Power distribution network centralized feed line automatic fault processing method

Abstract

The invention discloses a power distribution network centralized feed line automatic fault processing method. The method comprises the following steps: step one, positioning faults, i.e., according to fault information detected by each distribution terminal or each fault indicator, through combination with fault information of a transformer station, starting a fault processing program, and determining fault types and occurrence positions; step 2, generating fault strategies, i.e., a master station generating two or more than two accident isolation and power supply recovery operation schemes; and step three, processing the faults, i.e., based on the fault strategies generated in the second step, carrying out remote-control execution and assisting in displaying corresponding results, such that the purposes of rapid fault isolation and power supply recovery are realized, the fault positioning accuracy of a power distribution network is improved, the fault processing time of the power distribution network is shortened, fault recovery of the power distribution network is optimized, and the technical effect of fundamentally improving the power supply reliability of the power distribution network is achieved.

Description

technical field [0001] The invention relates to the field of distribution network automation processing research, in particular to a distribution network centralized feeder automation fault processing method. Background technique [0002] Feeder is a term in the distribution network, it can refer to the branch connected to any distribution network node, it can be a feed-in branch or a feed-out branch, the distribution network is composed of overhead lines, cables, towers , Distribution transformers, isolating switches, reactive power compensation capacitors and some ancillary facilities, etc., play an important role in the distribution of electric energy in the power network. [0003] In the existing technology, when a fault occurs in the distribution network, the artificial alarm information or the information reported by the regional station is mainly used to locate the fault, and then the fault is analyzed and processed manually, which needs to be processed manually to di...
