Description

The microprocessor relay protection and automation TEKON 300 (abbreviated as MP RPA device) is designed to protect the electrical equipment of power plants, substations, distribution networks and electrical energy distribution devices. The relay protection and automation device (hereinafter referred to as the device) can be used both as an independent device and as part of a software and hardware complex. The device measures and calculates the values of currents, voltages, resistances, power, energy, network frequency, as well as amplitudes, effective values, phases, symmetric and emergency components of the signals with the possibility of displaying them on the display of the display panel and with the possibility of transmission via communication channels. The device controls switching devices designed to automatically disconnect the controlled electrical equipment (object of protection) from the rest of the electrical network (electrical installation) in case of its electrical damage or emergency operation, which can lead to damage. The device is designed to work according to IEC 61850.

The term "connector" is used in the application in a general sense and covers instrument sockets and / or plugs (ports, connectors, clamps, etc.).

To describe the inventive device and its analogs, the side of the body on which is mounted or which is designed to mount the display and control panels, we take the "front" side of the body. The opposite side of the case, on which the RS-485, Ethernet 100Base-TX, Ethernet 100Base-FX interface connectors are located (hereinafter interface connectors), connectors for powering the device, connectors for inputting voltage and / or current signals from controlled electrical equipment and connectors for outputting signals, we take the "back" side of the case.

The terms “Ethernet-connector”, “Ethernet-cable”, “Ethernet-controller”, “Ethernet-bus” are used in the application with respect to the structural elements intended for data transmission via Ethernet technologies described by IEEE 802.3 standards.

The term “Ethernet communication” is used in the application with respect to data transmission (communication) over Ethernet technologies described by the IEEE 802.3 standards.

The term “RS-485 communication” is used in the application for communication, the electrical parameters of which are regulated by the RS-485 standard (EIA / TIA-485-A).

The term "communication channel" refers to a combination of technical devices (cables, connectors, printed circuit boards, etc.) that ensure the transmission of messages of any kind from the sender to the receiver, carried out using electrical signals.

To accommodate MP RPA devices, electrical cabinets are used, inside of which vertical elements are provided (swing frames, mounting panels, etc.). It is known that cabinets for relay protection and automation devices can be either unilateral or bilateral. Cases can be with survey (glass) doors or deaf (metal) doors with viewing windows.

Known modular relay protection device (hereinafter the device) (US patent No. 6259173 B1, patent holder of General Electric Company), adopted as an analogue for the first and second inventions. The device comprises a housing with a hinged display and control panel (hereinafter the panel). The panel is designed to control the device and display information about the status of the device and the object of protection. The panel provides access to the functional modules located in the housing. Each functional module (power supply module, transformer module, central processor module (CPU module), digital signal processor module (DSP module) and other modules) is installed in the housing using disconnect slots or rails. Each functional module is mechanically and electrically connected to the backplane and has pins for connecting to the corresponding terminal block, designed to be connected to external devices and mounted on the rear side of the case. When the panel is open, any functional module can be easily removed from the housing and replaced by a module that is similar in function to the module, without having to disconnect the terminal blocks from the device.

This modular design of the well-known device of the General Electric Company provides significant advantages over the fixed configuration of the analog input circuitry and discrete signal input / output circuitry. Replacing the modules makes it possible to quickly repair the device. The disadvantages of the known device include the fact that the panel and the housing with functional modules form a single design, which leads to a limitation of the placement of the device in the cabinet. To provide access to both the panel and the terminal blocks of the known device, it is necessary to use a double-sided cabinet.

A microprocessor relay protection device (hereinafter referred to as a device) with a modular control panel for indication and control (hereinafter referred to as a panel) is known (US patent No. 6169651 B1, patent holder of the General Electric Company), adopted as an analogue for the second invention. The device comprises a housing. In the case are the backplane and functional modules, including the central processor module. Each functional module can be removed from the housing from the side of the panel in order to replace a module similar in function or another in function. The panel consists of a main plastic frame, a printed circuit board with electronic components and a back cover. The main plastic frame is designed to place the keyboard, display and indicators on it. The panel can be fixed to the body using a hinge. In this case, the other side of the panel is connected to the housing using a latch. The panel can be removable. In this case, the panel is connected to the central processor module using a cable designed to exchange communication signals and supply power to the panel. The panel has a connector for connecting a personal computer (hereinafter PC) for downloading parameters, monitoring data and sequence of events. A separate panel, connected by a cable to the central processor module, allows you to mount the panel remotely and perform remote control and monitoring. In addition, a separate panel develops the concept of modular design of PM RPA devices. The disadvantages of the known device include the fact that you can only place such a device in a two-way service cabinet to provide access to terminal blocks and functional modules.

