Description

  The present invention relates to a technique for supporting a response including maintenance and repair to a power supply facility used when supplying power.

  Currently, it is usual to manage a plurality of facilities together. For example, production equipment in a factory is maintained by maintenance personnel. In addition, maintenance staff manage the steel towers and distribution facilities in the transmission line over a wide area.

  When managing such a plurality of facilities collectively, a failure such as a failure may occur in parallel in the plurality of facilities. In other words, it may be necessary to deal with a plurality of facilities at the same time. In such a case, since the personnel is limited, it is difficult to cope with both (or more) facilities in parallel. For this reason, there is a need for a technique for deciding which facility to prioritize.

  Patent document 1 is proposed as a response to this. Patent Document 1 aims to determine the priority of correspondence in accordance with the status of each facility in which an abnormality has occurred when several abnormalities occur simultaneously in several facilities. In Patent Document 1, the priority order is determined based on operation information, master information regarding the production process in each production facility, and importance evaluation items of the production facility. Further, in Patent Document 1, it is also possible to determine the priority order reflecting the current situation by collecting operation information of each production facility and updating the database.

JP 2006-39650 A

  Here, the power supply facility is connected to the other power supply facility with an electric wire, and in such a case, it is necessary to consider connection with the other power supply facility. However, in Patent Document 1, only the operation status of a target production facility is considered. For this reason, the influence which the failure which generate | occur | produced with one installation has on another installation is not considered. For this reason, it is not possible to determine the priority in consideration of the influence on the entire system constituted by each facility. In other words, it was not possible to identify priorities that corresponded to the actual situation regarding the measures in facilities that affect each other.

  Therefore, in the present invention, the priority of correspondence is determined using the connection relationship between facilities as a unit and using the priority calculated in accordance with the preset importance and the connection status. More specifically, when it is necessary to deal with a plurality of facilities at the same time, the importance levels of the facilities are compared, and if they match, the operating status and / or connection of the system (with other facilities) The relationship (how many facilities and connections are maintained) is detected, and the priority is specified (calculated) based on this. In particular, the importance of the connection relationship having a redundant configuration with respect to the system is set to the highest level, each system is detected as being inoperable or a part thereof is detected as being inoperable, and the priority of each system being inoperable is set to be the highest. Also, in such a case, for connected systems, check whether or not it is possible to supply power from other equipment except for equipment that is detected as being inoperable. , Raise the priority of the facility that makes it impossible (for example, completely) to supply power to the connected system, or make it the highest priority. In addition, when there are a plurality of grid interconnection facilities that correspond to these conditions, the number of facilities in the partner (connection destination) area to which each grid interconnection facility is linked (this is the grid interconnection) It means the number of affected facilities due to the occurrence of abnormalities in both systems), or by comparing the elapsed time since the abnormality occurred and the power supply to the connected area was stopped, Update maintenance / inspection priority of interconnected equipment (equipment of importance A).

The following aspects are also included in the present invention.
In a support support method for a power supply facility, which is connected to each other by an electric wire and determines the order of response to the failure of the power supply facility for conducting electricity through the wire,
For each of the plurality of power supply facilities, a detection device that detects the operation status of the power supply facility is installed,
A management server connected to each of the detection devices,
For each of the plurality of power supply facilities, the importance of each connection relationship of other power supply facilities connected via the electric wires is stored in a storage device,
Shows the operating status of the corresponding power supply facility from each of the detection devices at regular intervals, and receives a signal indicating the operating status for each connection relationship between the power supply facility and another power supply facility connected by the wire. And
The received signal detects whether there is a failure in any of the connection relationships,
When the failure is detected, it is determined based on the signal whether there are a plurality of detected failures,
When it is determined that there are a plurality of failures, the importance of the connection relationship that is the detected failure location is specified from the stored contents of the storage device,
If the priority matches when the identified importance is compared, the priority specified from the connection status between the power supply facility and another power supply facility based on the signal is compared,
The correspondence order is calculated according to the priority.

In addition, in this support method for power supply equipment,
The importance is set to the highest level when there are a plurality of systems including wires with other power supply facilities in the connection relationship,
The management server also specifies the priority of the connection relationship having the highest importance among the priorities based on the number of abnormalities based on the failure among the plurality of systems. include.

  In addition, in the importance of the power supply equipment set based on this response support method, the power supply equipment used for the connection portion with the system including other power supply equipment and electric wires is set at the top. In the case where the system including other power supply facilities and electric wires has only one grid connection portion that functions effectively, it is connected with other power distribution facilities including multiple grid connection portions and other systems including wires. Compared with the equipment used for the grid connection part installed in the system having a plurality of system parts, the priority may be set higher, and the abnormality may be recovered quickly. Here, the case where there is only one linkage part means that a plurality of linkage facilities are not installed from an economic point of view, but based on the idea of performing interpolation in the installation of a backup power source or the like, or redundant on the system However, there are cases where the spare grid connection portion cannot be used due to work blackouts or accidents.

  According to the present invention, even when other facilities are affected, the correspondence order can be specified.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows an example of the configuration of an electric power system to be controlled by this embodiment (an example of an equipment installation situation in a power transmission / distribution system). In this example, the target power system is composed of four or five (case 8) areas, and the transmission and distribution networks laid in each area are linked lines (link lines are linked to each transmission and distribution network). Redundant configuration by duplication).

  As shown in this figure, the power transmission / distribution system laid down by this system is used at power plants for the purpose of supplying power to contract customers (housing, factories, etc.) scattered in a certain area. It is assumed that the power generated or stored in the power storage device is supplied via power supply equipment (transmission line, distribution line, transformer, pole transformer, etc.). For each base, the equipment name (identification information) of each equipment located at the base and the installation coordinates indicating the installation position are managed as data.

  FIG. 2 is a block diagram of the embodiment of the support support method (maintenance / inspection priority order) determination (update) system for the power supply facility according to the present embodiment. In this maintenance / inspection priority determination (updating) system, as shown in FIG. 1, the state of the power supply facilities E101, E102,... When an abnormality occurs, the status of each power supply facility at the measurement level given by each facility or each facility + environment in advance, and the measurement signal of each power supply facility obtained as a result of performing the measurement sequentially Necessary according to the status of each facility obtained by comparing the measured value threshold value with the measured value threshold value measured for each facility / equipment, etc. Various data required to determine whether or not it is possible to compare the technical level and the qualifications possessed by the workers who actually perform maintenance and inspection work on each facility and equipment Source (power transmission / distribution facility monitoring status DB 121, maintenance / inspection work plan DB 122, and technology level DB 127 required for responding to the state (level) of each facility / equipment), and for each collected facility / equipment Various information regarding the facilities to be updated on the power transmission / distribution facility monitoring status DB 121 for determining the priority of maintenance / inspection work to be performed for each facility / equipment according to the status of the system and the connection status of the system, In order to determine the normal / abnormal state for each measurement value type, the measurement value level and abnormality detection for each equipment type that determines the measurement value level and abnormality detection level based on the design information and operation results of each facility / equipment. It is sequentially updated according to the abnormality level of each facility / equipment determined by comparing the measurement information of each facility / equipment with the setting of DB “DB123” for setting the level. , Information indicating the maintenance / inspection route for each maintenance / inspection group, the management server 100 installed in the facility serving as the base for each area, and a portable terminal (cell phone / notebook) carried by each maintenance / inspector PC / tablet PC / other portable information terminals etc.) 200 and car navigation devices installed in maintenance / inspection vehicles owned by each maintenance / inspection group, or a predetermined update cycle or power transmission・ Distribution when the occurrence of any abnormality in the maintenance / inspection facilities / equipment on the distribution facility monitoring status DB 121 is confirmed, and maintenance / inspection of the area where the abnormality occurred is installed. It is possible to cope with the technical / skill level of the members (workers) that make up the group in charge of the work, or abnormalities that are difficult to deal with If the result shows that the group in charge of maintenance / inspection in other areas needs to take action, the group in charge of maintenance / inspection in other areas Search for a group with the corresponding technology / skill, extract possible candidates so that the corresponding maintenance / inspection group can respond, and notify the maintenance / inspection group of the route It is.

