Description

  The present invention relates to a system and method capable of efficiently updating facilities in a distributed monitoring control system that performs monitoring control of facilities arranged in a power system by the monitoring control system.

  2. Description of the Related Art Conventionally, in an electric power system of an electric power plant, monitoring control of facilities and the like is performed in a distributed manner by a monitoring control system such as a control station installed in each place. Each system is independent, and maintenance of data such as equipment is performed on a management screen of a monitoring control system in each control station or the like.

  However, equipment installed at the boundaries of the power system is monitored from multiple control stations, etc., and maintenance of the equipment data is required by the relevant monitoring and control systems for the renewal of the equipment. It becomes.

  In the past, a request for data update to a supervisory control system of another control center was made by a person in charge of maintenance of the supervisory control system in connection with the update work of the equipment controlled by the supervisory control system of a certain control center. There was a problem with accuracy.

For this reason, there has been proposed a technique for reflecting update of data on facilities and the like in the monitoring control system in a database connected to a network (for example, see Patent Document 1 and Patent Document 2).
JP 2003-032916 A JP 09-308138 A

  The monitoring and control of the electric power system in the electric power company's power plant, substation, etc. is generally performed in a monitoring / control system of a control station that controls a remote monitoring and control device (TC), a circuit breaker (CB), a disconnecting switch (LS), a line The state and measurement information of equipment such as ground (LE) are acquired from a remote monitoring control device (TC), and control information such as “ON” and “OFF” of the equipment is transmitted.

  Specifically, for equipment monitoring, the equipment information transmitted from the remote supervisory control device (TC) is displayed on the supervisory control screen of the supervisory control system based on the supervisory control data defined in the screen symbol. This is done by drawing. On the other hand, facility control is performed by transmitting an operation signal from the monitoring control screen of the monitoring control system to the corresponding remote monitoring control device (TC) based on the monitoring control data defined in the screen symbol ( FIG. 1).

  However, it is necessary for the monitoring target to capture the state of the equipment of the adjacent control station depending on the configuration of the power system, and in addition to the equipment managed by the local station, attribute data of the equipment controlled by the other control station is also required.

  In the conventional method, when there is equipment renewal work at the boundary of the power system, etc., it is necessary to maintain a monitoring control system such as all control stations that use the attribute data of the equipment. Expenses were incurred (Figure 2).

  FIG. 3 shows a business flow of the conventional method. The person in charge of the supervisory control system of the control station 2 whose own equipment has been updated (S301), there has been a work of requesting the source data to be updated to other related control stations for the updated equipment. (S302). In addition, the person in charge at the other control center or the like who has received the update request also needs to perform processing such as update of source data (S303), conversion to object data (S304), confirmation test, etc. (S305). It was a big burden.

  The present invention has been made in view of such circumstances. By installing a single equipment attribute database in a distributed monitoring and control system, maintenance of updated equipment attribute data can be collectively managed. , Decentralized monitoring and control system that updates the monitoring control data in the monitoring and control systems of all control stations, etc., and can update the data safely and reliably, while reducing costs and reducing the burden on workers It is another object of the present invention to provide a method for updating monitoring control data of other systems.

  The distributed monitoring and control system according to the present invention is a distributed monitoring and control system in which the control stations of the monitoring and control system arranged in a distributed manner in the power system perform the monitoring and control of the respective facilities. The facility attribute input means for storing the attribute data of the facility to be managed in the single facility attribute database in association with the information of the control station for which the facility is to be monitored and controlled, and for monitoring the monitoring control system of the control station In the input area to be displayed, change data input means for inputting change data, which is attribute change information generated in the equipment controlled by the control center, and the equipment attribute database holds based on the input change data Equipment attribute update means for updating the equipment attribute data of the equipment, and use destination information that is data of a control station that is subject to monitoring control of the equipment for which the equipment attribute data has been updated. And a monitoring control data updating unit for updating monitoring control data for performing monitoring control of the equipment for the monitoring control system of the control center detected as the usage information. It is characterized by providing.

  Here, “equipment” is not limited to facilities such as transformers, buses, and power transmission lines, but also includes transmission systems such as words and bits, switches, devices such as 43SW, facilities such as electric stations and offices. The “attribute” is information indicating the performance and function of the facility held by the power plant, substation, etc., and does not mean information regarding the operation status of the facility.

