Description

  Embodiments described herein relate generally to a power system monitoring control system and a power system monitoring control program for monitoring a power system from a remote location.

  In the power system monitoring and control system, monitoring control of power system facilities is performed based on a facility database, which is a database related to power system facilities. When there is a change in the power system equipment, the current equipment database is updated, and the changed equipment database is stored in a storage area different from the current equipment database. About the equipment database after a change, the operation check using the monitoring control function simulated in the test part is performed. If it is confirmed by the operation check that the equipment database has been correctly changed, the equipment database after the change is operated in the power system monitoring system.

  When the operation based on the changed equipment database is performed, first, the monitoring and control of the power system by the monitoring control unit based on the current equipment database is ended. And the equipment database after a change is read, and monitoring and control of the electric power system by the monitoring control means based on the equipment database after a change are restarted.

  Therefore, it takes time to start the monitoring control of the power system based on the changed equipment database, and there is a possibility that a temporary blank may occur in the monitoring control of the power system. Therefore, conventionally, by switching a plurality of monitoring control means and starting monitoring control of the power system based on the changed equipment database, the monitoring control of the power system based on the current equipment database is ended. The monitoring control was continuously operated.

  In recent years, power system monitoring in which a plurality of operation bases, a plurality of monitoring control servers, and a maintenance server are connected via a network, and each monitoring control server shares a jurisdiction operation base and performs monitoring control in a wide area. A control system is adopted. In such a configuration, when there is a change in the power system equipment at some operation bases, and monitoring control based on the changed equipment database is performed, monitoring control is temporarily stopped at all the operation bases. There was a need. For this reason, every time there is a change in equipment at each operational site, the monitoring control function of the power system is temporarily impaired at all operational sites. However, if the monitoring control server is provided so as to be switchable at all operation bases, the configuration of the monitoring control system becomes complicated.

  In the power system monitoring system, operation bases managed by each monitoring control server are set in advance. Since the maintenance server manages the power system equipment of each operation base in association with the monitoring control server that has jurisdiction over the power system equipment, the monitoring control server could not monitor and control the operation base outside the jurisdiction .

  On the other hand, when a monitoring control server at a certain operating base fails due to a disaster such as an earthquake, it is desired that another monitoring control server monitor and control the operating base instead of the failed monitoring control server. However, the change of the equipment database is appropriately performed at each operation base, and the equipment database after the change at all the operation bases is configured so that each monitoring control server grasps as needed. It was not realistic from an economic point of view.

  The embodiment of the present invention has been proposed in order to solve the above-described problems of the prior art. Its purpose is to provide a power system monitoring control system and a power system monitoring control program that prevent the monitoring control function of the power system from being impaired and also enable the monitoring control server to monitor and control operation bases outside the jurisdiction.

The supervisory control servers 1A to 1E share the supervisory control of a plurality of power system facilities by setting only the power system facilities of the operation bases 2A to 2E having jurisdiction as targets of the supervisory control. However, a plurality of operation bases may share one power system facility. In this case, one jurisdiction operation base for the power system equipment is determined, but the operation base sharing the power system equipment also performs monitoring control.

  As shown in FIG. 1, the monitoring control servers 1 </ b> A to 1 </ b> E include a monitoring control unit 11, a monitoring control information storage unit 12, an equipment DB switching unit 13, an active equipment DB storage unit 14, and an integrated equipment DB storage unit 15. The test facility DB storage unit 16 and the test unit 17 are provided.

The monitoring control unit 11 has a function of monitoring a state change of the power system facility within the jurisdiction range and performing a remote operation and control including stop and restart of the operation of the power system facility by a control command. The monitoring control unit 11 obtains information about the power system from the remote monitoring control unit included in the operation bases 2A to 2E, or outputs a control command to the remote monitoring control unit.