  Here, the monitoring contents of the power transmission / distribution facilities of the electric power company described in the grid operation rules will be described. In the electric power company, monitoring items include distribution equipment operation status, system status such as voltage and grid current, sending voltage, current, feeder current, switching information of circuit breaker and line switch, sending voltage / current, protection Monitor device operation information. As the monitoring method, communication from the system monitoring device or related points, remote display device for power distribution (distribution SV: abbreviation of Supervision) and related points, and communication from the monitoring control device and related points are performed. In addition, the transmission voltage is controlled automatically by grasping the load curves of the distribution lines and substation voltage devices and performing appropriate control, and managing and analyzing the system status to maintain and improve supply reliability. Communication from equipment, monitoring and control equipment, distribution line automatic control system, and related parts. As for the monitoring status of the distribution line, the voltage and current of the distribution line are measured by the substation TC, sensor switch, etc. (there is an electric power company under test operation) at the delivery end of the distribution line or in the middle of the line. At the same time, automatic voltage adjustment has been performed by an on-load tap switching transformer (LRT), which is one of the voltage regulators in the system. Here, when using the LRT, a dead zone is provided in consideration of the life of the LRT tap changer (approximately 200,000 times or more). In addition, the application range regarding LRT is defined for each electric power company. The content is that tap switching is performed when a value exceeding the range set as the dead zone is measured based on each operation time period.

  At present, there are general types, bidirectional types (fixed for reverse feed taps), and distributed power supply compatible types of SVR (voltage regulator), and each SVR is applied to each power company. Yes. The SVR is the most common device for adjusting the voltage of the high-voltage distribution line, and is used by each electric power company as a countermeasure against the supply voltage. At this time, the general and bidirectional SVR set values are defined in each power association. When the measured value exceeds the range set as the dead zone based on the determined operation time period, tap switching is performed.

  Each electric power company sets a distributed power supply compatible SVR set value. When the measured value exceeds the range set as the dead zone based on the set operation time limit, tap switching is performed. In addition, in each electric power company, the installation status of the self-excited SVC, the setting contents, and the like are also set. Furthermore, in each electric power company, the installation status of the separately excited SVC (TCR), the setting contents, and the like are also set.

  In addition, the equipment capacity of power capacitors installed on the distribution lines (intermediate and terminal) of each power company is also managed. Management is done for each difference between automatic and manual opening and closing. Some electric power companies have introduced SC (Shunt Capacitor) and ShR (Shunt Reactor).

  Furthermore, FIG. 3 shows a list of devices / systems (as described above) for the purpose of voltage adjustment to which the present invention is applicable.

  Next, the concept of the measurement value level will be described with reference to FIG. For each facility / equipment installed in the power distribution system described above, each facility / equipment type and each facility / equipment is installed for the measurement values obtained as a result of measuring the measurement items of each facility / equipment. Depending on the environment, the meaning of the measurement results will vary. Therefore, in this method, it is explained that the range of the measurement value level is set according to the concept shown in this figure for each facility / equipment type and installation environment. That is, since a certain level (level 3 in this example) is exceeded immediately after the predictive period, monitoring here is necessary. The purpose of this embodiment is to solve this problem.

  Next, the contents of a DB (power transmission / distribution equipment monitoring status DB) 121 for holding the monitoring status of the power supply equipment to be monitored in the present embodiment are shown in FIGS.

  On this DB, the area where each equipment is installed, the equipment installation position, the importance of the equipment, the equipment measurement information, the level of the measurement information (measurement value level), and the number of times the measurement information is determined to be abnormal ( Abnormal level measurement count), the time when the level indicating abnormality is continued in the measurement information (measurement signal abnormal level duration), equipment operation status, equipment configuration (redundant configuration / single configuration), and response to redundant configuration Equipment to be used (This item is set when the equipment importance level is A), connected equipment (holds information related to equipment connected to each equipment (this information varies depending on the system status), priority for each area equipment importance level (T) is held.

  Next, FIG. 6 shows the contents of the maintenance / inspection group configuration and work qualification (work location (start point) / current location / area in charge, qualification, current situation) DB 130. This DB 130 is the workers who make up each maintenance / inspection group, the work place of each worker, the current location of each maintenance / inspection group, the area in charge, the qualifications held by each maintenance / inspection worker, and each maintenance / inspection Holds the current state of the group (working / moving).

  Next, FIG. 7 shows the contents of the measurement value level and abnormality detection level setting DB 123 for each equipment type. Here, the figure which sets the measured value level for every equipment classification and measurement information, and the measured value level which detects abnormality is shown. Since the range of measurement values that should be recognized as abnormal differs for each measurement information, an abnormality detection level is set for each measurement information as shown in this figure.

  Next, FIG. 8 shows the equipment state (level) DB 124 before starting work. This is a DB for holding the equipment state before starting work. This DB holds the equipment state before starting work for each area target equipment.

  Next, FIG. 9 shows a maintenance / inspection work plan DB 122 (prepared for each execution date) 122. This is a maintenance / inspection work plan DB created in advance before work. This DB is created in advance by each maintenance / inspection group before starting work.

  Next, FIG. 10 shows the working equipment state (level) DB 126. Based on the data collected from each facility, the state (level) information of each facility obtained as a result of performing the determination is stored in this DB.

  Next, FIG. 11 shows a table showing the maintenance / inspection work plan DB (updated based on the facility information measured every implementation date). Here, the result of updating based on the state information of the equipment measured during work for each execution date is stored. This corresponds to the maintenance / inspection work schedule DB 125.

  Next, FIG. 12 shows a technical level DB 127 necessary for handling according to the level of each equipment type. This is a DB for setting a technical level necessary for implementing a response corresponding to each level set for each equipment type. In this DB, qualifications necessary for maintenance / inspection when each level of event is detected for each equipment type is defined. Therefore, maintenance / inspection groups with workers with the qualifications mentioned above are repaired.・ It can be assigned to inspection work.

  Next, FIG. 13 shows the equipment type DB 128 of each monitoring target equipment. This is for registering information related to the equipment type of the monitoring target equipment laid in each area.

  Hereinafter, the contents of processing in the embodiment of the present invention using the above-described DB will be described with reference to the drawings. Each process (step) is executed by the management server 100 unless otherwise specified.

First, an overall flow executed by the management server 100 is shown in FIG.
In Step1, the setting that is a precondition for executing this flow is executed. The equipment targeted in this embodiment is power transmission / distribution equipment, and is a group of equipment having a wide area, so the maintenance / inspection range is very wide. Therefore, the entire target area is divided into a plurality of areas (areas) and managed (recorded).

  Next, Step 2 is also a process for setting a precondition. In this embodiment, the distribution facilities installed in each divided area are classified and recorded so as to organize a maintenance / inspection group for each area. Note that information on workers constituting each maintenance / inspection group is held in the DB 130.

