摘要
分析了目前配电网故障定位算法存在的问题,针对配电网实际运行方式提出一种适用于单电源配网多重故障的定位改进算法,消除了末端故障的定位盲区;根据电流的连续性原理,确定信息上传失败的开关是否流过故障电流,综合各种可能的故障区域增强容错能力;给出了包括源点的选择、开关跳闸后的处理等的软件实现步骤以及实用化处理手段。
The problems of present fault-location algorithm of distribution network are analyzed,and a new algorithm applied to multiple fault of single supply network is proposed aiming at actually running,which has no blind areas for end fault.The electric current of the switch whose information uploading failure is identified according to continuity principle of electric current.The algorithm integrates every possible section to enhance its fault tolerant property.This paper describes the implementing steps in software and the practical means,including the selection of the source point,handling after bus switch or loop switch tripping.
