Description

  In the event of an accident in the power system, an accident that provides support for accidents by detecting supply problems and power generation problems, and providing support for accident recovery by displaying individual screens of electrical stations that require early recovery It relates to a recovery support system.

  Conventionally, accident recovery support systems adopted by electric power companies, etc. have an accident early warning support function, and when an accident occurs in the grid, data such as an accident summary is automatically entered in a prescribed format, and information is transmitted to related organizations. Was to be done. The information on supply failure and power generation failure displayed on the screen was updated in a timely manner from the time of the accident, so it was used as a guideline for completing the accident recovery process.

  On the other hand, with regard to the accident recovery support function, the accident was confirmed based on the operator's judgment of the accident aspect based on the accident recovery procedure determined in advance. Therefore, although the operator uses the accident recovery procedure, the operator needs to finalize the accident in the end.

  In addition, the operator determines the accident facility from the failure such as “shut-off CB”, “failure display and accident aspect” caused by the occurrence of the accident, and the operation status of the equipment. Judgment was made. Furthermore, in order to eliminate the supply hindrance, it was necessary to perform a recovery operation from the healthy system for each system.

  For this reason, technologies, etc. related to the power system accident recovery support system that calculates the optimal power generation adjustment amount according to the overload occurrence point of the power system and eliminates the overload by system switching, bus switching, load switching, etc. have been proposed. ing. (For example, see Patent Document 1).

In addition, there has been proposed a technique related to an accident recovery support system that creates an optimal recovery procedure in accordance with a system state after an accident, that is, an abnormal system state when a supply failure occurs in the power system. (For example, see Patent Document 2).

  In the conventional accident recovery support system, when the accident location is an upper station (220 kV, 110 kV) electric station, a wide-range power outage accident occurs. For complete recovery to the lower system (22 kV, 6 kV) customers, each electric station There is a problem that it takes time to switch between the control screens and a plurality of electric stations.

  FIG. 17 shows the transition of the previous screen display. From the grid macro screen, select the power station where the restoration operation is to be performed, and then select “Line A” from the “connected, 30F, relocation, distribution 2, 30F2” screen selection, and the power grid screen will be displayed. The When an operator recovers from an accident, it takes a lot of time to switch between a plurality of screens, which is a burden on the operator and a factor that takes a certain amount of time to recover.

  In addition, an automatic restoration device (ARE) is provided for each voltage class in each electric power station, but in the case of multiple accidents, it is subject to power failure depending on the equipment type (model) of the power failure equipment and the fault indication. The operator is also responsible for determining whether or not to perform the trial charging of the section, and it takes time to switch the fault display screen and to switch between multiple electric stations in order to check the all electrical station skeleton screen and the fault display screen individually. There was a problem of being.

  Furthermore, although an automatic recovery device (ARE) has been prepared to perform the recovery operation quickly, there is a problem that it takes time to perform recovery in units of electric power stations and voltage classes in accordance with predetermined priorities. there were. In addition, it was left up to the operator to make a restoration judgment for each system.

  For this reason, in an environment where wide-area power outages and lightning accidents occur frequently, there is a possibility of inducing human-related human errors and increasing the burden on the operator for restoration.

  The present invention has been made in view of such circumstances, and detects the occurrence of an accident in the power system, recognizes the power outage range, generates the restoration order until the completion of the accident restoration, and sets the power station according to the priority order. By displaying the recovery operation screen and assisting the operator in recovering accidents, it is possible to shorten the recovery time and improve the recovery level, reduce the burden on the operator, and prevent human-related human errors. The purpose is to provide an accident recovery support system.

  The accident recovery support system of the present invention is an accident recovery support system that supports recovery of an accident that has occurred in an electric power system, and is based on tidal current data at the time of the occurrence of an accident. A power failure determination means for determining whether or not a power failure has occurred and priority data for prescribing the priority of an electric station that performs accident recovery are prepared in advance, and the electric station where the accident has occurred and the occurrence of the power failure are determined to be “present”. In the subordinate electric power station, in accordance with the rank determination means for determining the rank of the electric station that performs the accident recovery based on the priority data, and the rank determined by the rank determination means, And a recovery operation screen display means for sequentially displaying the operation screen for performing the recovery.

