Description

  The present invention relates to a power system monitoring control system in which a monitoring control facility for monitoring and controlling a power system is provided for each control station.

  For example, the monitoring and control equipment captures the state of each power equipment such as a circuit breaker and a switch, and the current value and voltage value of each equipment into a control station monitoring and control device (computer system) via a remote monitoring and control device. Each facility is controlled by the control station monitoring control device via the remote monitoring control device. A system diagram screen is displayed on the display of the control station monitoring and control device, and a screen in which symbols of each facility are arranged on the system diagram is displayed based on position information of each facility. Moreover, the control center monitoring control apparatus has a function of creating an operation slip indicating an operation procedure for changing the power system configuration under a predetermined condition (for example, see Patent Document 1). Based on the created operation slip, each facility is remotely operated with the support of the control center monitoring and control device.

  Such supervisory control equipment is arranged for each control station, and each supervisory control equipment functions independently. In other words, a power system that has jurisdiction and jurisdiction is determined for each control station, and a monitoring control facility is provided for each power system. In each monitoring and control facility, a code (equipment code) for identifying each facility is defined and stored in a database, and an operation slip is created using the facility code.

JP 2010-273516 A

  By the way, when operating the power equipment between a plurality of control stations, an operation slip is created by the monitoring control equipment of each control station. At this time, in order to confirm the operation procedure of the adjacent and linked control stations, operation sheets including the operation procedures of the adjacent control stations are created at both control stations. For this reason, some operation procedures had to be created twice, which required a great deal of labor and time.

  Also, since there is no function to electronically send operation slips created at the control station to other control stations, the operation slip is only sent to the adjacent control station by FAX, and is sent at the received control station. The operation slip / operation procedure cannot be used, and only the operation procedure is confirmed. Furthermore, even if it has a function to send operation slips electronically, equipment codes are defined and stored for each control station / monitoring control facility, so use / quote operation slips created at other control stations. I couldn't.

  Therefore, an object of the present invention is to provide a power system monitoring and control system capable of easily creating operation slips and the like over a plurality of control stations.

In order to solve the above-mentioned problem, the invention according to claim 1 is a power system monitoring control system in which a monitoring control facility for monitoring and controlling a power system is provided for each control station. An equipment attribute storage means that can read the control equipment and stores the attributes of each equipment of the power system, and an operation slip indicating an operation procedure of each equipment based on an instruction input to each monitoring control equipment. An operation slip creating means for creating, and an operation slip transmitting means for transmitting the operation slip created by the operation slip creating means to other monitoring and control equipment, wherein the operation slip creating means is the equipment attribute storage means. The operation slip received from other monitoring and control equipment can be edited based on the attribute stored in the operation slip, and the operation slip transmission means is pre-stored with the operation slip created by the operation slip creation means. Each monitoring and control facility Based on the power system area for monitoring control, determine the other monitoring control facility to transmit an operation form, characterized in that.

  According to the present invention, for example, in the monitoring control facility A of a certain control station, the operation slip is created by the operation slip creating means, and the operation slip is transmitted to the monitoring control equipment B of another control station by the operation slip transmitting means. Suppose that In this case, in another monitoring control facility B, it is possible to create an operation slip for the own control station by the operation slip creating means while editing the operation slip received from the monitoring control facility A. At this time, based on the data / information in the equipment attribute storage means that can be read by both of the monitoring control equipment A and B, that is, the attribute (equipment code) of each equipment unified, the operation slip from the monitoring control equipment A is edited. -To quote, the operation slip created by the monitoring control facility A can be used as it is.

Also , when the operation slip is created by the operation slip creation means, the related and linked monitoring and control equipment to which the operation slip is to be transmitted is determined based on the operation slip and the power system area of each monitoring and control facility. . That is, a monitoring control facility other than its own control station that monitors and controls the power system area of the facility included in the created operation slip is determined, and the operation slip is transmitted to the determined monitoring control facility.

  According to the first aspect of the present invention, it is possible to create an operation slip with its own monitoring control equipment while editing an operation slip created with another monitoring control equipment. Etc. can be easily created. In other words, it is not necessary to create operation slips that overlap each other between adjacent control stations, and equivalent and similar operation slips created by other control stations can be diverted. And time can be significantly reduced, and the creation of operation slips is highly efficient. In addition, there is no need to create duplicate operation slips, operation slips created by other control stations can be edited and quoted, and operation slips can be created and edited based on the centralized attributes of each facility. It is possible to prevent or reduce creation mistakes such as mistaken operation target equipment.

In addition , when an operation slip is created at its own control station, the monitoring / control equipment of the related / linked control station to which the operation slip is to be sent is automatically determined and the operation slip is transmitted. The operation slip can be transmitted reliably and without omission to the control station. As a result, it is possible to promote confirmation and use of operation slips for related / linked control stations.

