '. The decoding logic 426 operates like decode logic 236 of Figure 9b 'previously described. if the number of good read values in counter 266 is less than 8, the decoding logic generates 426 an output signal with a binary value 1 and supplies this signal to AND gate 428. AND gate 428 receives signal DVD2COMP from inverter 416. How previously explained in the above embodiments, it is considered necessary the turbine under the control and regulation of the analog reserve protection device if the number of good readings is less than 8. When the signal ! WI> 2COKP goes to a binary value 1, and if the output of the decoding logic 426 is a binary 1, AND gate 428 is triggered and provides a RESET signal INT with a binary value 1 to integrators 422 and 445, causing the BTMTEM signal to be stepped to zero, thereby reducing the TFC signal takes on the value of the algebraic sum of the ATREF and ATXDD signals.

Reference is now made to FIG. 14 which shows a modified form the analog temperature rose protector 36 'for use in the embodiment of Figures 11a 'to 11e' shows. The analog temperature reserve protection device 14 has the same primed reference numerals for those Components similar to those previously described in connection with FIGS. 1 and 2 Components correspond. For example, the mean selector 64 of Fig. 2 is in 14 denoted by 64 '. The analog backup protection device 36 of FIG. 14 is in its basic structure with that previously described in connection with FIG Setup is identical except that an analog-to-digital converter 432 and a ATXDD holding register 434 is connected. Monitored in the embodiment according to FIG the selector 64 'continuously receives the AOTA through AOTC turbine sensor signals as before has been explained to produce an analog signal of medium value, which is called ATXDA signal is fed to the input of the analog / digital converter 432. The analog / digital converter 432 works similarly to the analog / digital converter described in connection with FIG. 11a ' 274. Converter 432 receives the CLK clock property from generator 250 and the signal START DVD from the output of AND gate 336 of Figure 11c 'to reset the converter and to start when the START DVD signal goes to a binary 1.

When an analog / digital conversion is completed, the output signal is of converter 432, a digital value identifying the middle word signal and on a variety of ladders 436 shown as ATXDD signals is. The ATXDD signals are applied to the input of the ATXDD holding register 434.

Upon completion of division by divider 394, the signal goes DVD2 COMP on conductor 402 to a binary value 1 and gates the ATXDD signals into register 434. At the same time, the contents of register 434 are used as signals ATXDD 'on conductors 463 by signal DVD2 COMP into the subtracter circuit 463 gated (cf.

Fig. 110 ').

Reference is still made to FIG. 14. The ATXDA signal becomes in connection with the ATREF 'and the BTMTEM signal fed to the summing element 66', to pass the temperature fuel regulator TFC through amplifier 68 ', as previously described in connection with FIG. In normal operation the output signal is TFC on conductor 58 from amplifier 68 'for the algebraic sum of the ATXDA, Characteristic of ATREF 'and BTMTEM signals. However, if the number of good readings is less than 8, as decoded by decoding logic 426, the AND gate becomes 428 is enabled to generate a signal REST INT to the integrators 422 and 445 reset, whereby the output signal BTMTEM downgraded to zero will. When this occurs, the backup analog protector 36 'in FIG the regulation described above and delivers the TFC signal via the low value gate 34 to the turbine. In the latter case, the value of the TFC signal is for the algebraic The sum of the ATXDA and ATREF 'signals is representative since the BTMTEM signal is now has an ineffective value.

The comparator and locking circuits for generating the fuel trigger signal on conductor 60 (Fig. 2) not shown in FIG. These circles have been omitted from Fig. 14 to simplify the drawing; it However, it should be noted that these circuits are connected to the output of the selector 64 'can be connected in the same way as shown in FIG.