  Here, the “electric station” means equipment such as a substation or a power station that supplies power in the power system.

  In addition, in the “priority data that defines the priority of electric power stations that perform accident recovery”, for example, it is necessary to recover accidents early, taking into account the social impact of customers in the areas where electric power supplies. Define the priority of an electrical station. That is, a high priority is set for an electric station that supplies power to a public facility, an educational institution, a medical institution or the like having a high degree of publicity. The rank determination means determines an electric station having the highest priority data as an electric station that performs accident recovery.

  In addition, it is possible to define the order of electric stations that are to be recovered from accidents at an early stage based on factors such as the order of electric stations from higher systems, the setting of supply trouble duration, and responsible discharge ensuring operation. .

  According to the present invention, it is possible to perform a series of processes from the detection of the occurrence of an accident in the power system to the operation for recovering the accident, so that the recovery time can be shortened in the end load system at the time of a wide-area power outage accident. Play.

  In addition, since the system determines the order of the electric power stations where accident recovery is performed, there is an effect of reducing the burden on the operator.

  In addition, the accident recovery support system of the present invention is provided with availability determination data for specifying whether or not to perform trial charging based on the type of equipment constituting the electrical station and the failure state of the equipment, and the electrical station where the accident has occurred In addition, the trial charging is performed to determine whether or not the trial charging can be performed based on the type of the equipment constituting the subordinate electric power station where the occurrence of the power failure is determined to be present, the failure state of the equipment, and the availability determination data. Based on the attribute of the availability determination means and the attribute of the customer who supplies power from each facility constituting the electric station, the priority data specifying the priority of the facility to perform the trial charging is provided, and the electric station on the restoration operation screen is In the display area of the facility to be configured, the determination result of whether or not to perform the trial charge and the order of the facility to perform the trial charge based on the priority data, the trial charge availability display means, and the electric station Constitution When a facility display area is selected by selecting a facility display area, the facility is equipped with a function to perform a trial charge on the facility via a transmission line, and in the determination of whether or not the trial charge can be performed. And a trial charging execution means for performing trial charging to the facility.

  Here, the “type of facilities constituting the electric station” means individual facilities such as “transformers” and “transmission lines” in substations, for example. "Failure state of the equipment" is a state such as "short circuit", "major failure", "oil spill", etc. that occurred in the equipment due to an accident, and these data are remote monitoring and control devices that perform monitoring control of electrical stations Etc. are transmitted.

  According to the present invention, the system determines whether or not the trial charging can be performed, so that it is possible to perform uniform, quick and accurate recovery without depending on the judgment power (capacity) of the operator, and to improve the recovery level. it can.

  In addition, as a result of the determination as to whether or not the trial charging can be performed, the implementation of the trial charging is restricted for the equipment that has been determined to be “No”, so that human error due to the human system can be prevented.

  In the accident recovery support system of the present invention, the rank determination means extracts customers to whom each electric power station supplies power, and performs accident recovery based on the attributes of the customers and the power usage status at the time of the accident. Data indicating the priority of the customer to be performed is generated, and the rank of the electric station where the accident recovery is performed is determined based on the data.

  Here, “customer attributes” are, for example, a numerical value of the social impact of the customer. For customers with a high degree of publicity such as public facilities, educational institutions, and medical institutions, a high value is set. Is done. The rank determination means determines the rank of the electric station that performs the recovery operation after adding up the numerical values of all the customers for the electric stations that supply power to a plurality of customers.

  In addition, in the calculation of the numerical value of the upper system electric power station that has the electric power station in the lower level, by setting to add the numerical value of the lower electric power station in addition to the value of the local power station, all electric power stations were determined uniformly. Even in such a case, it is possible to ensure that priority is given to the upper-level electric station.