  Next, under the preconditions set in Step 1 and Step 2, in Step 3, the result of collecting the measurement information of the transmission / distribution system facilities by the distribution automation system or the like is stored in the DB 121.

Next, in Step 4, the priority order for each equipment is calculated according to the system information collected in Step 3 (the equipment priority order changes sequentially according to the state of the system after the work starts). Hereafter, Step4-1 ~
In Step 4-5, update the equipment priority.

  In Step 4-1, the level for each collected measurement value is determined for each preset equipment state measurement cycle from the measurement value level for each equipment type defined in the DB 123 and the abnormality detection level setting contents. In Step 4-2, the level of each measurement item obtained (determined) as a result of performing Step 4-1 is registered in the DB 121.

  Next, in Step 4-3, an abnormality occurs when it is detected that the measurement value level obtained in Step 4-2 is within the range of the measurement value abnormality level defined in DB 123 for each equipment state acquisition cycle. Count that the level has been detected, and register the number of abnormal level measurements in the DB 121 (in the case of the previous normal range). When the abnormal level is measured last time, the abnormal level continues, so the measurement signal abnormal level measurement time in the DB 121 is updated.

  In Step 4-4, refer to the DB 121 for the equipment in which anomaly was detected in Step 4-3, and for the equipment that has a redundant configuration (importance A), the measured value level is also set for the corresponding equipment that constitutes the redundant system. Confirm and go to Step 4-5 to update the priority.

  In Step 4-5, the priority order is updated according to the priority order update flow shown in FIG. 16 based on the information collected in Steps 4-1 to 4-4.

In Step 5, the maintenance / inspection route for the area in charge is created and updated for each maintenance / inspection group according to the priority order updated in Step 4-1 to Step 4-5 above. The work plan DB 125 for each maintenance / inspection group is corrected.
Next, a maintenance / inspection route update (work plan update) flow will be described with reference to FIG. FIG. 15 shows a flow for updating the maintenance / inspection route (work schedule DB 127) for carrying out maintenance / inspection for each group based on the priority order of equipment updated in accordance with the procedure described above. ing. Hereinafter, Step 6 to Step 27 in the flow illustrated in FIGS. 15A to 15C will be described.

  First, in Step 6, the following processing is performed based on the work plan DB 125 for each maintenance / inspection group calculated in Loop 1 in FIG. 14 using the measured values for each facility collected in Step 4 above. The contents will be described in step 7 and subsequent steps.

  In Step 7, regarding the equipment for which an abnormality has been confirmed in Step 6, whether the maintenance / inspection group in charge of the area where the equipment is installed is a technically applicable event, With reference to the technical level of each group worker registered in the DB 130 holding the information of the constituent workers, it is confirmed whether or not it is possible to cope.

  In Step 8, if it is confirmed that an abnormal level is recorded in the DB 124 or DB 126 as a result of the confirmation in Step 7, the technology required for handling according to the measured value level for each equipment type A maintenance / inspection group in charge of the area where the equipment in which the abnormal level is recorded is referenced with reference to the qualifications held for each worker, which are set in the DB 127 defining the level and the maintenance / inspection work plan DB 122 Step 9 to Step 19 are carried out below when technical support is possible.

  In Step 9, the state of the maintenance / inspection group in charge of the area where the facility where the abnormality is detected is installed is specified from the maintenance / inspection work plan DB 122 (working / out of work). As a specific method for determining the out-of-work state during work, for example, when an IC tag is attached to each equipment and accessed with a portable terminal or the like before starting the work, the equipment is in the work-in state and the work is completed. In addition, it is conceivable to notify the end of work by accessing again with a portable terminal or the like. Information indicating the result is recorded.

  In Step 10, if the maintenance / inspection group in charge of the area where the equipment where the abnormality is detected is out of operation as a result of the confirmation in Step 9, change the route instead of working on other equipment. Step 11 and subsequent steps described below are performed.

  In Step 11, compare the equipment importance of the equipment where the abnormality is detected and the equipment scheduled for initial work, and perform the corresponding processing among the contents described in Step 14, Step 16, and Step 18 according to the obtained results. .

  In Step 12, if the maintenance / inspection group in charge of the area where the equipment is installed is working on other equipment (confirming the priority of the equipment and responding), the following Step 13 and subsequent steps are performed.

  In Step 13, the importance of the equipment in which the abnormality is detected is compared with the equipment to be worked next, and according to the obtained result, the corresponding processing among the contents described in Step 14, Step 16, and Step 18 is performed.

In Step 14, when the equipment importance of the equipment in which the abnormality is detected is higher than the equipment importance scheduled to be worked next, the process proceeds to Step 15.
In Step 15, after performing the work of the facility in which the abnormality is detected, the maintenance / inspection work schedule DB 125 is modified so that the next work is performed.
In Step 16, when the importance level of the next scheduled equipment is equal to the importance level of the equipment in which the abnormality is detected, Step 17 is performed.

  In Step 17, the equipment priority order (in the DB 121) is compared, and the work schedule DB 125 is modified so that work on equipment having a high equipment priority order is performed with priority. This algorithm can be executed using a commonly used schedule adjustment algorithm.

  In Step 18, when the equipment importance level of the equipment in which the abnormality is detected is lower, Step 19 below is performed.

  In Step 19, as a result of comparing the facility importance in Step 18, if the facility importance of the facility in which the abnormality is detected is lower, the change to the work schedule DB 125 is not performed. Note that such a step is not actively provided, and if it is “low”, the process may be terminated as it is.

  In Step 20, when an abnormal level is recorded in DB 124 or DB 126 as a result of the confirmation in Step 7 above, refer to the technical level set in DB 127 and DB 123 and information on the qualifications held by each worker, If the maintenance / inspection group responsible for the area where the equipment where the abnormality is detected is technically difficult to respond, the following will be implemented.

  In Step 21, whether the maintenance / inspection group in charge of other areas can cope with the technical level is checked by DB 127 and DB 123.

  In Step22, if the technical level is applicable, check the work status (working / not working) of the extracted maintenance / inspection group that can be handled. Depending on the result of the confirmation, the contents described in Step 23 and Step 25 and thereafter will be implemented.

  In Step 23, the maintenance / inspection group extracted in Step 21 is stored in the DB 121 when the other area maintenance / inspection group that can support the technical level is out of work (the work of other equipment is not performed). Group having a short distance to the equipment is extracted from the position information. “Short distance” is determined as being closer (shorter) than the distance stored in advance. Moreover, you may extract the thing of several minutes used as the reference | standard memorize | stored previously from the nearest thing.

  In Step 24, the work schedule DB 125 is modified so that the work is performed in the group having the closest distance using the result extracted in Step 22 above.

  In Step 25, for the maintenance / inspection group extracted in Step 21, if another area maintenance / inspection group that can handle the technical level is working on other equipment, check the work priority according to the procedure described in Step 26 and below. .

  In Step 26, the facility importance of the facility in which the abnormality is detected is compared with the facility to be worked next. As a result, if the importance of the equipment in which the abnormality is detected is equal to or lower than the importance of the equipment to be worked on next, proceed to step 27 and have the same importance in the maintenance / inspection group extracted in step 21 The maintenance / inspection work plan DB 125 is modified so that the countermeasures are taken after completion of the corresponding remaining equipment.

  If it is judged as “High” in Step 26, proceed to Step 28 and perform the work on the equipment in the maintenance / inspection group extracted in Step 21. The maintenance / inspection work plan DB 125 is modified so that the work is performed.