  The monitoring control information storage unit 12 is a storage unit that stores information about the power system obtained by the monitoring control unit 11 from the remote monitoring control means of the operation bases 2A to 2E. The information related to the power system includes information indicating the device status related to the power system facility under the jurisdiction. The facility DB switching unit 13 stores the modified facility data in the integrated facility DB storage unit 15 when the facility database is changed in the maintenance server M, and integrates the monitoring control unit 11 from the current facility DB storage unit 14. It is a processing unit that outputs a command to switch the facility database to be referenced to the facility DB storage unit 15. The facility DB switching unit 13 is also a processing unit that stores the changed test facility data in the test facility DB storage unit 16 when the test facility database is changed in the maintenance server M.

  The working facility DB storage unit 14 is a storage unit that stores a working facility database related to the current power system facility. At the start of operation of the power system monitoring control system, the monitoring control unit 11 of the monitoring control servers 1A to 1e performs monitoring control of the power system facility based on the current facility database stored in the current facility DB storage unit 14. The integrated facility DB storage unit 15 is a storage unit that stores a facility database integrated by the maintenance server M.

  The test facility DB storage unit 16 is a storage unit that stores a test database that is a modified facility database created by the maintenance unit 20. The test unit 17 is a processing unit that tests the test database stored in the test facility DB storage unit 16. The test unit 17 reads the test facility database stored in the test facility DB storage unit 16 in response to an input from the monitoring control console C. The test unit 17 has a function of simulating a power system based on the changed test facility database and performing monitoring control. By the simulated monitoring control, the operator confirms whether the equipment database is correctly changed.

(3) Operation base Each of the operation bases 2A to 2E includes a plurality of power system facilities. The operation bases 2A to 2E have remote monitoring control means (not shown). The remote monitoring control unit has a function of outputting the control command output by the monitoring control unit 11 of the monitoring servers 1A to 1E to the power system. The remote monitoring control unit has a function of transmitting data obtained by monitoring or measuring information about the power system to the monitoring control unit 11.

  As shown in the schematic diagram of FIG. 3, the operation bases 2A to 2E may be configured to share some power system facilities. For example, the power system facility E is a shared facility that can be monitored and controlled by the operation bases 2A and 2C. For example, even if the jurisdiction operation base is 2A, the power system equipment E is monitored and controlled by the workers at the control centers of both the operation bases 2A and 2C. That is, there is a case where an input such as a change of the power system equipment E is performed to the maintenance server M from the maintenance console D of both the operation bases 2A and 2C.

(4) Maintenance Server The maintenance server M is a processing unit that performs the following processing when there is a change such as addition of a power system facility.
(A) Create a new equipment database based on the current equipment database.
(B) The created equipment database is transmitted to the designated monitoring control servers 1A to 1E.
(C) Integrate the equipment database after the test.
As illustrated in FIG. 4, the maintenance server M includes a maintenance unit 20, a transmission unit 30, and a database integration unit 40.

(A) Maintenance Unit The maintenance unit 20 is a processing unit that creates a new equipment database based on the current equipment database. The maintenance unit 20 includes an active facility DB storage unit 21, an facility DB change unit 22, a change data extraction unit 23, and a test facility DB storage unit 24. The working facility DB storage unit 21 is a storage unit that stores a working facility database related to the current power system facility.

  The facility DB changing unit 22 is a processing unit that updates the current facility database when the power system facility is changed. In response to a command from the maintenance table D, the facility DB changing unit 22 reads the current facility database stored in the current facility DB storage unit 21 and displays it on the maintenance table D, for example. The operator makes changes to the working equipment database via the maintenance console D. The equipment DB changing unit 22 updates the equipment database according to the change from the maintenance console D, outputs it to the changed data extracting unit 23, and stores it in the test equipment DB storage unit 24.

  The change data extraction unit 23 is a processing unit that extracts change data from the working facility database changed by the facility DB changing unit 22. The change data extraction unit 23 compares the current facility database stored in the current facility DB storage unit 21 with the facility database input from the facility DB change unit 22, and extracts change data that is the difference between the two databases. To do. For example, when the generator is added on January 1 at the operation base 2A, “January 1, generator A, operation base 2A jurisdiction, operation base 2A monitoring, addition, rating, etc. The data may include data including “equipment information”.