  The “single facility attribute database” can be held in an independent computer server connected via a network, or can be held in a server device of a monitoring control system such as one of control stations.

  Further, in the distributed monitoring and control system of the present invention, the use destination information is information based on screen definition information that defines screen symbols of equipment displayed on the monitoring control screen of the monitoring control system in each control station. The screen definition information input means for acquiring the screen definition information from the monitoring control system in each control station is provided.

  In other words, the monitoring control system such as each control station holds monitoring control data such as equipment attribute data in order to perform monitoring control, but defines the relationship between the screen symbol indicating equipment and the monitoring control data on the monitoring control screen. Therefore, the screen definition information is retained.

  Since the screen symbols include equipment other than the equipment that the local office has jurisdiction over, the usage information for each equipment is subject to monitoring control by acquiring screen definition information in the monitoring control system such as each control station. Can be detected.

  Further, in the distributed monitoring control system of the present invention, the monitoring control data update means receives the update of the facility attribute data in the facility attribute database and detects the control station monitoring control system detected as the use destination information. And generating and transmitting a data update file for updating monitoring control data for performing monitoring control of the equipment, in the monitoring control system of the control station that has received the transmission of the data updating file, A data update file executing means for automatically updating the monitoring control data for the monitoring control is provided.

  In other words, as a method for updating the monitoring control data in the monitoring control system of the control station, the equipment attribute data in the equipment attribute database is updated, a data update file is generated based on the updated equipment attribute data, and the usage destination This is done by transmitting to the supervisory control system of the control station detected by the information.

  Thereby, the monitoring control data in the monitoring control system of the control station can be updated quickly.

  The data update file can also be processed more quickly by using, for example, a self-executable file format.

  The data update file in the distributed monitoring control system of the present invention can be updated by a system other than the monitoring control system at the control station.

  That is, by individually defining the data update file generation method, it is possible to cope with a control relay station other than the control station.

  Furthermore, the distributed monitoring and control system of the present invention further includes a confirmation test alternative means for substituting a confirmation test at the control station detected as the use destination information for the equipment attribute data updated by the equipment attribute update means. The update of the data in the equipment attribute database is confirmed based on the result of the confirmation test.

  As a result, it is possible to omit a confirmation test performed at each control station or the like, and there are advantages in terms of cost and period.

  The confirmation test can be executed in a monitoring control system of a control station that has jurisdiction over the updated equipment, a maintenance server, or the like.

  Further, the data updating method in the distributed monitoring and control system of the present invention integrates the attribute data of facilities managed by each control station into a single facility attribute database, The attribute data of the equipment is updated in the equipment attribute database based on the change input of the attribute data of the equipment, and the equipment is subject to monitoring control based on the update contents of the attribute data of the equipment in the equipment attribute database. In the supervisory control system of the control station, the supervisory control data necessary for supervisory control is updated.

  According to the distributed monitoring and control system of the present invention and the method for updating equipment data in the distributed monitoring and control system, only the control center that updated the equipment needs to update the data of the equipment attribute, and the confirmation at the other control stations Since testing can be omitted, maintenance costs can be reduced.

  In addition, it is possible to switch to the latest data at the same time in the monitoring control system at a plurality of control stations.

  Furthermore, the data update operation can be unified at the control station having jurisdiction over the facilities, and the reliability of the data can be improved.

  Further, the person in charge at the other control station that has received the data update request has been required to perform operations such as maintenance of the source data on the management screen of the monitoring control system in the same manner as the person in charge at the control center 2.

  On the other hand, in the distributed monitoring control system according to the present embodiment of FIG. 5, the source data related to the attributes of the facilities held by the monitoring control systems of the respective control stations are integrated into a single DB (equipment attribute database). The above-described maintenance server 2 performs management.

  Thereby, the person in charge of the control center 2 performs maintenance of the source data related to the attribute of the facility that needs to be updated with respect to the data held in the single facility attribute database. In response to the update of the equipment attribute data in the equipment attribute database, the corresponding location that has been updated is automatically reflected in the monitoring control system such as another control station that is subject to the monitoring control of the equipment.

  In FIGS. 2 and 5, the source data and the object data are expressed as different databases. However, this is for convenience of explanation, and when updating the data in FIG. Transformation can also be viewed as a series of tasks. Therefore, it can be considered that only the source data of the equipment attributes is separated from the monitoring control system database in each control station and integrated into a single database.