  The customer's “power usage status at the time of the accident” is the data of the customer's power usage at the time of the accident transmitted from the remote monitoring control device, etc. The customer's operating status at the time of the accident is determined from the actual power consumption data. As a result of the determination, the numerical value of the customer who is determined not to be in operation at the time of the accident is excluded from the addition target, and the electric station where the restoration operation is performed is determined.

  In addition, in the determination of the electric station where the restoration operation is performed by the rank determination means, other power supply methods such as supply from other power supply companies with different supply routes by the customer, private power generation facilities and power storage facilities, etc. By providing the data on whether or not to prepare in advance, the rank determination means refers to the data, excludes the numerical value of the customer having other power supply methods from the addition target, and determines the electric station that performs the recovery operation Can also be done. Thereby, the effectiveness of the selection of an electric station in consideration of the social influence degree can be enhanced.

  Furthermore, the operator can also select the restoration operation at the next-ranked electric station without considering the restoration operation of the output electric station in consideration of other factors. It is also possible to set so as to display a restoration operation screen of an electric station that is highly selectable by an operator by reducing the numerical value of the electric station that has not been selected. Thereby, the efficiency of an operator's operation can be improved.

  The rank determining means compares and determines numerical values for each electric station, and the restoration operation screen display means outputs the restoration operation screens for electric stations in descending order of the numerical values. After the restoration operation screen is displayed, there are some electric stations that cannot be restored depending on the result of the operator's restoration operation. Separate the location and determine the electrical location that prioritizes the recovery operation.

  According to the present invention, it is possible to shorten the recovery time in the end load system in a wide-area power outage accident.

  In addition, when the operator recovers the power system accident, the recovery operation screen of the electric power station corresponding to the priority order of recovery is displayed in a transitional manner, so that it can be unified and quickly performed regardless of the judgment (capacity) of the operator. It is possible to perform proper recovery and prevent human error of the operator.

  Furthermore, the accident warning function in the conventional accident recovery support system has been limited to simple information support to the operator. However, according to the present invention, it is possible to shift to the actual accident recovery operation, so the level of recovery is improved. And the burden on the operator can be reduced.

  In addition, since the system supports the determination of whether or not the trial charging can be performed in the section subject to the power failure, it is possible to prevent erroneous operation and prevent damage to the equipment, and further prevent further accidents.

Hereinafter, a first embodiment of the accident recovery support system 1 according to the present invention will be described.
FIG. 1 is a diagram showing a system configuration of an accident recovery support system 1 according to the first embodiment. The accident recovery support system 1 of the present embodiment is generated in the system in cooperation with the main computer (MP) of the monitoring control system 3 that is connected to the control LAN of the power system and the power supply information LAN and performs monitoring control of the system. Supports accident recovery and displays information related to accident recovery on each operator's desk.

FIG. 2 is a functional block diagram of the accident recovery support system 1 of the present embodiment.
The accident recovery support system 1 of the present embodiment is connected to a monitoring control system 3 and a TC (remote monitoring control device) (master station) 4 via a network 2 such as a LAN. The TC (master station) 4 is connected to a TC (slave station) 51 installed in the substation A · 5 and a TC (slave station) 61 installed in the substation C · 6 via a communication line.

  The substation A · 5 located above the transmission line 9 constituting the power system includes a power receiving CB 52, a transformer 53, and a power transmitting CB 54, transforms the received power and transmits it to the lower system. Substation C.6 located under substation A.5 has CB62 for power reception, transformer 63, and CB64 for power transmission, transforms the received power and transmits it to the subordinate system, customer X, customer It is assumed that power distribution to Y is performed, and CB 65 and 66 are installed in each distribution line.