  The facility information such as the rating is stored in a storage unit (not shown), and when the change of the power system facility is input from the maintenance console D, the facility DB changing unit 22 reads from the storage unit. be able to. The test facility DB storage unit is a storage unit that stores the changed facility database.

  Specifically, for example, it is confirmed whether a generator is added, the coefficient of the generator is displayed on the screen of the monitoring control console C, whether the monitoring control of the generator is correctly performed, or the like. When the test of the equipment database after the change is completed and the operator inputs on the maintenance table D that the equipment database after the change is integrated, the change data extracted by the change data extraction unit 22 is sent to the database integration unit 40. Is output.

(B) Transmission unit The transmission unit 30 monitors the changed facility database stored in the test facility DB storage unit 24 and the integrated facility database stored in the integrated facility DB storage unit 43. It is a processing unit to transmit to the equipment DB switching unit 13 of ~ 1E. The transmission unit 30 outputs the changed equipment database or the integrated equipment database to the equipment DB switching unit 13 based on a command from the monitoring control console C.

(C) Database Integration Unit The database integration unit 40 is a processing unit that integrates the equipment database after the test. The database integration unit 40 includes an operation start date extraction unit 41, an integration unit 42, and an integrated facility DB storage unit 43. The operation start extraction unit 41 is a processing unit that extracts an operation start date included in the change data input from the change data extraction unit 22. For example, if the change data includes information such as “January 1, generator A, operation base 2A jurisdiction, operation base 2A monitoring, facility information such as addition, rating, etc.”, January 1 is extracted.

  The integration unit 42 is a processing unit that integrates the working facility database and the change data in time series. For example, if the current equipment database includes an equipment database whose operation start date is up to December 31, the change data including the operation start date on January 1 is integrated so that it comes next to the equipment data on December 31. Is done. The integrated facility DB storage unit 43 is a storage unit that stores an integrated facility database.

[2. Action]
(1) Database Update / Test / Integration A flow relating to the facility database update, test, and integration in the power system monitoring and control system in the present embodiment as described above will be described with reference to FIG. When there is a change in the power system equipment, the worker refers to the equipment database stored in the working equipment DB storage unit 21 and inputs a change to the working equipment database via the maintenance console D (step S01). The facility DB changing unit 22 creates a changed facility database and stores it in the test facility DB storage unit 24 (step S02).

  FIG. 6 schematically shows processing performed by the maintenance unit 20. In the maintenance unit 20, every time a change of the power system facility is input from the maintenance console D, the facility DB change unit 22 updates the working facility database. In FIG. 6, the input change is shown as change data for convenience of explanation. When the current equipment database is updated with the change data 1, the changed equipment database is set as the generation 1 equipment database.

  When the change data 2 is input after the generation 1 facility database is created, the generation 1 facility database is updated with the change data 2 to create the generation 2 facility database. The facility database of each generation may be stored in the test facility DB storage unit 24 and read and updated by the facility DB change unit 23. Moreover, it is good also as a structure which preserve | saves the equipment database of each generation in temporary memory | storage parts, such as RAM.

  The changed facility database is transmitted to the facility DB switching unit 13 of the monitoring control servers 1A to 1E by the transmitting unit 30. As shown in FIG. 1, the facility DB switching unit 13 causes the test facility DB storage unit 16 to store the modified facility database.

  The test unit 17 reads the modified facility database stored in the test facility DB storage unit 16, and performs monitoring control by simulating the power system (step S03). When the operator confirms the test contents and determines that there is a problem in the changed equipment database (NO in step S04), the process returns to step S01, changes the current equipment database again, and repeats steps S02 to S04.