A digital protection and control device SIPROTEC 4 is known, the design of which is described in the following documents:

и 19''. Конструкция устройства SIPROTEC 4 предусматривает три типа исполнения: с панелью управления, закрепленной на корпусе, с отдельной панелью управления и без панели управления. Тип устройства определяется исходя из условий расположения устройства в шкафу или на монтажной панели.The digital protection and control device SIPROTEC 4 (hereinafter the device) is adopted as the closest analogue for the first and second variants of the invention. The device case has three sizes according to the Euromechanics standard:

,

and 19 ''. The SIPROTEC 4 device is designed in three types: with a control panel mounted on the housing, with a separate control panel and without a control panel. The type of device is determined based on the conditions of the device in the cabinet or on the mounting panel.

The first type of SIPROTEC 4 device with a control panel fixed on the body (hereinafter the panel) is designed for flush mounting on vertical cabinet elements (mounting panel or door). On the front side of the case there are corners to which the panel is mounted and which are used to mount the device on the vertical elements of the cabinet in case of flush mounting. Functional modules are located in the housing, including a central processor module (CPU module), input-output modules (I / O module), and a power module installed on one of the I / O modules. Interface modules are fixed on the CPU module board. The CPU module board contains interface connectors and a connector for connecting ribbon cables connecting the CPU module to the I / O modules and to the panel. A metal wall is screwed to the rear side of the housing with holes for connectors of functional modules. Terminal blocks are screwed to the wall for connection to external devices. SIPROTEC 4 can be controlled using the panel or using a PC with DIGSI installed on it. The PC can be connected to the 9-pin RS-232 or RS-485 interface connector on the panel.

The second type of SIPROTEC 4 device with a separate panel can be used for surface (surface) mounting of the device on the vertical elements of the cabinet. In this case, a separate panel can be fixed on the cabinet door, and a case with functional modules is fixed on the cabinet mounting panel. A PC can be connected to the panel connector. To connect to the power cable and connect a separate panel, there is a connector on the rear side of the case that is structurally different from other interface connectors, namely the 68-pin one. The design of the housing with the functional modules of such a device is similar to the housing with the functional modules of the device with a panel mounted on the housing. The design difference is that the front side of the case is closed by an additional front panel, made without a display and keyboard.

The third type of device SIPROTEC 4 - without a panel can be used for surface (surface) mounting of the device on the vertical elements of the cabinet. This type of device, as well as a device with a separate panel, contains an additional front panel, made without a display and keyboard. To connect a cable for communication with a PC, on the back of the case there is a connector different from other interface connectors, namely a 68-pin one. When you connect the communication cable to the PC, the device recognizes that it will be operated without a panel.

SIPROTEC 4 uses a variety of modular solutions that make it easy to use. The disadvantages of the device include the fact that to replace a failed function module or to replace an interface module, it is necessary to remove the device from the mounting panel and dismantle either the control panel or an additional front panel.

Similar to the SIPROTEC 4 device, the device types and methods for connecting the device to the panel are provided by the SIPROTEC 5 digital protection and automation system for power transmission networks (SIPROTEC 5 - System Overview. Protection, Automation and Monitoring, SIP 5.01, V1.0 Catalog, Hardware section on p. 26-29 and p. 45, release date 02.2011), adopted as an analogue for the second invention. The difference between the SIPROTEC 5 device and the SIPROTEC 4 device is that a PC with DIGSI5 installed is connected to the panel’s USB connector via a USB cable.

The objective of the invention is the creation of a relay protection device and automation design, convenient to use, repair and modernize under operating conditions and providing the possibility of assembling a relay protection device and automation with the necessary composition of functional modules.