  The accident recovery support system 1 includes a transmission / reception unit 11 connected to the network 2, a central processing unit 12 that performs arithmetic processing related to accident recovery support in the power system, a storage unit 13 that holds information necessary for accident recovery support, and data. An input unit 14 such as a keyboard for inputting data and a display device 15 for outputting data or an output unit 15 such as a printer are constituted.

  The central processing unit 12 includes a transmission / reception processing unit 121 that exchanges data with the transmission / reception unit 11, an input / output processing unit 122 that exchanges data with the input unit 14 or the output unit 15, and a substation A in the upper system. -Power failure determination means 123 that determines whether or not a power failure accident has occurred in substations C.6, etc. in response to an accident such as 5; , Restoration operation screen display means 125 for displaying the restoration operation screen of the electric power station where the power failure occurred, transformers 53 and 63 provided in the substations A, 5, C, 6 where the power failure occurred, the transmission line 9, etc. Trial charge availability judgment means 126 for judging whether or not the trial charge can be carried out for the equipment of this type, trial charge availability judgment means 127 for displaying the result of the trial charge availability judgment on the recovery operation screen, and “possible” for the trial charge implementation. Judged Facilities to comprise a 試充 electrostatic execution means 128 for implementing the 試充 electricity.

  The storage unit 13 includes a system DB 131 that stores screen data such as a system macro diagram and an electric station skeleton diagram displayed on the monitoring control screen, an equipment DB 132 that stores data related to equipment constituting the power system, and an accident that has occurred in the power system Of the accident DB 133 that holds the data of the power station, the screen transition table 134 that displays the recovery operation screen of the electric station that gives priority to the recovery operation from the electric power station where the power failure occurred, and the equipment included in the electric station where the power failure occurred On the other hand, it is comprised by the trial charge determination table 135 used for determination of the feasibility of trial charge implementation.

  In FIG. 3, the structural example of equipment DB132 is shown. In the facility DB 132 of this example, the name and type data of the facilities owned for each electric station are held, and position information necessary for displaying various system screens is held.

  In FIG. 4, the structural example of accident DB133 is shown. In the accident DB 133 of this example, data such as the date and time of the occurrence of the accident, the name of the electric station where the accident occurred, the equipment causing the accident, and the name and type of the equipment where the accident occurred are spread. In addition, it retains data of subordinate power stations and facilities that have been affected by the power system accidents and caused power outages.

  Here, the subordinate electric station where the power outage accident has occurred due to the accident at the upper electric substation is determined with reference to the data of the power flow at the time of the accident held by the supervisory control system 3 (power outage determining means 123). ).

  A specific example is shown in FIG. First, when an accident cause facility is specified by the function of the monitoring control system 3, the power failure determination means 123 causes a power failure accident to occur in an electric station in the direction of the current from the accident cause facility based on the current flow at the time of the accident. Identify the electrical station where it occurred. The power failure determination means 123 inputs the name of the identified electric station in the “electric station name” field of the accident DB 133.

  FIG. 6 shows a configuration example of the screen transition table 134. In the screen transition table 134 of this example, a wide range of power outage accidents caused by an accident at a higher-level electric station is generated as a unit, and data defining the priority of the electric station to be restored is held.

  Specifically, in this example, “accident occurrence time = XXX: XX accident cause equipment = substation A, transformer: XXXXX”, substation A and substation C where the power failure occurred. Judgment of restoration priority. It should be noted that the data of the electric power station where the power failure occurred is extracted from the accident DB 133 (FIG. 4) and inputted (rank determination means 124).

  In this example, the data (priority table) that defines the priority of the power plant and equipment to be restored is determined and held in advance by the administrator in consideration of social influences. The rank determination means 124 generates a restoration priority based on the priority table and inputs the restoration priority to the screen transition table 134 when there are a plurality of electrical stations to be restored.

  In addition, the priority order determination element may be set based on the order of the electric power station from the higher system, the setting of the supply trouble duration, the responsible discharge securing operation, and the like.

