配电网故障定位统一矩阵算法的改进

Revision of Unified Matrix Algorithm for Fault-Location Detection in Distribution System

文献[2]中提出了基于FTU的配电网故障定位的统一矩阵算法,但将该算法应用于辐射状馈线和树状馈线的末端进行故障定位时,会无法判断出故障区域.因此提出在该算法中采用零编号的方法,结果表明该方法可以使得应用该算法对辐射状线路的末端和树状接线的末端进行故障定位时,不存在盲区.

Applying the united matrix algorithm for fault-location detection in distribution system to the end of radiation-shape feeder and tree-shape feeder,it is impossible to judge the fault -location. Therefore, a new method adopting zero coding in this algorithm is proposed. The result shows that this method can clear the blind areas.