This supervisory control system 1 is a system in which supervisory control equipment 5 for monitoring and controlling the power system / power equipment is arranged for each of the control stations C1 to Cn, and each supervisory control equipment 5 is mutually connected via the communication network NW. The integrated server (maintenance server) 2 and each monitoring control facility 5 are communicably connected to each other. Here, a power system area that has jurisdiction and jurisdiction is determined in advance for each of the control stations C1 to Cn, and a monitoring control facility 5 is provided for each power system area.

  The integrated server 2 is a server that manages and stores equipment attribute data of all equipment in the entire power system, and includes a data management unit 21 that manages equipment attribute data, and an integrated database (equipment attribute storage means) that stores equipment attribute data. 22. Then, as will be described later, the equipment attribute data transmitted from each monitoring control equipment 5 is integrated to construct a single integrated database 22 in all the control stations C1 to Cn. The attribute data is transmitted to the associated monitoring / control equipment 5. In this way, all the monitoring and control equipment 5 can read and use the unified equipment attribute data.

  Here, in the equipment attribute data / attribute of the equipment, the identification information of the control stations C1 to Cn having jurisdiction over the equipment corresponding to the element number / equipment code for identifying the equipment, the type of equipment, and the equipment are the switch. -In the case of a disconnector, it includes switching capacity, power supply number, performance / capacity such as breaking current, interlock target, recovery procedure, etc. Further, in this embodiment, the equipment attribute data in the integrated database 22 is transmitted to the related and linked monitoring control equipment 5, but each monitoring control equipment 5 directly accesses the integrated server 2 and the integrated database 22. Thus, the unified equipment attribute data may be read and used.

  Each monitoring control facility 5 includes a control center monitoring control device (monitoring control system) 3 and a remote monitoring control device 4, and the control center monitoring control device 3 and the remote monitoring control device 4 are connected to be able to communicate with each other. . The remote monitoring and control device 4 is connected to all the equipment to be monitored and controlled in a communicable manner, receives the state / status of each equipment, the current value and the voltage value passing through each equipment, etc., as control information. While transmitting to the monitoring control apparatus 3, based on the control command transmitted from the control center monitoring control apparatus 3, each facility is controlled and operated. Here, in FIG. 1, the remote monitoring control device 4 is illustrated below the control station monitoring control device 3, but each remote monitoring control device 4 can directly communicate via the communication network NW.

  The control center monitoring control device 3 stores monitoring information from the remote monitoring control device 4, or transmits control commands to the control center monitoring control device 3 as necessary to control and operate each facility. It is. Here, since the control station monitoring control devices 3 of the control stations C1 to Cn have the same configuration, the control station monitoring control device 3 of the first control station C1 will be mainly described below as an example (main body). .

  The control station monitoring and control device 3 mainly includes an input unit 31, a display unit 32, a communication unit 33, an equipment database 34, an operation form database 35, a support task (including an operation form transmission means) 36, and the like. And a central processing unit 37 for managing, controlling, and the like. Moreover, although not shown in figure, the monitoring information database which memorize | stores monitoring information is provided.

  The input unit 31 is an input device for inputting facility attribute change data and instruction information for the support task 36, which will be described later, and the display unit 32 is a display device for displaying monitoring information, a support screen by the support task 36, and the like. Yes, it consists of multiple monitors. The communication unit 33 communicates with the control station monitoring control device 3 and the integrated server 2 of the other control stations C2 to Cn via the communication network NW, and communicates with the remote monitoring control device 4. It is.

  The equipment database 34 stores equipment attribute data used at the self-control station C1, and not only the equipment attribute data of the equipment controlled by the self-control station C1, but also other control stations C2 to Cn are controlled by the self-control station C1. However, the equipment attribute data of the equipment to be used is also stored. In addition, the equipment attribute data is updated according to equipment update / renewal, new establishment, replacement, and the like.

  Specifically, for example, in the first control station C1, when the change data of the equipment whose attribute has changed is input through the input unit 31, the equipment database 34 of the own control station C1 is changed and the change data is integrated. Sent to the server 2. Next, the data management unit 21 of the integrated server 2 changes the equipment attribute data of the corresponding equipment in the integrated database 22 based on the changed data, and changes the related / linked control station monitoring control device 3. Data is sent. In response to this, in the related / linked control center monitoring control device 3, the equipment attribute data of the corresponding equipment in the equipment database 34 is changed based on the changed data.

