The purpose of this project is to provide technology for performing maintenance.

C1 Conventional technology In recent years, electric power systems have become increasingly large and complex, and their management and operation must become more sophisticated.At the same time, with the advancement of the information society, supply reliability has also become increasingly required. As a result, comprehensive automation of equipment is being promoted to ensure efficient operation of power distribution systems.

FIG. 2 is a configuration diagram showing an example of a power distribution system control device for power equipment. In the figure, all of the systems are duplicated, so if one computer malfunctions or the equipment needs to be inspected, the other computer provides backup and continues operation. The data collection and distribution device 21 has two systems of control devices 22a and 22b.
each high-speed data interface (not shown)
The control devices 22a and 22b are connected to the display devices 23a and 23b of the system via respective cooperation interfaces (not shown). Control device 22
a and 22b are connected by a computer link (not shown), and display devices 23a and 23b are connected by a data link (not shown).

Output to a kanji printer, hard copy device, floppy disk, etc.

This power distribution system control device has the following functions.

(1) Monitoring of distribution lines, (2) Automatic control of distribution equipment and distribution line switches, (3) Automatic processing of management and operation tasks, (4) Data maintenance, (5) Simulation, (6) System operation, Of the above, data maintenance involves making changes to distribution line diagrams, equipment data, etc. in advance due to scheduled construction work.
After registration, the operational data can be changed on the day by simply specifying it. In the configuration shown in FIG. 2, a graphic CRT and a character CRTI are used.

In general, maintenance work for power distribution system control equipment for power equipment involves registering maintenance subjects, and pre-registering data related to new construction, removal, and modification of power distribution equipment for each subject in the control equipment in the form of provisional or scheduled registration. It is important to be aware of this.

The maintenance data becomes actual operational data by registering it after the completion of the construction work. The control device shown in FIG. 2 also includes an execution area in which the power distribution equipment data currently in operation (actual operation data) exists, and a scheduled area in which maintenance data scheduled for the execution area exists. However, since a graphic CRT for displaying diagrams such as system diagrams can display only one of the areas, switching between the execution area and the scheduled area is performed by file operations.

The table below shows the stages of subject processing.

Table 1: Here, what is the maintenance subject? This is a subject to manage maintenance work on a construction-by-construction basis.For example, in the control device mentioned above, up to 200 items can be registered, and 1 item per item.
It is possible to set up to 0 related subjects. Only subjects in the schedule registration state that can be expanded to the schedule area can be related subjects.

FIG. 3 is a flowchart showing an example of general maintenance work. In the figure, main maintenance operations with a single subject are performed in the following order: ■Maintenance start, ■Equipment data maintenance and system diagram maintenance, ■System data creation, ■Own station test, ■Confirmation, and ■Maintenance end.

The general relationship between operator operations and data processing is as follows.

■Maintenance start First, copy the execution area data to the schedule area, and if there is a subject related to the subject, expand the maintenance data to the schedule area.

■System diagram maintenance and equipment data maintenance If there is maintenance data for the subject, expand that data on the scheduled area. Here, what is pedigree chart maintenance?
Maintenance involves inputting data such as the shape, position, name, and position of distribution equipment while displaying the distribution equipment on a system diagram. Equipment data maintenance is the process of inputting data such as the distribution equipment's shape, position, name, and location, etc., while displaying the distribution equipment on a system diagram. This refers to maintenance that involves inputting detailed data. During system diagram maintenance, the system diagram of the distribution line that is subject to maintenance is displayed on the graphic CRT shown in Figure 2, and maintenance data is also input from the graphic CRT and developed on the graphic CRT, as well as a data file. (hereinafter, this data will be referred to as system diagram maintenance data). For equipment data maintenance, the system diagram of the distribution line that is subject to maintenance is displayed on the graphic CRT shown in Figure 2.
However, the maintenance data is displayed in character CR.
Input from TI and written to data file. still,
When inputting data, the data is usually entered in the order of system diagram maintenance and equipment data maintenance, but either can be entered first, or only one may be entered.

■ Genealogical data creation Check and develop maintenance data.

■ Own station test Check maintenance data on graphic CRT.

■Confirmation This operation is required only when registering this subject as a schedule.

■Maintenance completed Copy execution area data to the scheduled area.

In the flow shown in Figure 3, ■ After the maintenance is completed, the state will be the same as before the maintenance started, and any subsequent operations can be performed at the specified timing, and ■ After the work is completed, the state will be the same as before the maintenance started. Then, any subsequent operations can be performed at a predetermined timing.