  Furthermore, in the screen transition table 134 of this example, data on “failure display” and “determination element” of equipment necessary for determining whether or not trial charging can be performed is held, and the trial charging or not determining unit 126 determines from these data. It is determined whether or not trial charging can be performed.

  Here, the determination as to whether or not the trial charging can be performed by the trial charging execution determination unit 126 is performed based on the trial charging determination table 135. FIG. 7 shows a configuration example of the trial charge determination table 135. This example is a determination criterion when the target device is a “transformer”, and different determination criteria are used in the case of different types of equipment such as buses and power transmission lines.

  FIG. 8 is a diagram showing an outline of a processing flow in the accident recovery support system 1 of the present embodiment.

  When an accident such as a lightning strike occurs in the power system (S101), the facility of the accident is specified by the function of the supervisory control system 3, and the presence or absence of an electric power supply trouble that may occur with the accident is determined (S102). .

  If a supply failure has occurred (“occurring” in S102), the tidal current before the accident is calculated for each electric station and aggregated by system (S103). As a result, it is possible to identify the subordinate electric station where the power outage accident has spread due to the supply trouble occurring in the upper electric station (power outage determining means 123).

  After the identification of the electric station where the supply failure has occurred in S103, the function of the monitoring control system 3 is used to determine the presence or absence of a device in which a power failure has occurred due to the operation of a protective relay (not shown) (S104). It should be noted that even when no supply hindrance has occurred ("No occurrence" in S102), the occurrence of a power failure in the equipment at the electric station where the accident has occurred is confirmed.

  When there is a device in which a power failure has occurred ("Yes" in S104), the trial charging execution availability determination unit 126 determines whether the trial charging can be performed for the corresponding device (S105).

  After determining whether or not the trial charging can be performed in S105, the order determining unit 124 generates data defining the order of the electric stations to be restored based on the set initial value (S106). Note that if there is no device in which a power failure has occurred ("None" in S104), data indicating that there is no device to be restored is generated (S106).

  After the data defining the restoration order is generated, the control / monitoring screen of the electric station that performs the restoration according to the order of the data is displayed at any time (recovery operation screen display means 125). If there are unrecoverable facilities, the non-recoverable facilities are excluded and the power flow is calculated again, and an electric station control / monitoring screen giving priority to recovery is displayed as needed (S107).

  In addition, in the display of the control / monitoring screen of the electric station, the restoration operation screen of the electric station where a power failure has occurred in the facility is quickly displayed (S107).

  As a result, the pre-accident tidal current and the equipment failure status at the time of the accident are taken in, and it is quickly determined whether or not it can be restored. It can be performed.

[Flow when supply trouble or power generation trouble occurs]
FIG. 9 shows a detailed flow when a supply trouble or the like occurs in the power system.
Here, “supply hindrance” refers to the case where the supply of electricity to the user of electricity is stopped due to an accident of damage to the electric work or the use of electricity is urgently restricted. "Active power * duration" before the outage of the power outage facility. “Power generation trouble” is a generator stop (parallel CB trip), and “power generation trouble amount” means “generated power * duration” before the power station is stopped.

  First, when an accident occurs in the power system (S201), supply troubles and power generation troubles are detected by the remote monitoring and control devices 51 and 61 provided in the electrical facilities of the accident cause equipment (S202). Thereafter, when trouble continues during the failure confirmation time (“YES” in S203), guidance to the operator by voice or the like is given. Specifically, the message “Supply trouble / Power generation trouble” will be displayed on the system macro screen together with the voice “Power supply trouble / power generation trouble due to system fault occurrence” to alert the operator. (S204).

  On the other hand, when the trouble does not continue during the failure confirmation time (“NO” in S203), the process is terminated (S205).

  FIG. 10 shows a normal display example of the “system macro screen” in the accident recovery support system 1 of the present embodiment. On the system macro screen on which all the electric stations in the jurisdiction are displayed, display areas of “supply failure” and “power generation failure” are installed.

  FIG. 11 shows a display example of the “system macro screen” after the system accident occurs. In this example, the recovery situation in the B trunk line FT accident is shown.