и 19''. На боковых стенках корпуса 1 (фиг. 1) закреплены металлические уголки 2, предназначенные для жесткого крепления панели 3 к корпусу 1 и для крепления устройства в шкафу. С передней стороны корпуса расположен металлический экран 4 (фиг. 2), в котором выполнен вырез под первый соединитель 5 для панели 3. Экран 4 предназначен для механической защиты объединительной печатной платы 6 и электромагнитной защиты электронных компонентов печатных плат функциональных модулей, расположенных в корпусе.The metal case has three standard sizes according to the Euromechanics standard:

,

and 19 ''. On the side walls of the housing 1 (Fig. 1), metal corners 2 are fixed, which are used for rigidly attaching the panel 3 to the housing 1 and for mounting the device in a cabinet. On the front side of the case there is a metal screen 4 (Fig. 2), in which a cutout is made for the first connector 5 for the panel 3. Screen 4 is intended for mechanical protection of the backplane 6 and electromagnetic protection of the electronic components of the printed circuit boards of the functional modules located in the case.

The backplane printed circuit board 6 (Fig. 3) is mounted in the housing 1 parallel to the screen 4 and has connectors 7 for functional modules, a first connector 5 for panel 3 and a bus for transmitting digital signals of input and output circuits and a power bus for functional modules and panel 3. First connector 5 is for the first cable 8, through which power is supplied to panel 3 and RS-485 communication is performed.

The device contains the following functional modules:

- CPU module;

- power module;

- a signal input module, which can be made in the form of a module for input of analog signals from a controlled electrical equipment, or in the form of a module for input of discrete signals from a controlled electrical equipment.

- discrete signal output module.

The device may include discrete signal input / output module, which combines the functions of the discrete signal input module from the controlled electrical equipment and the functions of the discrete signal output module (hereinafter, the discrete signal input / output module).

The device is a composable product. The layout includes: types and number of input modules for signals, number of output modules for discrete signals, number of input / output modules for discrete signals, frame size, type and number of interfaces, types of communication protocols used, type of display and control panel (hereinafter panel) and type of display used panels. Depending on the functions performed, the device has 11 types. Depending on the composition of the modules intended for input and output signals, and the frame size of the case, the device has 14 hardware types.

In FIG. 1 shows one embodiment of a device with a case size

, the package of which includes the following functional modules: 9 - CPU module, 10 - power module, 11 - module for inputting analog signals from controlled electrical equipment, 12 - module for inputting discrete signals from controlled electric equipment, 13 - module for outputting discrete signals, 14 - input module - output of discrete signals.

The CPU module performs digital processing of input signals, implements protection algorithms and supports the exchange of information with external digital devices: PCs, ACS controllers, etc. The CPU module controls the operation of the remaining device modules via the bus on the backplane. The module occupies two seats in the housing.

The power module provides stabilized voltage to all nodes of the device in the operating range of changes in the voltage of the operating current. Two types of power module are used - with one input or two inputs. The device is powered from one or two power feeders: alternating (50 ± 5) Hz, direct or rectified current with a rated voltage of 220 V; DC with a rated voltage of 110 V; alternating (50 ± 5) Hz current with a rated voltage of 100 V. Moreover, the device functions correctly when the supply voltage of the operating current U _{min / max} changes from 65 to 264 V. The module occupies two seats in the housing. In FIG. 1 shows a device with a power module, which, in turn, has two identical power submodules, each of which has its own connector 15 and 16. These submodules constantly work in parallel, thus providing instant redistribution of the load from the damaged power submodule to a working one without loss time or restarting the power module, the same is true for the case of power failure at the input of any of the submodules. This embodiment of the power module increases the reliability of the device.

The input module of analog signals from controlled electrical equipment is designed to receive signals of alternating voltage and / or alternating current of industrial frequency. The module includes intermediate voltage transformers and / or intermediate current transformers (depending on the module version) and analog-to-digital converters. The analog signals are converted to a digital code and transmitted to the CPU module. The analog signal input module has eight channels with a nominal voltage value of 100 V and / or with a nominal current value of 1 A or 5 A. The module occupies two seats in the housing.

The module for inputting discrete signals from controlled electrical equipment occupies one seat in the housing.

The module for outputting discrete signals occupies one seat.

The digital input / output module includes 6 digital inputs and 6 digital outputs. Such a module occupies one seat.

All functional electronic modules of the device contain an end plate 18 (Fig. 4) and at least one printed circuit board with electronic components and connectors. The end plate 18 serves to fix the functional module in the housing and acts as a screen designed for mechanical and electromagnetic protection of the electronic components of the module.