Next, the contents of the priority order update flow will be described with reference to FIGS.
The equipment priority used in the maintenance / inspection route update (work schedule update) process shown in FIG. 15 is affected by the operating state of the power transmission and distribution system, and changes dynamically. Management makes it possible to carry out maintenance and inspections that better reflect the state of the transmission and distribution systems. In this figure, the update procedure of the equipment priority order reflecting the operation state of the power transmission and distribution system will be described.

  In Step 31, each power supply facility constituting the power transmission / distribution system stored in the power transmission / distribution facility monitoring situation DB 121 is defined in advance for each facility type defined in the measured value level and abnormality detection level setting DB 123 for each facility type. By comparing the abnormality detection level to be measured and the measured value for each power supply facility, the presence or absence of abnormality in the voltage / current value is confirmed.

  In Step 32, if there is no abnormality in the measured value as a result of the confirmation in Step 31, the maintenance / inspection work schedule DB 125 has the same contents as the DB 122 in order to carry out the work based on the originally planned maintenance / inspection work plan DB 122. Become.

  In Step 33, if there is an abnormality in Step 31 above, it is divided into a case where the abnormality has occurred at one place and a case where an abnormality has occurred at two or more places, and the following Step 34 to Step 45 In accordance with the contents described in, the facility priority order is updated according to the state of occurrence of abnormality in each facility.

  In Step34, when the occurrence of abnormality is detected in one facility on the system, the measured value level and abnormality detection level setting DB 123 for each facility type is referred to from the detected voltage / current value, and it occurs in the facility. Check the level of abnormality.

  In Step 35, the abnormality level for each equipment obtained as a result of the confirmation in Step 34 above and the equipment type / measured value defined in the technical level DB 127 required for the correspondence corresponding to the level for each equipment type are taken. The technical level required for maintenance / inspection set for each range is compared with the qualifications possessed by the workers of each maintenance / inspection group defined in the maintenance / inspection group configuration and work qualification DB 130, and the above Step 34 Check whether the abnormality confirmed in step 3 can be repaired or inspected by the maintenance / inspection group in charge of the area.

  In Step 36, if the abnormality is difficult to deal with at the technical level of the maintenance / inspection group in charge of each area as a result of the confirmation in Step 35 above, the maintenance / inspection is to be handled by a group that can be handled by other groups. The work schedule DB 125 is updated. When there are a plurality of groups that can be handled, a group having a short distance from the equipment is extracted from the position information held in the DB 121.

  On the other hand, in Step 37, if the result of the confirmation in Step 35 above indicates that the abnormality can be handled at the technical level of the maintenance / inspection group in charge of each area, priority is given to the maintenance / inspection of the equipment that detected the occurrence of the abnormality Then, the maintenance / inspection work schedule DB 125 is updated so as to be implemented.

  In Step 38, if there is an abnormality at two or more locations in Step 33 above, the importance A equipment (the importance A equipment is the equipment used for system linkage and must be configured with two or more multiplex systems. Adopt: here considers two systems) When there are abnormalities in two or more locations and there are multiple abnormalities in both systems (two or more locations), the equipment of importance level A according to the contents described in Step 41 to Step 44 Is calculated, and the transmission / distribution facility monitoring status DB 121 is updated using the obtained result.

  In Step39, if both system abnormalities have occurred in one importance A facility in Step33 above, the maintenance and inspection of the importance A facility in which the abnormality is detected has priority over other facilities. The equipment priority order is changed so as to be implemented, and the maintenance / inspection work schedule DB 125 is updated.

  In Step 40, if an abnormality has occurred in one system of importance A equipment in Step 33 above, maintenance and inspection should be performed in order from the equipment with the largest number of connected equipment to the equipment in which the abnormality has occurred. The equipment priority is changed and the DB 125 is updated. As with Step 38, when the number of connected facilities is the same, check the time when the abnormality occurred in each facility by DB 121, and give priority to the facility where the abnormality occurred at an earlier stage (equipment with a long abnormality duration). The maintenance / inspection work schedule DB 125 is updated so that the maintenance / inspection is performed.

  In step 41, if there are abnormalities in two or more locations in step 33 above, if abnormalities occur in two locations other than importance A, the operation is performed in the transmission / distribution facility monitoring status DB 121. The number of connected equipments in the state is confirmed, the equipment priority order is changed, and the DB 125 is updated so that maintenance / inspection is performed in order from the equipment with the largest number of connected equipments.

  In Step 42, in the above-mentioned facility priority update process, when a system abnormality is confirmed in the importance A facility, the DB 121 confirms (identifies) the connection destination area of the facility in which the system abnormality is confirmed.

  In Step 43, the presence / absence of other interconnection lines in the interconnection destination area of each system abnormality importance A facility detected in Step 42 is confirmed.

  In Step 44, if the result of the confirmation in Step 43 above indicates that there is no other interconnected line in the cooperation destination area, or there is an interconnected line, but cannot be used because of a failure during work, in Step 33 The confirmed connection destination area of the interconnection line in which the abnormality is recognized does not have the interconnection line (is not connected) and is isolated. When there are a plurality of such facilities, a comparison is made based on the number of connected facilities, the duration after the occurrence of an abnormality, and the like, and the priority of a facility with a large number of connected facilities or a facility with a long abnormality duration is set high. In this case, it is increased by a predetermined order.

  In Step 45, the connection relationship is confirmed in DB 121 for the connection destination of the interconnection line in which the abnormality confirmed in Step 33 is confirmed, and power can be supplied from other than the interconnection line in which the abnormality is recognized. If there is, the priority order is set so that the correspondence is performed after the correspondence to the importance A facility having no other interconnection destination area for which the priority order has been set in Step 44.

  As for the details of the processing of the embodiment of the present invention described above, examples (1) to (8) will be described below based on specific system configuration examples. In the following explanation of each case, it is assumed that DB is not shown, but data as described in the explanatory text is set (recorded).

Case (1)
This example is an example of a patrol / inspection route when there is no abnormality in the equipment that makes up the system. The daily maintenance / inspection route is established in advance for each inspection / inspection group in charge of each area. In this example, the inspection / inspection route is defined in advance for the four areas. In the equipment state (level) DB 124 before the start and the equipment state (level) DB 126 in operation, there is no abnormality indicating the equipment state, so the inspection work should be performed according to the route created before the start of the maintenance / inspection work. become.

Case (2)
This example is an example of inspection / inspection route when an abnormality is detected in each area before the work is started and the response within the group is possible (no abnormality after the work starts). Here, abnormalities that can be handled by the maintenance / inspection group in each area were detected in area 1 (equipment E106), area 2 (equipment E204), area 3 (equipment E307), and area 4 (equipment E403). In particular, describe in detail how the maintenance / inspection route will change.

  In area 1, it is assumed that an abnormality is detected at E106 before the work starts. Since E106 forms a redundant system with E107 here, it is equipment importance A. In this case, if there is an abnormality in the other equipment that makes up the redundant system (E107), assuming the worst case, the range of influence is large. Therefore, it is necessary to perform maintenance and inspection work with priority over other equipment. is there. Therefore, in the transmission / distribution equipment monitoring status DB, the priority order for each area-equipment importance level is changed to E106 priority order 1 for area 1 and E107 priority order 2 to E107 (E107 configures redundant system with E106) The inspection is performed at the same time because it is geographically adjacent), and the priority of each facility that was higher than the priorities 4 and 5 of E106 and E107 before the priority change was set to E106, The maintenance / inspection work route on the maintenance / inspection work plan DB 125 is updated so that the priority is lowered by two each so as to be implemented after the maintenance / inspection of E107.

