主动配电网智能分布式馈线自动化故障定位方法
Fault Location Method for Intelligent Distributed Feeder Automation of Active Distribution Network
摘要
Abstract
With the high penetration of distributed generators (DGs),the radial structure of conventional distribution system will change to multi-terminal type.Influenced by the short-circuit current injected from distributed generators,fault location scheme for distribution network based on over current protection may be invalid.The fault current characteristics for active distribution network is investigated,and the relationship between the differences of current phase and fault location is found,a novel distributed feeder automation (FA) fault location method of active distribution network is presented.With this method,each terminal excutes distribued calculation according to the fault over-current and current phase of the terminal itself and neighboring terminal to achieve fault location.This method is applicable for complex active distribution network with multi-source,multi-branch and multi-contact,and it can locate the fault exactly since it does not depend on voltage and each terminal uses distributed decision.Finally,the feasibility and effectiveness of the proposed method is verified by DIgSILENT simulation analysis and engineering example.关键词