  In the event of a wide-range power outage accident, etc., the main system and main substations are immediately restored by the operator. However, according to the accident recovery support system 1 of this embodiment, the restoration of all terminal systems is quickly and accurately performed. It can be carried out.

  In addition, by displaying a mark such as “lightning” indicating that the accident has been confirmed on the main accident-causing equipment (FIG. 11), the initial operation of the operator is supported.

  In a specific operation, the operator selects the display area of “supply failure” and “power generation failure” displayed on the recovery operation screen (FIG. 9, S206), and the skeleton screen of the current supply failure electric station is displayed. (S207) It is possible to switch to control and shift to a recovery operation (S208). In addition, when shifting to the next electric power station, supply troubles and power generation troubles can be resolved quickly and reliably by repeating the above operation.

  If the trouble continues after completion of the recovery operation (“YES” in S209), the color change display of “supply trouble” and “power trouble” on the system macro screen continues (S210), and S206 to S208. Repeat the process.

  On the other hand, if the trouble does not continue after the completion of the recovery operation (“NO” in S209), the color change display of “supply trouble” and “power trouble” on the system macro screen is turned off simultaneously with the end of the processing. (S211).

  Note that in the accident recovery support system 1 of the present embodiment, trial charging is performed on the facility where a power failure has occurred in the recovery operation of S208. Specifically, it is shown below.

  First, the trial charge execution availability determination unit 126 extracts data on the failure state of each facility at the time of occurrence of the accident obtained by the remote monitoring control devices 51 and 61. The extracted failure status data includes “failure indications” such as major faults and short circuits, and “determination factors” such as total cooler shutdown, oil spill, and overload temperature. The means 126 inputs such data in the “failure display” and “determination element” fields of the screen transition table 134 (FIG. 6).

  Next, the trial charge availability determination unit 126 performs the screen transition table 134 and the trial charge determination table 135 (FIG. 7) when the electric power station recovery operation screen is sequentially displayed (the recovery operation screen display unit 125). Reference is made, and whether or not the trial charging can be performed is determined for each unit constituting the electric station.

  Specifically, when the “failure display” and “determination element” input to the screen transition table 134 are not the “failure display” and “determination element” defined in the trial charge determination table 135, the on-site confirmation is performed. It is determined that the trial charge can be performed without waiting, and the trial charge execution availability display means 127 displays the symbol of the corresponding facility on the skeleton screen as the recovery operation screen so that the trial charge can be performed.

  The remote monitoring control devices 51 and 61 also check the open / closed state of the CBs 52 and 53 etc. for performing the trial charging of the equipment, and input them in the “trial charging CB” column of the screen transition table 134 (FIG. 6). The trial charge execution possibility determination unit 126 also refers to the data of “trial charge CB” of the facility to be determined, and does not perform trial charge when it is “OFF”.

  Even if it is determined that trial charging can be performed without waiting for on-site confirmation in the data on the failure state of the equipment at the time of the accident, if it is recognized that there is a serious problem with the trial charging Therefore, the trial charge on the recovery operation screen is not carried out at the operator's discretion, but after the local confirmation.

  The trial charging execution unit 128 receives the selection of the equipment symbol by the operator and carries out trial charging for the relevant equipment by the remote monitoring control devices 51 and 61 connected via the network 2. Specifically, for example, when the trial charging is performed on the transformer 53 of the substation A · 5, the power reception CB 52 is opened by the TC (slave station) 51 and the system voltage is supplied.

  On the other hand, in the screen transition table 134, the occurrence of a combined display accident of “short circuit” and “serious failure” is indicated in the “failure display” and “determination element” of the equipment, and when the power receiving CB 52 is off, the trial charging is performed. Display prohibited display on the recovery operation screen. In addition, when it is determined that the power failure generating device cannot be restored by the failure display classification, it is preferable to immediately recognize the operator and set the initial response such as local response.