  In area 2, an abnormality is detected at E204 before the work starts. E204 does not constitute a redundant system and is a single facility, but in this example, no other equipment in Area 2 has malfunctioned, so a maintenance / inspection work route was created. Sometimes, the priority of E204 is changed to 1 so that the maintenance / inspection of the equipment E204 is performed first, and the priority of each equipment that is higher than the priority 4 of E204 before the priority change is changed. The maintenance / inspection work route on the maintenance / inspection work plan DB 125 is updated so that the priority is lowered one by one so that the maintenance / inspection work is performed after the maintenance / inspection of E204.

  In area 3, an abnormality is detected at E307 before the work starts. E307 is not a redundant system, as is the case with E204, and is a single facility. However, in this case, there is no abnormality in other equipment in area 3, so maintenance and inspection are not necessary. When creating a work route, first change the priority of E307 to 1 so that maintenance and inspection work for equipment E307 is performed, and prioritize each equipment that has a higher priority than priority 7 of E307 before the priority change. The maintenance / inspection work route on the maintenance / inspection work plan DB 125 is updated so that the priority is lowered one by one so that the maintenance / inspection work is performed after the maintenance / inspection of E307.

In area 4, an abnormality is detected at E403 before the work starts. E403 is here
Since the redundant form is configured with E404, the equipment importance is A. In this case, in the same way as in area 1, if an error occurs in the other system that constitutes the redundant system, the power supply to area 3 that is the connection destination area will be hindered. Work needs to be carried out. Accordingly, in the power transmission / distribution facility monitoring status DB 121, the priority order for each area-equipment importance level is changed, the E403 priority order is changed to 1 for the area 4, the E404 priority order is changed to 2, and the E403 before the priority change is made. The maintenance / inspection work route should be set so that the priority of each equipment, which is higher than the priority of E404, E404, is lowered by two each so that the priority of each equipment is implemented after the maintenance / inspection of E403, E404. Update.

Case (2) -1
This case is an example in the case where an abnormality that can be dealt with within the own group occurs after the work starts in addition to the case (2). In the above case (2), a case where the maintenance / inspection route is determined within the group based on the equipment state information collected before the work starts is explained. In this case, additional equipment is added after the work starts. Consider the case where an abnormality occurs. Here, at the stage before the start of work, as shown in case (2), area 1 (equipment E106), area 2 (equipment E204), area 3 (equipment E307), and area 4 (equipment E403) An abnormality that can be handled by the maintenance / inspection group in each area is detected. Therefore, in the state before the start of work, as in the case (2), the maintenance / inspection work plan is updated and the maintenance / inspection work is started with priority given to the maintenance / inspection work of these facilities.

  Then, after starting work in the maintenance / inspection group in charge of each area, if a new abnormality occurs in equipment that was in a normal state at the time of work planning, the maintenance / inspection route established before the work starts is updated. There is a need. In this example, it is assumed that a new abnormality is detected after starting work at E108, E207, E313, and E402. In this case, E106 and E108 are both level 3 in area 1, but E106 is the equipment importance level. Since it is A, it is necessary to carry out maintenance and inspection in preference to other equipment. On the other hand, E108 has equipment importance B. Therefore, after priority is given to the maintenance and inspection of abnormal equipment in the order of E106 and E108, equipment priority is given to the maintenance and inspection of other normal equipment. The order needs to be changed, and the process of changing is executed in this way.

  In area 2, E204 abnormality is detected before starting work, but after starting work, abnormality is detected at E207. In this case, since the equipment importance of E207 is higher than the equipment importance of E204, and because E207 is a facility that adopts a redundant configuration, the equipment priority is set to 1 and 2 for E207 and E208, respectively. And the equipment priority of E204 is updated to 3.

  In area 3, the E307 abnormality is detected before the work starts. After the work starts, the maintenance / inspection work has already been performed once in E313. In this case, after the maintenance / inspection of E315 is completed, the maintenance / inspection of E313 is performed. Return to the maintenance / inspection work for the remaining equipment that was scheduled for maintenance / inspection work later.

  In area 4, an abnormality in E403 is detected before the work starts, but it is assumed that an abnormality has occurred in E402 after the maintenance and inspection work of E401 is completed after the work starts. Since E403 has a higher equipment priority than E402, the equipment priority is updated so that after E403 maintenance / inspection work, E402 maintenance / inspection work is carried out.

Case (3)
This example shows an example of a maintenance / inspection route when an abnormality that cannot be handled within the own group (it cannot be handled at the technical level of the own group) is detected before the work starts. Case (2) above shows the case where the maintenance / inspection group in charge of each area can deal with the abnormalities that occurred in each area, but the technical level of the workers in each maintenance / inspection group Therefore, depending on the type of abnormality that occurs in the equipment, it may be difficult for the maintenance / inspection group in charge of each area to handle it. When such a situation occurs, a maintenance / inspection group in charge of other areas that can be handled is extracted, and a review is carried out so that maintenance / inspection is carried out in a group that can handle (any It is always possible to respond in groups).

  An abnormality may occur in one facility or in two or more facilities at the same time. However, in this example, when an abnormality occurs in one facility, the abnormality occurs. Explains cases where it is difficult to deal with at the technical level of the maintenance / inspection group in charge of the area where the generated equipment is located, and describes cases (4) and later when an abnormality occurs in two or more equipment at the same time The explanation will be carried out.

In this example, a case where an abnormality occurs in area 1 and area 3 will be described as an example.
In area 1, an abnormality occurred in equipment E109. By referring to the equipment type DB 128 of each monitored equipment, it can be seen that the equipment E109 is equipment type 3. In addition, referring to the equipment state DB 124 before starting work, the state of the equipment E109 before starting work is a level 4 state. From this information and the technical level DB 127 required for handling according to the level for each equipment type. It can be seen that the qualification required for the maintenance and inspection of the equipment E109 is qualification 34.

  Here, looking at the maintenance / inspection group composition and work qualification DB 130, the maintenance / inspection group 1 in charge of area 1 is composed of maintenance / inspection workers A and B, but both have qualification 34. It is recorded that an abnormality occurring in the equipment E109 cannot be handled.

  On the other hand, in area 3, an abnormality occurred in equipment E319. With reference to the equipment type DB 128 of each monitored equipment, it can be seen that the equipment E319 is equipment type 4. In addition, referring to the equipment state DB 124 before starting work, the state of the equipment E319 before starting work is a level 3 state, and from this information, the technical level DB 127 required for handling according to the level for each equipment type is obtained. It can be seen that the qualification required for the maintenance and inspection of the equipment E319 is qualification 43.

  Here, looking at the maintenance / inspection group composition and work qualification DB 130, maintenance / inspection group 3 in charge of area 3 is composed of maintenance / inspection workers E and F, but both have qualification 43. Therefore, it can be determined that the abnormality occurring in the equipment E319 cannot be handled.

  In such a case, since the area 1 maintenance / inspection group cannot cope with the abnormality occurring in the area 1, first, a group having workers having the necessary qualification 34 is searched in the DB 130. Then, it turns out that only the worker C of the maintenance / inspection group 2 has the qualification. At this time, in this case, since the occurrence of abnormality is not confirmed in area 2, maintenance / inspection group 2 first gives priority to responding to the abnormality occurring in equipment E109 in area 1. Then, the DB125 maintenance / inspection work plan is changed so as to carry out the maintenance / inspection work in the area in charge of the own group (area 2) that was initially planned.

