Power distribution automation terminal-oriented topology generation method and system

Abstract

The invention discloses a power distribution automation terminal-oriented topology generation method. The method comprises the following steps of S1, obtaining basic data: obtaining attribute data of each device in a power distribution network, a geographic map and a schematic diagram of a power grid, represented by vector structures, and various image device data represented by lattice structures from a GIS of the power distribution network by a power distribution automation system master station; S2, analyzing the basic data: analyzing the attribute data of each device by the power distribution automation system master station, distributing and connecting devices through the geographic map and the schematic diagram of the power grid, represented by the vector structures, obtaining a physical connection condition of each device in the power distribution network, obtaining various switch blades in the power distribution network, and finally summarizing and sending the analyzed data to the power distribution automation system master station; and S3, generating a dynamic topology: establishing a topology model for the summarized data by the power distribution automation system master station. The method is simple and convenient to realize, and effectively improves the management efficiency, thereby being suitable for popularization.

Description

technical field [0001] The present invention relates to the field of topology generation method and system technology in the field of power system and automation thereof, and in particular to a topology generation method and system for power distribution automation terminals. Background technique [0002] The distribution terminal refers to the remote distribution automation terminal, which is a general term for various remote monitoring and control units installed on the medium-voltage distribution network site, mainly including feeder terminals, station terminals, distribution transformer terminals, etc., and the distribution master station has More powerful computing power, mastering the topology of the power grid, can plan and design new operation modes when permanent faults occur on the line, isolate fault points, and minimize the scope of power outages. In order to liberate the computing power of the main station and improve the fault response and processing speed, it ...

Problems solved by technology

Feeder automation is an important part of distribution network automation. Its function is to monitor the status of feeder section switches and tie switches, feeder current and voltage in real time, and realize remote or local closing and opening operations of line switches. The distribution automation terminal can not provide topology to meet the existing management, so we propose a topology generation method and system for distribution automation terminal