FIG. 4 is a configuration diagram showing an example of maintenance business development. In the figure, 41 is first maintenance data, 42 is second maintenance data, 43 is execution area data,
Assuming that the new installation of the first maintenance data 41 is subject A, the new installation of the second maintenance data 42 is subject B, and the order of construction is subject A - subject B, subject A is first registered as a schedule, and then subject A is related. When performing maintenance with subject B as the subject, the system diagram of the scheduled area is the execution area data 43
The first maintenance data 41 is expanded. Furthermore, if the subject to be constructed next to Subject A and Subject B is C, and after subject B is scheduled and maintenance is performed on subject C with subject A and subject B as related subjects, the system diagram of the scheduled area is the execution area. The first maintenance data 41 and the second maintenance data 42 are expanded to the data 43 (e). Figures (-L), (b), (d), (e)
Each figure is a systematic diagram of the planned area in each phase.

The development of the maintenance work shown in FIG. 4 is explained below using this example.

In other words, when maintenance starts, first, Figure (2L)
Copy the execution area data 43 to the scheduled area as shown in
If there is a subject A related to the subject name, the maintenance data 41 is developed in the scheduled area as shown in FIG. 3(b). Furthermore, if the maintenance data 42' for related subject B has already been created up to the stage shown in Figure (C), this data 42' is applied to the scheduled area to complete the configuration as shown in Figure (d). . Subject B maintenance data 42
' has not been created, the system data 42 of subject B is created as required and developed in the scheduled area as shown in FIG. 3(e). At the end of maintenance, the data in the scheduled area is returned to the execution area data state shown in FIG.

D0 Problems to be Solved by the Invention In the above-described maintenance method for a power distribution system control device, when creating system data, system diagram maintenance data is developed on a graphic CRT. Therefore, if the system diagram maintenance data is applied to the graphic CRT before creating the system data, the system diagram maintenance data will be duplicated when the system data is created, making it impossible to expand. Therefore, at the end of system diagram maintenance, a process is always performed to return the data developed on the graphic CRT to the state before system diagram maintenance.

This is because when performing both system diagram maintenance and equipment data maintenance, the consistency of the data input from both sides is checked and then combined to create maintenance data that can be scheduled and registered. If necessary, the data created by system diagram maintenance alone will not be maintenance data that can be registered as scheduled, and on the other hand, when creating system data, the graphic CRT must be in a state where maintenance data that can be registered as planned can be expanded. This will return the graphic CRT to the state it was in before the system diagram maintenance.

Because of this process, when performing equipment data maintenance after performing system diagram maintenance, the system diagram before the system diagram maintenance is displayed on the graphic CRT, the system diagram maintenance data is not applied, and the equipment data is maintained while referring to the system diagram. Data maintenance cannot be performed. As a result, the consistency between the system diagram and the equipment data is lost, making it difficult to quickly maintain the equipment data, and input errors due to misunderstandings also occur.

The present invention was developed in view of these problems, and
The present invention aims to provide a maintenance method for a power distribution system control device that performs maintenance of equipment data while referring to a system diagram, and performs maintenance of equipment data quickly and accurately without compromising consistency between the two.

88 Means for Solving the Problems The means for solving the above problems in the present invention are to input new system chart maintenance data from the system diagram displayed on the graphic CRT, and to input more detailed attribute data.

A deletion flag is set when deleting system diagram maintenance data developed in Load the editing data of the subject including the diagram maintenance data and display it on the graphic CRT.
The maintenance method will be developed over time.

11 Effects The present invention improves the maintenance work-related functions of the general power distribution system control device shown in FIG. 2. System diagram maintenance includes system diagram display, maintenance data input, All development is graphic CRT
However, in equipment data maintenance, the system diagram is displayed on a graphic CRT, and maintenance data is entered on a character CRT. This is an improvement over the fact that it was impractical to transfer data to a graphic CRT due to strict independence requirements.

In the present invention, a predetermined flag setting means is provided, and this erasure flag is set when erasing the system diagram maintenance data developed on the graphic CRT. On the other hand, before starting system diagram maintenance or facility data maintenance, the state of the deletion flag is always checked, and if the deletion flag is set, the maintenance data of the subject is read. The editing data includes the latest system diagram maintenance data, and the system diagram maintenance data is developed on the system diagram displayed on the graphic CRT, and system diagram maintenance or equipment data maintenance is performed while monitoring the system diagram.

Note that even when the system diagram maintenance is completed, the system diagram maintenance data is not immediately deleted as in the conventional method, but is deleted as required, for example, when creating system data.