  In FIG. 6, the business flow of the distributed monitoring control system 1 of this embodiment will be described in comparison with FIG. 3 showing the conventional method.

  As described above, in the conventional method shown in FIG. 3, the source data is maintained at other control stations in response to the update of the facilities under the control of the control station 2, and each control station conducts a confirmation test. It was.

  The central processing units 42 and 52 of the supervisory control system (4) of the control station 1 and the supervisory control system (5) of the control station 2 are provided with a supervisory control system, and are applicable when the equipment in charge is updated. Change data input means 421 and 521 for inputting equipment change data, confirmation test alternative means 422 and 522 for determining the appropriateness of the updated equipment attribute data, and the data update file received automatically. Are provided with data update file execution means 423 and 523 to be executed.

  The storage units 43 and 53 hold monitoring control data that is data such as attributes of equipment to be monitored and controlled.

The monitors of the output units 45 and 55 are provided with two types of operation screens: a monitoring control screen for performing monitoring control of connected equipment and a management screen for managing the monitoring control system.
On the monitoring control screen, screen symbols indicating equipment connected to the power system are displayed, and the status of the equipment is displayed by screen symbols based on the equipment attributes of the monitoring control data held by the storage units 43 and 53.

  Further, screen definition information that defines a link relationship between the screen symbol of the equipment displayed on the monitoring control screen and the monitoring control data of the corresponding equipment is stored in the storage units 43 and 53.

  FIG. 8 shows a configuration example of the screen definition information. The monitoring control screen (FIG. 1) displays facility information transmitted from the remote monitoring control device (TC) 1 (46) or the like based on facility attribute data. In the example of the screen definition information shown in FIG. 8, the link between the element number of the symbol displayed on the monitoring control screen such as 101, 102 and the name of the equipment (identification information) provided in the equipment attribute DB 231 (FIG. 9) described later. The data of the control center that has jurisdiction over the equipment is also retained.

  Note that the display on the monitoring control screen in this example is performed based on data indicating connection states of nodes and branches constituting the power system held by the monitoring control system of the control center.

  In other words, according to the screen definition information, the symbol (node) of the facility at the site is displayed on the screen, and the symbol of the facility at another location connected by the symbol and the transmission / distribution line (branch) is also displayed on the screen. Information on the status of equipment at other locations is obtained from other locations through communication lines or telephone contact and reflected on the screen.

  The maintenance server 2 includes a transmission / reception unit 21 connected to the communication network 3, a central processing unit 22 that performs arithmetic processing related to maintenance of a monitoring control system such as a control station, a storage unit 23 that holds data such as control station equipment, It comprises an input unit 24 such as a keyboard for inputting data, and an output unit 25 such as a display device or a printer for outputting data.

  In FIG. 7, the transmission / reception unit 21 of the maintenance server 2 is connected via a communication network 3 to the monitoring control system (4) of the control station 1, the monitoring control system (5) of the control station 2, and the like.

  The storage unit 23 includes a facility attribute DB 231 that stores information on the attributes of the facilities that the control station 1, the control station 2, and the like have, and a control station that stores information on the facilities that the control station 1, the control station 2, and the like perform monitoring control. It is comprised by DB232 etc.

  The central processing unit 22 is responsible for the transmission / reception processing unit 221 that exchanges data with the transmission / reception unit 21 and the input / output processing unit 222 that exchanges data with the input unit 24 or the output unit 25. Equipment attribute input means 223 for inputting equipment attribute data, screen definition information input means 224 for inputting data of equipment to be monitored and controlled by each control center, and updating the database based on the change data of the equipment attributes in charge Equipment attribute updating means 225 for performing monitoring control on equipment whose equipment attribute data has been updated, use destination information detecting means 226 for detecting data of other control stations, and monitoring and controlling equipment for which equipment attribute data has been updated Monitoring control data updating means 227 for updating the monitoring control data of the monitoring control system in another control station to be the target.

Next, a configuration example of the database held by the storage unit 23 will be described.
The facility attribute DB 231 shown in FIG. 9 stores attribute data of facilities managed by control stations such as the control station 1 and the control station 2.

  The information regarding the attribute of the equipment is information that should be held by each control station having jurisdiction over the equipment, but in the present embodiment, the information is held in the storage unit 23 of the maintenance server 2 as a single equipment attribute database.