  Here, the related / linked control station monitoring control device 3 means the control station monitoring control device 3 (monitoring control facility 5) which has jurisdiction over the equipment or uses equipment attribute data. The integrated server 2 includes a table memory that stores identification information of the control stations C1 to Cn having jurisdiction over the facilities and identification information of the control stations C1 to Cn that operate and use the facilities. Then, by referring to this table, the change data is transmitted to the related / connected control station monitoring control device 3. Further, before changing the integrated database 22 and the equipment database 34, an operation check test based on the changed data is performed in the changed control stations C1 to Cn, and after the normal operation is confirmed, the integrated database 22 and the equipment database 34 are installed. Changes to the database 34 are confirmed.

  In this way, the unified equipment attribute data is stored in the equipment database 34 of each control station C1 to Cn, and the unified equipment attribute data 22 is read indirectly in each monitoring control equipment 5, It can be used. In addition, on the display unit 32 of each control station monitoring and control device 3, a screen in which symbols of each facility are arranged on the system diagram is displayed based on the position information of each facility, and each support task 36 described later also displays each screen. Equipment is symbolized. At this time, the facility is symbolized based on the element number of the facility, but the facility attribute data including the element number is unified and unified, and each control station monitoring control device 3 can be used. In FIG. 3, the symbols other than the facilities managed by the self-control stations C1 to Cn can be appropriately displayed as symbols.

  The operation slip database 35 is a database for storing operation slips created by an operation support registration task 361 described later, operation slips received from the monitoring control equipment 5 of other control stations C2 to Cn, and the like. In addition, the operation slip in the operation slip database 35 can be read by the operation support registration task 361 or the like as described later.

  The support task 36 is program software for monitoring and operating each facility, and is mainly created as an operation support registration task (operation sheet creating means) 361 for creating an operation sheet indicating an operation procedure of each facility. And an operation support execution task 362 for supporting remote operation of each facility based on the operation slip. That is, when the support task 36 is activated, a main menu as shown in FIG. 2 is displayed on the display unit 32, and the operation support registration task 361 and the operation support execution task 362 can be selected.

  The operation support registration task 361 is a program for creating an operation slip on the basis of instructions and information input by the input unit 31. The created operation slip is used to control other control stations C2 to Cn that are related / linked. A function of transmitting to the site monitoring control device 3 is provided. Furthermore, based on the equipment attribute data stored in the integrated database 22, that is, the equipment database 34, it has a function capable of editing / quoting operation slips received from the control station monitoring control devices 3 of other control stations C2 to Cn. .

  Specifically, when creating an operation slip for the self-control station C1, when “new creation” P1 of the operation support registration task 361 in the main menu is selected, an operation slip header screen as shown in FIG. 3 is displayed. Displayed on the display unit 32. Then, according to each item on the operation slip header screen, information is input by the input unit 31 to create a header portion / cover of the operation slip (step S1 in FIG. 8).

  Subsequently, when “Procedure” on a toolbar (not shown) in the operation form header screen is selected, an operation form procedure screen as shown in FIG. 4 is displayed on the display unit 32 (step S2). When an operation slip is created independently without quoting or referring to another operation slip (in the case of “N” in step S3), “Insert” on a toolbar (not shown) in the screen is selected, and the screen In accordance with each item therein, the operation procedure and operation slips are created by inputting the operation contents for each facility sequentially and in time series by the input unit 31 (step S4).

  On the other hand, when an operation form is created by quoting and referring to another operation form (“Y” in step S3), that is, when creating an operation form with the linkage function, “quotation” on the toolbar in the screen is displayed. When selected, a quote dialog as shown in FIG. 5 is displayed on the display unit 32 (step S5). Then, when “other operation slip” P2 in the dialog is selected, a list of subject names of operation slips created in the past is read from the operation slip database 35 and displayed on the display unit 32, and “standard operation slip” in the dialog is displayed. When P3 is selected, a list of standard / typical operation slip subject names registered in advance is read from the operation slip database 35 and displayed on the display unit 32. Furthermore, when “Receiving operation slip” P4 in the dialog is selected, a list of operation slip subjects received from the monitoring control equipment 5 of other control stations C2 to Cn is read from the operation slip database 35 and displayed on the display unit 32. Displayed (step S6). Here, each subject list is displayed on a monitor (adjacent monitor) different from the monitor displaying the operation slip procedure screen.

  Next, when the operation slip to be cited is selected from the subject list, the selected operation slip is read from the operation slip database 35 and displayed on the monitor (step S7). For example, when a specific operation slip is selected from a list of operation slip subjects (received operation slip subject name list) received from other control stations C2 to Cn, as shown in FIG. 6, the operation of the selected operation slip is performed. Display the procedure. In this way, the operation slip in the operation slip database 35 can be read.

  When one or a plurality of operation procedures to be cited or referred to are selected from the operation slip, the selected operation procedure is inserted / copied into the operation procedure item in the operation slip procedure screen (FIG. 4). (Step S8). For example, when the operation procedure in the range P5 in FIG. 6 is selected, the selected operation procedure is inserted into the operation slip being created.