  On the other hand, if the operator confirms the test contents and determines that the changed equipment database has been correctly changed, an input is made to integrate the changed data via the maintenance console D (step S04, YES). Then, the change data extraction unit 23 compares the current equipment database with the changed equipment database, and extracts change data that is a difference between the two databases (step S05). The extracted change data is input to the database integration unit 40.

  The operation start date extraction unit 41 extracts an operation start date included in the input change data (step S06). The integration unit 42 integrates the working facility database and the change data in time series (step S07). The integrated equipment database is stored in the integrated equipment DB storage unit 43.

  FIG. 7 schematically shows processing performed by the database integration unit 40. First, as an initial condition, the working equipment database is obtained by integrating the equipment databases of the operation bases 2A to 2E in time series. The equipment database changed in each operation base is tested at any time by the test unit 17 of the monitoring control servers 1A to 1E. When the operator inputs that the equipment database has been tested, the change data is extracted from the changed equipment database.

  In the database integration unit 40, the operation start date is extracted from the change data. For example, it is assumed that the operation start date of the information related to the power system equipment included in the working equipment database, which is the initial value, is December 31, 2014. In this case, for example, if the operation start date of the change data 1 of the operation base 2A is January 2, 2015, the change data 1 is added after the data whose operation start date is December 31, 2014. The

  Further, if the operation start date of the change data 2 of the operation base 2B is January 1, 2015, the operation start date is next to the data of December 31, 2014, and the change data 1 of the operation base 2A Before, the change data 2 of the operation base 2B is added. That is, when the information regarding the operation start date of the change data integrated later is earlier than the change data integrated earlier, the change data integrated later becomes the change data integrated earlier. As such, they are rearranged and integrated in time series.

  An example of the equipment database integrated as described above is shown in FIG. As shown in FIG. 8, in the integrated equipment database, information on the power system equipment of each operation base is integrated in time series in order of the operation start date. The monitoring control servers 1A to 1E perform monitoring control of the power system equipment using the integrated equipment database. The integrated facility database shown in FIG. 8 is stored in the integrated facility DB storage unit 15 of the monitoring control servers 1A to 1E and the integrated facility DB storage unit 43 of the maintenance server M, respectively.

(2) Switching of facility database When the facility database used for monitoring control is changed, the monitoring control unit 11 of the monitoring control servers 1A to 1E ends the monitoring control based on the current facility database. Upon receiving the switching command from the facility DB switching unit 13, the monitoring control unit 11 reads the modified facility database from the integrated facility DB storage unit 15, and resumes the monitoring control based on the integrated facility database.

  After switching from the working facility database to the integrated facility database, the monitoring control unit 11 manages the integrated facility DB storage unit 15 as the working facility DB storage unit. The active facility DB storage unit 14 is managed as an integrated facility DB storage unit. That is, when there is a further change in the equipment database after switching, the equipment database integrated in the working equipment DB storage unit 14 is stored. Thus, the role of the working facility DB storage unit 14 and the integrated facility DB storage unit 15 is switched every time the facility database is changed.

(3) Change of integrated equipment database When the monitoring control based on the integrated equipment database is resumed in the monitoring control servers 1A to 1E, the maintenance equipment M stores the integrated equipment stored in the integrated equipment DB storage unit 43. The database is stored in the working facility DB storage unit 21. If there is a further change in the equipment database after switching, the equipment DB changing unit 22 reads the integrated equipment database stored in the active equipment DB storage unit 21 and makes a change.

  That is, as shown in the schematic diagram of FIG. 9, the workers at the operation bases 2A to 2E read out the integrated equipment database stored in the working equipment DB storage unit 21 as the generation 5 equipment database, respectively, and the equipment DB changing unit 22 generates the generation. 5 The equipment database is changed and stored in the test equipment DB storage unit 24. Then, it is assumed that a test is performed at each of the operation bases 2A to 2E, and an operator inputs that the operations are to be integrated at each operation base. In that case, the operation start date of the change data 6-10 extracted by the change data extraction unit 23 is extracted, and the integration unit 42 extracts the data included in the generation 5 facility database and the change data 6-10 in time series. Rearrange and integrate.

