新型电力系统背景下对传统故障隔离技术的融合性研究
Research on the Integration of Traditional Fault Isolation Technology Under the Background of New Power System
摘要
Abstract
The distribution network,as an indispensable part of the power system,is responsible for distributing electrical energy,and plays an important role in the power system.When a fault occurs in the distribution network,it is accompanied by a large amount of fault information,such as fault action information,event timing information,fault indicator alarm information,and fault voltage and current data information.How to fully and quickly utilize the corresponding information to achieve fault location is of great significance for resto-ring power supply.Traditional distribution network fault localization has shortcomings such as insufficient utilization of fault localization information,single fault source information,and fuzzy fault localization results.To address these issues,a distribution network fault local-ization algorithm based on multi-source information is proposed,which fully utilizes the switch information and electrical information generated during faults to achieve accurate fault localization.Firstly,the switch information during faults is used for fault section locali-zation.Then,the electrical information measured during the fault is used to achieve distance measurement and positioning,and precise fault location in the distribution network is enabled by introducing μ PMU measurement data.The research example of IEEE33 node shows that the algorithm has simple principles,accurate positioning,and is not affected by fault type,fault location,or fault line,effec-tively improving the speed of fault recovery in distribution networks and the efficiency of operation and repair personnel.关键词