  Specifically, in association with the identification information of each facility, the identification information of the control station that has jurisdiction over the facility, the attribute information of the facility, that is, the type of facility such as a switch / disconnector, It holds information such as the performance of facilities such as switching capability, power supply number, cut-off current, etc., and various flags related to functions such as alarm output, color change range, interlock target, and restoration procedure.

  In the control station DB 232 shown in FIG. 10, data on facilities and the like which are controlled by the control stations such as the control station 1 and the control station 2 are stored.

  Here, the equipment that each control station is subject to monitoring control is not limited to the equipment that the control station has jurisdiction of, but includes equipment that other control stations or the like have jurisdiction over. This is because the object of monitoring control in the control station needs to capture the state of the facilities that the adjacent control station has jurisdiction depending on the power system configuration.

  Specifically, the supervisory control screens of the supervisory control systems of the respective control stations display the power system diagram and the screen symbols of the equipment connected to the grids, but the supervisory control system displays those supervisory control screens. Therefore, the screen definition information that defines the screen symbol of equipment is held.

  The maintenance server 2 acquires the screen definition information from the monitoring control system of each control station, and holds it in the screen definition information table. Furthermore, the information on the control center to be monitored and controlled is managed in units of individual facilities by using the use destination information table in which the screen definition information is totaled for each facility.

  Next, a flow from construction to operation of the database in the distributed monitoring control system 1 of this embodiment will be described with reference to FIG.

  First, in the conventional system, the source data related to the equipment attribute is separated from the data of the equipment managed by the monitoring control system of each control center (S101). The separated facility attribute data is transmitted to the maintenance server 2 (S102).

  The maintenance server 2 integrates the facility attribute data transmitted from each control station, and constructs a single facility attribute database in all the control stations (S103).

  The maintenance server 2 holds all source data in the system, and the maintenance of the data is performed at the control office and the maintenance company terminal 14 that have jurisdiction over them.

  Further, the maintenance server 2 creates screen symbol data, and acquires and inputs screen definition information for defining equipment to be monitored and controlled from the monitoring control system of each control station (S104: screen definition information). Input means 224).

  As a result, it is possible to know the equipment to be monitored and controlled by the monitoring control system of the control station. In other words, the equipment attribute data is limited to the equipment that has jurisdiction, but in the screen definition information, equipment and the like adjacent to each other in the power system are also subject to monitoring control, so that information can be acquired.

  Since the acquired screen definition information is acquired in units of control stations, these data are totaled for each facility (S105). Thereby, it is possible to grasp at which control station the individual equipment is the target of the monitoring control.

  In FIG. 10, the control stations that have jurisdiction over the facilities are shown as double circles, but the control stations that are not supervised but are subject to supervisory control are shown as single circles. Here, the information about the single circle control station can be detected as the use destination information (S106).

  In the equipment attribute DB 231, the equipment attributes are managed for each equipment name. However, in the use destination information table of the control center DB 232, the equipment attributes are managed for each equipment name, and these data are associated and stored (S 107 · equipment attribute input). Means 223).

  The associated control station of the use destination requires equipment attribute data of the equipment that performs the monitoring control in the monitoring control system. Therefore, the equipment attribute data of the equipment corresponding to the control station of the use destination is transmitted (S108).

  Accordingly, the monitoring control system of the control station that has received the transmission of the equipment attribute data outputs the state of the screen symbol of the equipment based on the equipment attribute data (S109), and based on the state of the screen symbol of the equipment, An operation signal is transmitted to the supervisory controller (TC) (S110).

  In addition, by including data such as the name of the control station that has jurisdiction over the equipment attribute data transmitted here, the monitoring control system of the control station that has received the equipment attribute data is not supervised. For the equipment to be controlled, it is possible to know information such as a control station that performs supervisory control and a remote supervisory control device (TC).

  As a result, in the supervisory control system of the control station that has received the transmission of the equipment attribute data, there is a case where, for example, there is a change in the supervising control facility for the equipment to be monitored and controlled, although it is not in charge. In addition, it is possible to acquire accurate monitoring control data based on the acquired data of the control station and the remote monitoring control device (TC).