  By repeating such original creation, input, and citation (repeating up to “Y” in step S9), a target operation slip is created, and the created operation slip is stored in the operation slip database 35 (step S10). )

  When the operation slip created in this way is transmitted to the monitoring / control equipment 5 that is related / linked, when the “auxiliary task 2” P6 in the main menu (FIG. 2) of the support task 36 is selected, FIG. As shown, a screen including a “transmission / reception operation slip” (reception operation slip management area) is displayed on the display unit 32. When “Transmission (linkage)” P7 of “Transmission / reception operation slip” is selected, the created operation slip is transmitted as an electronic data file to the monitoring / control equipment 5 associated / linked.

  Here, the related and linked monitoring control equipment 5 is determined based on the created operation slip and the power system area that is monitored and controlled by each of the control stations C1 to Cn (each monitoring control equipment 5) stored in advance. . That is, the power system area (supervised area) monitored and controlled by each of the control stations C1 to Cn is preset, stored, and in the operation procedure of the created operation slip, Whether there is a procedure for operating the facility is searched, and if it exists, the control stations C2 to Cn are determined.

  Further, the timing for transmitting the operation slip may be immediately after the operation slip is created by the operation support registration task 361, or can be sent anytime after the creation. That is, by selecting an operation slip to be transmitted from the operation slips stored in the operation slip database 35 and selecting the monitoring control equipment 5 of any control station C2 to Cn, the arbitrary operation slip is changed to any monitoring control equipment. 5 can be sent at any time. Furthermore, in the “transmission / reception operation slip” of FIG. 7, for example, by selecting “inquiry”, the operation slip received from the other control stations C2 to Cn can be inquired and referred to at any time.

  According to the monitoring control system 1 having such a configuration, the operation slip is created by the monitoring control facility 5 of the own control station C1 while quoting and editing the operation slip created by the monitoring control facility 5 of the other control stations C2 to Cn. Therefore, it is possible to easily create an operation sheet that covers a plurality of control stations C1 to Cn. That is, for example, when an equipment controlled by an adjacent control center C2 is also an operation target, conventionally, as shown in FIG. 9, in the control station monitoring control device 101 of the own control station C1, the own control station C1 and the adjacent control station Not only the operation sheet for C2 but also the control station monitoring and control device 102 of the adjacent control station C2 had to generate operation sheets for the own control station C2 and the adjacent control station C1. In addition, because the respective control stations C1 and C2 have their own databases 101a and 102a, the operation slips created at the other control stations C2 and C1 cannot be used / quoted.

  On the other hand, in the present system 1, as shown in FIG. 10, in the control station monitoring and control device 3 of the own control station C1, an operation sheet for the own control station C1 and the adjacent control station C2 is created, and the created operation sheet is created. Is transmitted to the control station monitoring control device 3 of the adjacent control station C2, the operation sheet can be created by quoting and using the received operation sheet at the adjacent control station C2. Thus, it is not necessary to create operation sheets and operation procedures that overlap each other between the adjacent control stations C1 and C2, and equivalent and similar operation sheets created by other control stations C2 to Cn are used. Since it is possible, the labor and time required for creating operation slips can be significantly reduced, and the operation slip creation work becomes highly efficient. Furthermore, there is no need to create duplicate operation sheets, and operation sheets created by other control stations C2 to Cn can be edited / quoted, and operation sheets can be created based on the unified equipment attribute data of each facility. Because it is created / edited, it is possible to prevent or reduce creation errors such as wrong equipment to be operated.

  In addition, when an operation slip is created at the self-control station C1, the monitoring control equipment 5 of the related / linked control stations C2 to Cn to which the operation slip is to be transmitted is automatically determined, and the operation slip is transmitted. Therefore, it is possible to transmit the operation slip reliably and without omission to the related / linked control stations C2 to Cn. Thereby, it becomes possible to promote the confirmation and use of the operation slip to the related / linked control stations C2 to Cn.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, in the above embodiment, the monitoring control facility 5 is composed of the separate control station monitoring control device 3 and the remote monitoring control device 4, but the control station monitoring control device 3, the remote monitoring control device 4, May be configured integrally. Further, although the operation slip is transmitted to the monitoring control facility 5 determined by the support task 36, the operation slip may be transmitted to an arbitrary monitoring control facility 5 based on an operator's judgment. Furthermore, although the support task 36 includes an operation slip transmission unit, the operation support registration task 361 may transmit the created operation slip to the related and linked monitoring control equipment 5. In addition, when “Send (Linkage)” P7 is selected, the operation slip is sent to the related / linked monitoring control equipment 5, but without waiting for the selection of “Send (Link)” P7, After the vote is created, it may be automatically transmitted to the related / linked monitoring / control equipment 5.