Functional modules are located in the housing perpendicular to the backplane 6. Inside the housing, rails 19 for the functional module boards are located above and below. To fix the modules in the housing, metal rails 20 with holes are located on the top and bottom, to which the end plates 18 of the modules 18 are screwed. To remove the functional module from the housing, you only need to disconnect the terminal blocks with the cables for connecting external devices, unscrew the screws 21 and remove the functional module.

In FIG. 4 and FIG. Figure 5 shows the basic configuration of the CPU module (without additional interface modules), which has an RS-485 interface connector, a PPS synchronization connector, an Ethernet 100Base-TX interface connector 22, for connecting a PC, and a second connector 23 for panel 3. The second connector 23 for panel 3 is structurally different from other interface connectors of the device. This is to prevent the connection of a PC cable to this connector.

The design of the CPU module allows the installation of at least one interface module. Interface modules provide the device with additional network interfaces RS-485, Ethernet 100Base-TX, Ethernet 100Base-FX.

In FIG. 4 shows a variant of a CPU module with the possibility of placing two interface modules in it. For this, the CPU module contains a backplane 24 of the CPU module with connectors 26 for the printed circuit boards of the interface modules. The backplane 24 of the CPU module is used to supply power and exchange signals between the printed circuit board 25 of the CPU module and the printed circuit boards of the interface modules. Between the backplane 24 of the CPU module and the end plate 18 of the CPU module, guide rails 27 are provided for holding the interface module boards. In the end plate 18 of the CPU module, two non-circular holes are made, closed (in the absence of modules) with false plates identical in shape to the holes. When installing the interface module, the false plate is removed, the printed circuit board of the interface module is inserted into the guides 27 on the CPU module and the interface module is advanced into the backplane 24 of the CPU module until it stops. Installing and replacing one interface module with another is done without disassembling the device.

The device can be controlled in three ways: control from the panel; control from a laptop using tool software (hereinafter IPO); control from a remote PC via a serial communication channel using IPO. When controlled from the panel, user access to device functions is limited. IPO includes a number of software modules necessary to perform tasks related to configuration, parameterization (setting), monitoring the status of the device, viewing and downloading waveforms, obtaining current measurements, administering users and their rights.

Panel 3 (Fig. 7 and Fig. 8) is designed to control the device and display information about the status of the device and the object of protection. Between the front panel 28 and the cover 29 of the panel 3 is a printed circuit board with a connector 30 for the power cable and communication. On the front panel 28 there is a numeric keypad with a register of function keys, cursor buttons, control buttons of the switching device, alphanumeric or graphic display, and an LED display panel. Panel 3 has an Ethernet connector 31 for connecting a PC cable.

The design of the device provides for three types of execution: with a panel rigidly mounted on the housing (Fig. 1), with a separate panel (Fig. 9) and without a panel. The type of device is determined based on the conditions of the device in the cabinet or on the mounting panel.

In FIG. 10 is a schematic illustration of a CPU module board with connectors, electronic components, and power and / or communication buses, showing possible options for connecting a PC and a panel for three types of device design: with a panel mounted on the case, with a separate panel and without a panel.

It should be noted that the terms “panel mounted on the housing” and “panel located separately from the housing or a separate panel” reflect only the location of the display and control panel relative to the housing with functional modules. Unlike analogues - devices SIPROTEC 4 and SIPROTEC 5, in the claimed device, neither panel 3, nor case 1 with functional modules are subject to any design changes regardless of the type of device and no additional special products are required to place any type of device in a cabinet . For the power and communication of the panel 3, mounted on the housing, and the panel 3, located separately from the housing, the same cable can be used, but different cables can be used - the first cable 8 for power and communication and the second cable 32 for power and communication, as in the claimed device. Cables 8 and 32 differ only in length and type of connector used at the end of the cable, while the type and functionality of power and communication cables 8 and 32 are the same.

The first type of device with a panel 3 mounted on the housing is designed for flush mounting on the vertical elements of the cabinet (mounting panel or door). Use a two-way service cabinet to provide access to both panel 3 and functional modules.