Next, after the construction of the distributed monitoring control system 1 of the present embodiment, the flow when the equipment is updated will be described with reference to FIG.
In the example of FIG. 12, the attribute has changed due to the construction of the equipment 21 (57) managed by the control center 2 (S201).

  The change data input means 521 of the monitoring control system (5) of the control station 2 displays the change data input area of the equipment 21 (57) whose attribute has changed on the management screen and inputs the change contents of the equipment. (S202). The input change data is transmitted to the maintenance server 2 via the communication network 3 (S203).

  The equipment attribute update unit 225 of the maintenance server 2 that has received the transmission updates (unconfirmed) the equipment attribute data of the equipment 21 (57) held in the equipment attribute DB 231 provided in the storage unit 23 (S204). The updated equipment attribute data of the equipment 21 (57) is accessible from the monitoring control system (5) of the control center 2 and can be displayed on the management screen (S205).

  The person in charge of the monitoring control system (5) of the control center 2 converts the updated equipment attribute data of the equipment 21 (57) from the source data to the object data (S206). After that, the confirmation test alternative means 422 performs a confirmation test such as a defect check by operation confirmation on the converted object data (S207).

  That is, the facility attribute data in the facility attribute DB 231 is source data that can be easily updated in the monitoring control system such as each control station, and the monitoring control data update in the monitoring control system of other control stations conforms to the system. Executed after converting the converted object data.

  If it is determined by the confirmation test that the object data is appropriate, the result of the confirmation test is transmitted to the maintenance server 2 (S208). In response to the result that the object data is appropriate, the facility attribute update unit 225 determines to update the facility attribute data of the facility 21 (57) held in the facility attribute DB 231. Thereafter, the equipment attribute data is transmitted to a monitoring control system such as another control station, but the confirmation test is not performed (S209 / confirmation test alternative means 422).

  In the present embodiment, the update of the equipment attribute data is managed by the equipment attribute DB 231 (FIG. 13). Specifically, when change data is input from the supervisory control system (5) of the control station 2 that has jurisdiction over the equipment 21 (57), the equipment attribute data is updated based on the change data. Sets the provisional registration flag to “present”. Thereafter, a person in charge of the monitoring control system (5) of the control station 2 performs a confirmation test based on the updated equipment attribute data, and transmits the result to the maintenance server 2. If the result is appropriate, the maintenance server 2 confirms the update and sets the temporary registration flag to “none”. As a result, the monitoring control data update unit 227, which will be described later, determines the update of the equipment attribute data, that is, creates a data update file by detecting a change in the status of the temporary registration flag from “present” to “none”. Start.

  The use destination information detection means 226 of the maintenance server 2 receives the confirmation of the update of the equipment attribute data and detects the control station 1 or the like as the use destination information of the equipment 21 (57) (S210). Next, the supervisory control data update unit 227 creates a data update file (source data) for the supervisory control system (4) of the detected use-use control center 1 (S211). The created data update file is transmitted to the monitoring control system (4) of the control station 1 (S212).

  In the monitoring control system (4) of the control station 1 which is the use destination that has received the data update file, the data update file execution means 423 converts the data update file in a self-executable file format into object data. (S213), the object data is switched (S214).

  In the present embodiment, the equipment for which the update of the equipment attribute data is confirmed is managed in the use destination information table of the control center DB 232 until transmission of the data update file to the use control station (FIG. 14).

  Specifically, in the use destination information table, information on a control station that has jurisdiction over the equipment and a control station that is the target of monitoring control is stored in units of equipment. In FIG. 14, the control stations that are in charge are indicated by double circles, and the control stations that are subject to monitoring control are indicated by single circles. That is, the facility 21 (57) whose facility attribute data has been updated is a facility that is controlled by the control station 2, and the control station 1, the control relay station 1, and the like perform monitoring control.

  The use destination information detection unit 226 detects a control station indicated by a single circle, and the monitoring control data update unit 227 generates a data conversion file according to the system type of the control station and transmits it to a predetermined IP address.

  As described above, according to the distributed monitoring and control system of the present invention, in addition to the effect of reducing the cost and the burden of work, the data update work is performed at the control station having jurisdiction over the equipment. Can be ensured.

  Furthermore, since all processes can be performed safely, reliably and quickly, it has a significant effect on the point that it is possible to provide a more stable service for the electric utility that supplies power, which is the infrastructure of daily life. I can expect.