[3. effect]
The effects of the present embodiment as described above will be described below.
(1) In the power system monitoring control system of the present embodiment, the integration unit 42 integrates the change data into the equipment database in time series based on the information about the operation start date extracted by the operation start date extraction unit 41. Accordingly, it is possible to obtain facility data in which information on power system facilities at a plurality of operation bases is integrated. Therefore, the facility database can be switched at a time at all operation bases. Compared to the conventional power system monitoring control system that switches the facility data by stopping the monitoring control function at all operation bases whenever there is a change in the equipment database, it is possible to suppress the damage to the power system monitoring control function. .

  In the power system monitoring and control system, the worker changes and tests the equipment database, for example, several months ago, and integrates the changed data, aiming for a future operation start date. For example, integration of change data having an operation start date of January 1 may be December 31 or may be integrated during August. From the above, it is difficult to create an integrated equipment database because there is no deadline for integrating change data. However, in this embodiment, since the change data is integrated in time series, the equipment database can be integrated in order to rearrange the equipment database in time series regardless of the integration date and time. Can be switched all at once.

(2) The database integration unit 40 integrates change data based on input from an input device connected to the network. In the equipment database change / test, if the test is not completed in time for the operation start date, there may be a problem with the change. Rather than integrating the change data while testing the equipment database, the change data is integrated based on the input from the maintenance console D, so that the operator changes the operation start date itself when a malfunction occurs. Is possible.

(3) Conventionally, for example, when the power system equipment shared by the operation bases 2A and 2B is changed, both the operation bases 2A and 2B have to change and test their respective equipment databases. However, when the equipment database is integrated as in the present embodiment, one of them only needs to change and test the equipment database, so the load of the equipment database change work shared by the operation bases is reduced. Reduced.

However, as illustrated in FIG. 10, the facility DB changing unit 22 includes an operation base extracting unit 22a. The operation site extraction unit 22a is a processing unit that searches and extracts the facility database of the operation site designated by the operator from the facility database read from the active facility DB storage unit 21 or the integrated facility DB storage unit 43. . The extracted equipment database is output to the maintenance table D.

  In the present embodiment having the above-described configuration, the following operational effects can be obtained in addition to the above-described embodiment. The equipment database of this embodiment is a database in which data related to power system equipment of a plurality of operation bases 2A to 2E is integrated. Therefore, the worker changes the equipment database based on the equipment database including all data related to the power system equipment of the plurality of operation bases 2A to 2E. In the present embodiment, since the operation base extraction unit 22a is provided, the operator can search and display an equipment database of a desired operation base. Therefore, the facility database change operation is simplified.

  In the present embodiment, for example, it is also possible to extract the equipment database of the operation base 2B in which the operation base 2A is another operation base. Therefore, for example, even when an abnormality occurs in the monitoring control console of the operation base 2B, the equipment database can be changed, tested, and integrated using the monitoring control console C and the maintenance console D of the operation base 2A. Become.

[Third embodiment]
The configuration of the power system monitoring and control system of the third embodiment is basically the same as that of the first embodiment. However, as shown in FIG. 11, the facility DB changing unit 22 includes an operation base changing unit 22b. The operation base changing unit 22b is a processing unit that changes the operation base that monitors and controls the power system facility based on the input from the maintenance console D.

  In the present embodiment having the above-described configuration, the following operational effects can be obtained in addition to the above-described embodiment. For example, as illustrated in FIG. 12, the operation base changing unit 22b reads the integrated equipment data stored in the integrated equipment DB storage unit 43, and selects the monitoring control operation base from the information about the equipment A from the operation base 2A. Change to 2B. In this embodiment, when a monitoring control server at a certain operating base fails, the monitoring control server at another operating base can perform monitoring control of the operating base where the monitoring control server has failed.
