Field of the Invention The present invention relates to a power system supervisory control device capable of performing addition / change / deletion work (hereinafter simply referred to as “change”) of a power system facility database and a data maintenance method for this device.

[0002]

2. Description of the Related Art FIG. 11 shows a flow of work for changing a facility database of a conventional power system monitoring and controlling apparatus. The conventional modification work is as follows. In FIG. 11, a change to the equipment database source 105 is input by a human system, and after the change,
The expansion processing 106 in the computer generates the equipment database object 107.

In this case, the equipment database source 105
It is difficult to make only the changed parts of the object partly. Therefore, the equipment database source 105
Equipment database source 1 regardless of the amount of change
05 Expand the whole equipment database object 10
7 would have to be regenerated and would always consume a lot of time.

Further, in a large-scale facility change and a facility change when some jobs are congested, a plurality of people can change the same facility database source at the same time. May be overwritten with the content changed by another person, and may be in the state before the change.

In the case of a small-scale equipment change, the equipment database object 107 is directly changed in order to reduce the change work time, but it is necessary to surely reflect the change contents in the source to maintain the consistency. Further, these facility changing works must be carried out at the time when the actual electric power system is changed, so that workers must be assigned each time.

[0006]

As described above, the conventional electric power system monitoring and controlling apparatus has the following problems listed in to. It takes a lot of time regardless of the changes made to the equipment database objects.
