Distribution Network Fault Restoration Optimal Reconfiguration Method Based on Critical Path Method

Abstract

The invention discloses a power distribution network fault recovery optimization rebuilding algorithm based on a critical path method. After a fault occurs in a power distribution network, a power supply recovery system analyzes and judges the fault occurring in the power distribution network in real time according to relevant information, a correct effective sound power-loss area power supply recovery strategy is provided to help a dispatcher to accurately determine the fault position and isolate a fault area to quickly recover power supply in non-fault areas. Optimization recovery of power supply of non-sound areas of the power distribution network is facilitated, the scheduling level of the power distribution network is improved, power failure time is reduced, safety, reliability and economy of the power distribution network are improved, and good application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a distribution network fault restoration optimization reconstruction method based on a critical path method. Background technique [0002] In recent years, the State Grid Corporation of China officially announced the "Strong Smart Grid" plan to the outside world, and with the participation and cooperation of people from all walks of life, it has carried out a lot of scientific research and practical work in related fields, and has achieved certain results. It can be said that, my country's smart grid construction has been fully rolled out. [0003] Distribution network automation is the use of modern electronic technology, communication technology, computer and network technology to realize the modernization of monitoring, protection, control and distribution management in the normal operation of the distribution system and in case of accidents. With the rapid development of t...