  In FIG. 12, the example of a display of the recovery operation screen in the accident recovery assistance system 1 of this embodiment is shown. Both the primary side CB and the secondary side CB of the transformer are displayed in large colors by changing colors to stand out, thereby alerting the operator.

  In addition, even if the operator erroneously selects a CB symbol for which the trial charging is prohibited in order to perform the trial charging of the CB, the system monitoring function performs the selection canceling process and the violation message. Further, the alarm is triggered by a system buzzer or the like, thereby avoiding continuation of the operation (trial charge execution means 128).

  FIG. 13 shows a display example of a conventional recovery operation screen. Previously, the details of the failure state of the equipment were displayed on the screen, but there was no possibility that the data was mutually linked, and there was a risk of erroneous operation due to human error of the operator. The problem is solved on the screen (FIG. 12).

[Second Embodiment]
Next, a second embodiment according to the accident recovery system 1 of the present invention will be described.
This embodiment is different from the first embodiment in that the storage unit 13 includes a customer DB.

  In FIG. 14, the structural example of customer DB in this embodiment is shown. In the customer DB of this example, data of a customer who supplies power is held. Specifically, information on the name of the customer, the electric power station that supplies power to the customer, and the transmission line / distribution line is held.

  In addition, based on the public nature of the customer, etc., whether there is a point indicating the priority of recovery from a power outage accident or whether there is another power supply method in addition to the power supply method in which the customer was out of power in the event of a power outage accident Such information is held.

  These points are set according to the attributes of the equipment such as “elementary school” and “city hall”. In addition, points can be changed according to the scale of the equipment. Furthermore, the effectiveness can be further enhanced by adjusting the points according to the time, day of the week, weather conditions, and the like.

  In addition, the screen transition table 134 according to the present embodiment holds information on customers who supply power from facilities such as power transmission lines and distribution lines, in addition to information on the names of electric stations and the names and types of facilities in the stations. (FIG. 15). These pieces of information are extracted and input from the customer DB (FIG. 14) based on the equipment name data (rank determination means 124). The customer information includes “early recovery point” data, and the order determination means 124 determines the priority of recovery based on these data.

  FIG. 16 shows a flow for determining an electric station and equipment for which restoration is prioritized in the second embodiment.

  First, upon selection of “supply failure” and “power generation failure” that are highlighted on the system macro screen in response to the occurrence of an accident in the power system (S301), the power failure determination means 123 identifies the power station where the power failure occurred. (S302).

  Next, with respect to the plurality of identified electric stations, the screen transition table 134 (FIG. 15) is referred to, and the recovery operation screens are displayed in descending order of the total of the early recovery points (S303) (S304 / rank determination means 124). ). As a result, it is possible to quickly and objectively select an electrical station that requires the most rapid recovery, thereby realizing efficient accident recovery.

  In the accident recovery support system 1 of the present embodiment, when the target electric station is located at the upper position and the electric station is located at the lower position in the sum of the early recovery points, the lower electric station supplies power. The customer's points to be added are also added to the points of the upper electric station. Furthermore, by setting a unique point in the lower electrical station itself, it is possible to make sure that it is selected from the upper electrical station.

  In the example of FIG. 15, the point of “substation A” is “265 points”, whereas “substation C” is “170 points” and “substation F” is “105 points”. The restoration operation screen of “Substation A” with the highest point is displayed with priority.

  After the restoration operation screen is displayed, it is determined whether or not the trial charging can be performed for the power failure equipment constituting the electric power station (S305 / trial charging availability determination unit 126), and the trial charging availability display unit 127 performs the trial charging. As for the power outage facility in which “Yes” is set to “Yes”, an early recovery point comparison judgment is performed (S306).

  In the example of FIG. 15, the transmission line “XXXX” at substation C supplies power to 45 points “XX factory” and 60 points “XX bank”, whereas “XXXXX” supplies power to 65 points “XXX Elementary School”. The trial charge execution availability display means 127 compares 105 points, which is the total of the supply destinations of the transmission line “× XXX”, with 65 points, which is the supply destination of the transmission line “× XX”, and gives more points. Select to carry out a trial charge on the high-power transmission line “XXXX”.