  Next, when a group having workers having the qualification (qualification 43) necessary for carrying out the maintenance work is searched for in the area 130, the maintenance / inspection group 1 It can be seen that the worker A and the worker H (only) of the maintenance / inspection group 4 have the qualification. At this time, in this example, the work state of the maintenance / inspection groups 1 and 4 in the area 1 and the area 4 is confirmed in the maintenance / inspection work plan DB 122, and the maintenance / inspection group 4 may be out of work. I understand. In this case, the maintenance / inspection group 4 first gives priority to responding to the abnormality occurring in the equipment E319 in the area 3, and then performs maintenance in the area in charge of the group (area 4) that was initially planned.・ Change (update) the maintenance / inspection work plan of DB125 to carry out the inspection work.

  Next, in addition to the case (3), a case (3) -1 showing an example in the case of newly detecting an abnormality after the start of work will be described.

  In this example, E109 abnormality was detected in area 1 before the start of maintenance / inspection work, and maintenance / inspection can be handled only by the area 2 support group. 1. The maintenance / inspection route in area 2 is being changed. In this state, it is assumed that an abnormality has occurred in the equipment type 3 E207 immediately after the work is started. The level of abnormality in E207 at this time is 3. In order to carry out the maintenance of this facility, the qualification 33 is necessary, and it can be confirmed from the maintenance / inspection group configuration and work qualification DB 130 that the worker D of the maintenance inspection group 2 has the qualification 33. On the other hand, level 4 abnormality occurred at E109 in area 1, but member worker A and worker B in area 1 maintenance / inspection group 1 do not have qualification 44 and It is difficult to respond to events. Here, since the worker C in the area 2 has the qualification 44, the work is carried out in the area 2 maintenance / inspection group 2. Here, as the equipment priority order, a redundant system is configured. (Equipment for cooperation with other systems) E207 / E208 in area 2 has priority, and then in order of E109 in area 1.

  In Area 3, Level 5 abnormality occurred at E319 before the work started and the equipment type of E319 is 4, so qualification 45 is required to perform maintenance and inspection of this equipment. It is. However, the area 3 maintenance / inspection group does not have the qualification 45, and only the area 4 maintenance / inspection group has the qualification 45. In area 4, an abnormality occurred after group 4 started work in E403, which is a redundant system, and the abnormality level is 5. Therefore, in the area 4 maintenance / inspection group, Execute maintenance / inspection work for E319, which has an abnormality before E403, and then change (update) the maintenance / inspection work schedule of DB125 to perform maintenance / inspection work for E403. To do.

  Next, a case (4), which is an example in the case where both system abnormalities occur at two places of importance A equipment before the start of work, and which can be technically handled within the own group, will be described.

  In cases (1) to (3) that have been described so far, there is one facility where an abnormality occurs, or even if an abnormality occurs in multiple facilities, the importance of each facility is different. Although there was no need to consider the priority order between facilities with the same importance, it is necessary to formulate a maintenance / inspection route in consideration of the priority when there are multiple facilities with abnormalities.

  In this example, a case where an abnormality occurs in two areas of importance A equipment in area 1 and area 4 will be described. Specifically, in area 1, two facilities are connected to area 3 consisting of facilities E106 and E107 and connected to area 2 consisting of facilities E112 and E113. Assume that both systems are abnormal. In this case, since an abnormality has occurred in a plurality of facilities having the same importance, the priority order of each facility is determined.

  Specifically, since there are two or more abnormal facilities in both systems, first, the presence / absence of an interconnection line in the interconnection destination area of each abnormal system is confirmed (Step 43). In this example, both abnormal systems in both systems are interconnected from area 1. In this example, all external power is supplied via area 1, so the current fault is occurring. The power supply to the areas 2 to 4 is not restored unless the system facilities are restored first. Therefore, although it progresses to step 44 here, by comparing here the case where maintenance / inspection order is determined according to the number of facilities of a connection destination area, and abnormal continuation time from the time when abnormality occurred in each interconnection line Two cases of determination are conceivable.

  In this example, considering the case where the setting is made to prioritize the number of connected destination facilities over the abnormality continuation time from the abnormality occurrence time, here, referring to the power transmission / distribution facility monitoring situation DB 121, the area 3 Since the number of facilities existing in 21 is 21 and the number of facilities existing in area 2 is 15, the maintenance / inspection priority of the interconnection line with area 3 is set higher than that of the interconnection line with area 2.

  In this case, level 3 abnormality occurred in equipment E106, E107, E112, E113 (equipment type 4) in area 1, so qualification 43 is required to carry out maintenance and inspection work. It is necessary, and the maintenance / inspection work plan DB122 has the qualification 43 for the worker A in the maintenance / inspection group 1. Therefore, the maintenance / inspection is carried out in the group 1 (the group in charge of maintenance / inspection in the area). It is possible to carry out the work.

  On the other hand, in the area 4, the level 3 abnormality is occurring in each of the single systems (equipment E406, E413) at the part linked to the area 2 (equipment E405, E406, E412, E413). In this case, the qualification 43 is required to carry out the maintenance / inspection work, and the maintenance / inspection work plan DB 122 has the qualification 43 in the maintenance / inspection group 4 worker H. It is possible to carry out maintenance and inspection work at 4.

  Next, Case (4) -1 is an example in which both system abnormalities occur at two or more places of importance A equipment before the work starts, and it is technically impossible to cope with within the own group. . Here, a case will be shown in which, when an abnormality in both systems occurs in the importance A facility in area 1, it is difficult for the area 1 maintenance / inspection group to cope with both system abnormalities in the own group. In this example, when an abnormality is detected in a plurality of facilities having the same importance, a case will be described in which priority is determined based on an elapsed time since the occurrence of the abnormality.

  In area 1, an abnormality has occurred in facilities E106, E107 and facilities E112, E113, which are facilities of facility type 4 constituting facilities of importance A. The occurrence of an abnormality is a situation where a level 5 abnormality has occurred in both systems (E106, E107), (E112, E113). At this time, the maintenance / inspection group 1 in charge of the area 1 does not have the technical level 45 corresponding to the abnormality of the level 5 in the equipment type 4 and therefore cannot cope with it. Here, when the maintenance / inspection group in charge of other areas is confirmed, only the maintenance / inspection group 4 in charge of area 4 has the qualification 45, and the importance A facilities E106, E107, E112, It is possible to deal with abnormalities in E113. Therefore, here, the maintenance / inspection route is changed so that the maintenance / inspection group 4 in charge of area 4 performs the maintenance of the facilities E106, E107, E112, E113.

  In addition, about the priority of each importance A equipment, when the elapsed time after the occurrence of an accident (abnormality) in each equipment is observed (acquisition from the power transmission / distribution equipment monitoring status DB 121), the equipment E112 and E113 each have 50 minutes. It can be seen that the abnormal state continues for 55 minutes, while the facilities E106 and E107 both continue to be abnormal for 30 minutes. Therefore, in this example, the maintenance / inspection work for the facilities E112 and E113 is performed with priority over the facilities E106 and E107.

  Next, Case (5) is a case where a malfunction of both systems has occurred at one place of importance A equipment, and the own group cannot technically cope with it. Here, a case where an abnormality has occurred in facilities E319 and E320, which are facilities for interconnection with area 4 in area 3, is shown.

