Description

Distribution system management system and its method {Management System for Distribution System of Power and Method

The present invention relates to a distribution system management system and a method thereof, and more specifically, the high-voltage system of the distribution line computerized by the substation and the progress of the system represented by the system map and system map for the distribution distribution for the computerization and efficiency of the distribution command service It is about system management system and method.

Conventionally, in the schematic diagram of the distribution system management system of FIG. 1, the power generated from the nuclear power plant 10 or the thermal power plant 12 is passed through a plurality of substations 14 and 16 along a plurality of switch lines along the grid 25. It is supplied to each home 26, factory 27, building 28, etc. through 17-23.

These distribution systems are connected like spider webs through processing or underground.

Such failure and maintenance of the distribution system are managed by the competent electric power corporation, etc., and the system of the distribution system is almost all done by manual work. In other words, if the current distribution facility is in distribution, or the distribution plan for the facility or facility in the distribution plan is drawn up and managed, and if there is a change in the distribution system, it will be manually corrected, supplemented, or rewritten. .

Therefore, conventionally, the system diagram related to the distribution system should be produced by drawings and status panels, etc.In the case of the wiring diagram, the creation and management of the disconnection diagram for each line should be made. Tracking was also time consuming.

In order to solve the problems described above, the present invention is based on the system progress diagram including the high pressure and the low pressure, the disconnection diagram for each line, and the like on the basis of the system diagram and the National Geographic Information System (NGIS). An object of the present invention is to provide a distribution system management system for easily managing a distribution system by preparing and making a database.

In addition, the present invention is computerized to manage the various history of the distribution equipment, the field equipment of the protective device and the switchgear by type and type, and the simulation, operation of the operation of the switchgear for processing according to the failure and work of the distribution line It manages the history and prints out in various sizes, and it is a web browser type distribution system that enables the sharing and widespread use of the system by users of multiple branches and departments using the local area network (LAN). The purpose is to provide a management method.