  Next, the trial charge execution possibility display means 127 displays the symbol of the facility that prioritizes restoration on the skeleton screen, which is the restoration operation screen, after the selection of the facility that prioritizes the restoration operation, thereby causing the operator to perform the restoration operation. Guidance is performed (S307).

  The operator selects the blinking symbol and performs the trial charging to the corresponding equipment unless the trial charging is recognized as having a serious trouble (S308 / trial charging execution means 128). As a result, the accident can be recovered in an optimal order in consideration of social impact.

  In addition, when the power station subject to the recovery operation is a substation, the “type” of equipment must be determined before the “early recovery point” is determined. By setting the priority of “high”, it is possible to select the trial charging of “transformer” first.

  Moreover, in the accident recovery assistance system 1 of this embodiment, the point used for determination of the electric station which performs recovery operation can be adjusted based on the electric power usage condition at the time of a customer's accident occurrence.

  Specifically, the rank determination means 124 first acquires the customer's power usage data at the time of the accident transmitted from the remote monitoring control devices 51, 61, etc., and prepares the customer's power usage at the time of operation in advance. Compare with actual results data. The rank judging means 124 operates when an accident occurs when the “data of customer's power consumption at the time of the accident” is less than a predetermined ratio (for example, 50%) of “actual power consumption data at the time of operation”. Judge that it is not the situation. For customers who are not in operation at the time of the accident, there is no need to perform a recovery operation at an early stage. Therefore, the customer's numerical value is excluded from the addition target, and the electric station where the recovery operation is performed is determined. As a result, it is possible to efficiently recover the accident according to the state of power supply when the accident occurs.

  Moreover, in this embodiment, in selection of the facility giving priority to the restoration operation, it is possible to make a determination with reference to data of “another power supply method” provided in advance in the customer DB (FIG. 14). Here, “another power supply method” means a supply from another power supply company with a different supply route, a private power generation facility, a power storage facility, or the like provided independently.

  As a specific determination procedure, the customer DB (FIG. 14) is referred to when determining an electric station that performs a restoration operation by the rank determination unit 124 or a facility that performs trial charging, and “other power supply method” is set to “ Equipment with “Yes” is excluded from the calculation of “Early Recovery Points” above. As a result, it is possible to preferentially perform the recovery operation for the electric station or equipment that should truly give priority to recovery.

  Furthermore, the accident recovery support system 1 of the present embodiment can reflect the operation history of the operator when calculating the “early recovery point”.

  For example, even if the restoration operation screen for the electric station determined to give priority to restoration is displayed by the rank determination means 124, the operator selects the restoration operation at the next electric station in consideration of other factors. It is also possible to do. In such a case, it is determined that the electric station of the previous rank where the recovery operation by the operator has not been performed is an electric station that the operator does not actively select, and the “early recovery point” of the screen transition table 134 is set to a predetermined value. Enter a minus point. The rank determination unit 124 selects an electric station that performs the recovery operation with priority based on the “early recovery point” from which such points are reduced.

  Similarly, when selecting a facility for performing a trial charge, if a facility not based on the guidance by the trial charge execution availability display means 127 is selected, the screen transition table 134 is set to a facility that has not been selected based on the guidance. The predetermined points will be reduced to “Early Recovery Points”.

  As a result, it is possible to reflect the operation history of the operator in the guidance of the image display or trial charge execution of the electric station, so it becomes possible to appropriately guide the electric station or equipment that is highly likely to be selected by the operator, Furthermore, accident recovery operations can be performed quickly and efficiently.

  As described above, according to the accident recovery support system 1 of the present invention, it is possible to provide guidance for recovery operations applying various criteria according to the situation, so that quick and accurate recovery can be performed.