  Level 3 abnormalities have occurred in equipment E319 and E320, respectively, and equipment type of equipment E319 and E320 is 4, so technical level 43 is required to perform maintenance and inspection. -Since inspection group 3 does not have technical level 43, it is necessary to deal with other maintenance / inspection groups that possess technical level 43. Here, referring to the maintenance / inspection group configuration and the work qualification DB 130, it can be seen that the maintenance / inspection group 1 or the maintenance / inspection group 4 has the qualification. In this case, it is necessary to determine which of the maintenance / inspection group 1 through maintenance / inspection group 4 listed above is appropriate to carry out the maintenance / inspection work for equipment E319, E320. The current work status for each maintenance / inspection work group is held in the inspection group configuration and work qualification DB 130.

  In this case, confirming the status of Group 1 and Group 4 when the occurrence of an abnormality is detected in facilities E319 and E320, Group 1 is working and Group 4 is out of work (moving). is there. Therefore, in this example, the maintenance / inspection work schedule of the DB 125 is changed (updated) so that the maintenance / inspection work of the facilities E319 and E320 is performed in the group 4.

  So far, in case (4) -1 and case (5), when both system abnormalities have occurred at two or more places of importance A equipment, and both systems abnormality has occurred at one place of importance A equipment In the case of occurrence, explanations have been given for cases in which it is difficult for the own group to respond. Next, as an example (6), when an abnormality is detected in one system in a plurality of importance A facilities constituting a redundant system, specifically, an example in which an abnormality is detected in E308 and E320 is explained. To do.

  Here, a case will be described in which an abnormality is detected in E308 and E320 constituting the interconnection facility with another system in area 3.

  In this example, referring to the power transmission / distribution facility monitoring situation DB 121, it can be seen that E308 and E320 have level 3 abnormalities at the same time. In this case, the abnormal continuation time is obtained from the power transmission / distribution equipment monitoring status DB 121 and compared. However, since both are abnormal continuations for 30 minutes, the number of equipments in the area to which each equipment is connected (the number of influential equipments). Make a comparison. Specifically, since E308 is equipment related to connection to area 1, the number of equipment in area 1 is 14, and E320 is equipment related to connection to area 4, so area 4 The number of facilities will be affected, and it can be seen that E320 is more important here. Here, the area 3 maintenance / inspection group 3 has the necessary qualifications to carry out the maintenance / inspection of E308 and E320. After carrying out maintenance and inspection with priority in order, change so that other normal equipment is repaired and inspected.

  Case (6) -1 describes a case where a one-system abnormality has occurred in two areas of importance A equipment within area 3. Specifically, level E5 and level E320 are detected for level 5 and level 3 abnormalities, respectively, and among the detected abnormalities, E308 level abnormalities can be handled within group 3. On the other hand, regarding the level of abnormality detected for E320, it is difficult to cope with within Group 3, and other groups possessing the technical level necessary for maintenance and inspection (specifically, Group 1 or Group The maintenance / inspection schedule will be updated so that the response in 4) can be implemented.

  Here, in order to confirm which of Group 1 and Group 4 is available, refer to the maintenance / inspection group configuration and work qualification DB 130. For maintenance / inspection group 1, maintenance / inspection is in progress. Since the group 4 is moving, the maintenance / inspection work schedule of the DB 125 is changed (updated) so as to correspond to the group 4 here.

  Next, Case (7) -1 will be described.

  This example is for the maintenance / inspection group in charge of each area when an abnormality is detected in facilities of importance B to E (no linkage with other systems) existing in each area before the work starts. This is an example of a case where it is possible to cope with the problem.

  As described above, facilities of importance B to E are not related to interconnection with other systems, and power is supplied in conjunction with other facilities in the system where each facility is installed. Equipment. When it is said that the occurrence of an abnormality is detected in these facilities, it is necessary to prioritize the maintenance / inspection of the facility in which the abnormality is detected. In this case, the priority order of equipment repair / inspection is determined in the following two stages. .

  In area 1, it can be seen from the power transmission / distribution facility monitoring status DB facility DB 121 that level 3 anomalies occur simultaneously in facilities E108 and E114. In this case, confirming the importance of each equipment, the importance of equipment E108 (equipment type 1) is B, and the importance of equipment E114 (equipment type 2) is D. Carry out inspections, and then repair and inspect equipment that has not failed. In addition, Group 1 in charge of maintenance / inspection in area 1 has qualification 13 and qualification 23 when referring to the maintenance / inspection group configuration and work qualification DB 130. Inspection can be carried out.

  In area 2, each level before the start of work at facilities E204 (equipment type 2), E210 (equipment type 1), E212 (equipment type 2) (equipment importance of each facility is D, C, D respectively) In this case, the maintenance / inspection for the equipment E210 is prioritized, and then the maintenance / inspection for the equipments E204, E212 is performed. Since the equipment importance level and the level of abnormality are the same for the facilities E204 and E212, when the abnormality duration is confirmed by the power transmission / distribution facility monitoring status DB facility DB 121, the abnormality duration of the facility E204 is 30 minutes and the facility E212. In this case, the maintenance / inspection work schedule of the DB 125 is changed so that the maintenance / inspection for the equipment E204 is prioritized. In Group 2, which is in charge of maintenance / inspection in area 2, referring to the maintenance / inspection group configuration and work qualification DB 130, maintenance / inspection worker D has qualification 14 and qualification 23. Maintenance and inspection can be carried out within the group.

  In area 3, each of the equipment E313 (equipment type 1), E317 (equipment type 1), and E318 (equipment type 5) (equipment importance level of each equipment is C, C, E, respectively) before starting the work. In this case, for the facilities E313 and E317, the abnormality durations are compared, and the priority of the facility having a long duration is changed to be higher. Here, an abnormality occurred 20 minutes before in E313, and an abnormality occurred 10 minutes before in E317. Therefore, the maintenance and repair of DB125 is performed so that inspection inspections for abnormality detection are performed in the order of facilities E313, E317, and E318. Change the inspection work schedule. In the maintenance / inspection group 3 in the area 3, since the worker E has the qualification 53 and the worker F has the qualification 13, the maintenance / inspection can be carried out within the own group.

  In area 4, since each level 3 abnormality is detected in equipment E407 (equipment type 3), E410 (equipment type 3) (equipment importance of each equipment is both importance B), in this case As in the area 3, for the facilities E407 and E410, the abnormal durations are compared and the priority of the facility having a long duration is changed to a higher priority. Here, when the abnormal continuation time is confirmed by the power transmission / distribution equipment monitoring status DB equipment DB 121, the abnormality is detected in the order of equipment E407 and E410 because E407 is an abnormal continuation for 30 minutes and E410 is an abnormal continuation for 20 minutes. The maintenance / inspection work schedule of the DB 125 is changed so that the inspection inspection is performed.

  Next, Case (7) -2 will be described. This example is a maintenance / inspection group in charge of each area when an abnormality is detected in facilities of importance B to E (not linked to other systems) existing in each area before the work starts. This section explains how to determine the inspection route of the maintenance / inspection group in charge of each area when it is impossible to cope with the level of technology / skill held by.

  Each maintenance / inspection group is generally considered to be composed of multiple workers in order to ensure safety during work. Each worker possesses various technologies and skills necessary for inspection and inspection of power transmission and distribution facilities. However, each worker's technology and skills are subject to individual differences, working conditions, etc. Therefore, there may be variations in the types of equipment abnormalities that can be handled by each maintenance / inspection group.

  Based on the above assumptions, the description of this example will be described below.