In FIG. 10 schematically shows a panel 3 mounted on a housing 1 (the right side of the figure). The first cable 8 is located between the first connector 5 and connector 30 and is designed to supply power from the power module to panel 3 and RS-485 communication between the CPU module and panel 3. For the device described above, the first connector 5 is mounted on a backplane 6, whose buses used for power and communication between the CPU module, power module and the panel 3. The printed circuit board 25 of the CPU module contains: a digital signal processor (DSP) (not shown), a communication processor 33, an Ethernet controller 34, a jumper block 35, the first and second Ethernet tires 36 and 37 The communication processor 33 is designed to solve communication problems, diagnostics, data storage, program downloads. The first Ethernet communication channel between the communication processor 33 and the PC connected to the panel 3 includes: a bus between the communication processor 33 and the Ethernet controller 34, a bus between the Ethernet controller 34 and the jumper block 35, a first Ethernet bus 36, a backplane bus printed circuit board 6, the first cable 8, along which, in addition to power and RS-485 communication for panel 3, Ethernet communication is also provided for the PC, panel 3 PCB bus and PC communication cable. At the same time, the Ethernet communication channel passes by the processor of the panel 3, has no communication with it, and therefore does not load the processor of the panel 3.

The RS-485 communication channel between the communication processor 33 and the panel 3 fixed to the housing includes an RS-485 communication bus 38 of the printed circuit board 25, a backplane printed circuit board 6 bus and a first cable 8.

The second type of device with a separate panel 3 is designed for surface (mounted) mounting the device on the vertical elements of the cabinet. A separate panel 3 in this case can be fixed on the cabinet door, and the housing with functional modules is fixed on the mounting panel of the cabinet. A one-way service cabinet can be used to install this type of device.

In FIG. 10 schematically shows a separate panel 3 (left side of the figure). The second cable 32 is located between the second connector 23 and the connector 30 and is designed to power and communicate RS-485 panel 3. The second connector 23 is mounted on the printed circuit board 25 of the CPU module. The second Ethernet communication channel between the communication processor 33 and the PC connected to the panel 3 includes: a bus between the communication processor 33 and the Ethernet controller 34, a bus between the Ethernet controller 34 and the jumper block 35, a second Ethernet bus 37, a second cable 32, in addition to power and RS-485 communication for panel 3, Ethernet communication is also provided for a PC connected to panel 3, a bus of a printed circuit board of panel 3 and a communication cable with a PC.

The power to the panel 3 is supplied via the bus of the printed circuit board 25 of the CPU module and the bus of the backplane printed circuit board 6 from the power module.

The RS-485 communication channel between the communication processor 33 and the separate panel 3 includes an RS-485 communication bus 38 of the printed circuit board 25 of the CPU module and a second cable 32.

The jumper block 35 is designed to connect the first Ethernet bus 36 to the Ethernet controller 34 or to connect the second Ethernet bus 37 to the Ethernet controller 34. The choice of connection of the first or second Ethernet bus to the Ethernet controller 34 is determined by the type of device - with fixed to case panel 3 or with a separate panel 3. Block 35 jumpers are set to the desired position according to the order card, which indicates the type of device.

For surface mounting, a third type of device can be used - without a panel. To do this, the PCB 25 of the CPU module has an Ethernet connector 22 for connecting a PC cable, a third Ethernet bus 39 and a dual-port Ethernet controller 34. The device without a panel can be installed in a one-way service cabinet.

A variant is possible (not shown in the figure), in which for three Ethernet buses 36, 37 and 39 instead of a block of 35 jumpers and a two-port Ethernet controller, one three-port Ethernet controller is used.

Using panel 3 of the Ethernet interface for the PC, compared with the USB interface, allows you to use a significantly longer communication cable and connect several devices into a network. In addition, the Ethernet interface is widely used in industrial automation and has a galvanic isolation compared to the USB interface.

Having the ability to connect a panel with an Ethernet connector for a PC to the front and back sides of the chassis greatly simplifies the location and maintenance of the device in cabinets.

The device operates as follows.

Each board, each module and device assembly is pre-tested by the manufacturer. Then, a PC with IPO is connected to the Ethernet connector 31 on the panel 3 or Ethernet connector 22 of the CPU module and the digital signal processor and communication processor are configured to perform a specific technological task. After applying the supply voltage to the connector or connectors of the power module, the device enters the operating mode and starts the execution of the technological program.
