摘要
分析了原有的配电网矩阵法故障定位中存在的问题,提出一种适用于辐射状网及开环运行环网的配电网故障定位算法。该算法仍以矩阵分析为核心,通过网络拓扑形成网络关联矩阵,然后结合馈线终端设备(FTU)上传的故障信息形成故障判定矩阵,判定方法简单。它不仅可以实现配电网单一故障的快速定位,而且对末端故障及多点故障也可以做出准确判断。通过编程实现算法,并用不同区域故障的模拟验证了算法的有效性。
This paper analyzes the problems in fault location for the original distribution network matrix,proposes a fault location algorithm applying to radial network and ring network running with open loop,an algorithm with matrix analysis at the core which formulates network association matrix by network topology and fault judgment matrix,easy to judge,by fault information uploaded by feeder terminal unit（FTU）.This method can not only realize rapid location of single fault,but accurately judge end and multi-fiber fault of distribution network.The algorithm is programmed and is proved to be effective by simulating fault in different areas.