  Here, as in the case (7) -1, let us consider a case where an abnormality is detected in facilities of importance B to E (no connection with other systems) existing in each area. At this time, it is difficult to repair and inspect the anomalies that occurred in the facilities and equipment in each area at the level of technology and skills possessed by the maintenance and inspection group in charge of the area where the anomaly occurred. In such a case, the maintenance / inspection route of each maintenance / inspection group will be reviewed according to the following procedure so that the maintenance / inspection group in charge of other areas will take action. Here, in this case, the technology necessary for maintenance / inspection is always possessed by any maintenance / inspection group for various abnormal conditions that occur in the power system, and all the responses to the events that have occurred are held. It is based on the premise that there is no such situation as impossible in the maintenance and inspection group.

  Under the above conditions, a case will be described below where, in the area 1, it is found (recognized) by referring to the power transmission / distribution facility monitoring status DB 121 that an abnormality has occurred in the facilities E108 and E114. In such a case, each maintenance / inspection group's technologies and skills and each equipment should be inspected so that the equipment that detected the occurrence of each abnormality has a patrol inspection with priority over other equipment that does not show any abnormality. The priority is updated according to the following procedure by comparing with the abnormality that has occurred.

  The facility E108 has a facility type of 1 and a level 4 abnormality has occurred. In this case, referring to the DB 122, first, a maintenance / inspection group capable of dealing with an abnormality occurring in each facility is searched. For workers in the area 1 maintenance / inspection group 1, referring to the maintenance / inspection group configuration and the work qualification DB 130, they do not have the qualification 14 and cannot cope with the abnormality occurring in the equipment E108. Therefore, when the presence or absence of a worker who can be handled by another worker in the maintenance / inspection group is confirmed, it can be seen that the worker D in the maintenance / inspection group 2 has a technology that can be handled. However, since the maintenance / inspection group 2 is currently in operation, the maintenance / inspection work schedule of the DB 125 is changed so that the abnormality detection facility E108 is repaired / inspected after completion of the operation.

  In the maintenance / inspection group 2, abnormalities are detected in the facilities E204, E210, and E212, and the priority order is determined by comparing these facilities with the level of the abnormality that has occurred in the facility E108. To do. Here, the importance of the equipment E108 is A, the importance of E204 is D, the importance of the equipment E210 is C, and the importance of E212 is D, so the equipment E108, E210, E204, E212 are repaired in this order. After the inspection, the maintenance / inspection work schedule of the DB 125 is changed so that the other facilities in the area 2 are repaired / inspected.

  Furthermore, in the maintenance / inspection group 3, abnormalities are detected in the equipments E313, E317, and E318. However, for E313 and E317, the equipment type is 1 and the abnormality level is 3, so the maintenance and inspection work is performed. Personnel F can carry out maintenance / inspection work, but E318 has equipment type 5 and the level of abnormality is 4, so in area 3 maintenance / inspection group 3, maintenance / inspection of the equipment concerned We do not have the technical level necessary to carry out the inspection. Therefore, referring to the DB 122 and confirming the technical level possessed by another group, it can be seen that the technical level 54 is possessed by the maintenance / inspection group 4 corresponding to the area 4 and that it is possible to cope with it. In area 4, level 3 abnormality occurred in equipment E407, but the level of abnormality occurring in area 3 is higher, so equipment E318 has priority over equipment E407. -Change the maintenance / inspection work schedule of maintenance / inspection group 4 to carry out inspections, and transfer the work to maintenance / inspection group 4 for equipment E318 above for maintenance / inspection group 3 It becomes.

  Next, Case (8) -1 will be described. Here, a specific description will be given of a case where both system abnormalities occur at two places of importance A equipment before the work starts. Here, a system in which area 5 is added to the systems of cases (1) to (7) used for the explanation of the cases so far will be considered.

  In this example, when the occurrence of an abnormality is confirmed in two places of importance A equipment before the start of work, and there are other interconnection lines in the connection destination area, the connection destination area of the equipment in which the abnormality has occurred Compare the impact on Specifically, when an abnormality occurs in the interconnection line, if there is another interconnection line to the connection destination area, go to an area where there is no other interconnection line to the connection destination area. A maintenance / inspection schedule is created so that maintenance / inspection of connected interconnections is prioritized.

  In the system of this example, in area 3, the facilities E314 and E315 and the facilities E319 and E320 are connected to the interconnection facilities E504 and E505 in the area 5 and the interconnection facilities E403 and E404 in the area 4, respectively. ing. In such a system configuration, both system abnormalities occur in the equipments E314 and E315 and the equipments E319 and E320, and the equipment E415 in the area 4 constituting the interconnection line connecting the areas 5 and 4 is provided. As a procedure for determining the priority order of the equipment in area 3 when an abnormality occurs in E416, first of all, the equipment (E314, E315) As a result of extracting (E319, E320), it can be seen that there is a connection relationship with area 5 and area 4, respectively.

  Next, for the area 4, in addition to the facilities (E403, E404) that have a connection relationship with the area 3, the facilities that have a connection relationship with other areas are checked by the transmission / distribution facility monitoring status DB, which is the DB 121. E405, E406), it is found that there is a connection relationship with the equipment (E207, E208) in area 2 and it is valid (no abnormality is generated). Also, it can be seen that area 2 is connected to the facilities (E112, E113) in area 1 at the facilities (E202, E203) and is also effective. From this, it can be understood that the power supply to the area 4 is not all stopped due to the abnormality of the facilities (E319, E320). On the other hand, with regard to area 5, the grid connection equipment (E415, E416) that links area 5 and area 4 is abnormal in both systems, so the maintenance and inspection work for the equipment (E314, E315) is given priority. It turns out that it is necessary.

  In the case (8) -1, the case where the power supply to the connection destination area is stopped when an abnormality occurs in a plurality of facilities of importance A is explained. A case where power supply to the previous area can be performed via another interconnection line will be described.

  In the system shown in this example, in area 3, the facilities (E314, E315) and the facilities (E319, E320) are connected to the facility for interconnecting (E504, E505) in area 5, and the facility for interconnecting in area 4 ( E403, E404). In the case of such a system configuration, and when other interconnection facilities are normal, the facility priority order determination procedure in area 3 when power supply is possible is as follows. As a result of extracting the equipment (E314, E315) and (E319, E320) as equipment having connection relations with other areas among the equipment constituting 3, it is understood that there is a connection relation with areas 5 and 4 respectively. .

  Next, for the area 4, in addition to the facilities (E403, E404) that have a connection relationship with the area 3, when the facilities that have a connection relationship with other areas are extracted from the transmission / distribution facility monitoring status DB registration information that is the DB 121, the facility (E405, E406) or equipment (E412, E413), it can be seen that the equipment (E207, E208) and equipment (E214, E215) are connected and effective. It can also be seen that area 2 is effective because it is connected to the facilities (E112, E113) in area 1 by the facilities (E202, E203).

  From this, it is understood that the power supply to the area 4 is not all stopped due to the abnormality occurring in the area 3 facility (E319, E320). On the other hand, in the area 5, the system linkage facilities (E415, E416) and (E510, E511) that link the areas 5 and 4 are in a normal state, and due to an abnormality occurring in the facilities (E314, E315), the area 5 It turns out that it is not the situation where the power supply to is stopped.

  In this case, the maintenance / inspection work is performed with priority given to the equipment having a long abnormal duration among the equipment (E314, E315) and the equipment (E319, E320). Here, the measurement in the power transmission / distribution equipment monitoring status DB 121 is performed. Check the signal abnormality level duration, and the elapsed time (40 minutes) after the abnormality detection of the equipment (E319, E320) is longer than the abnormality detection time (20 minutes) of the equipment (E314, E315). It can be seen that the maintenance and inspection work of (E319, E320) should be prioritized.
