摘要

线路故障定距一直是电力系统重要而难于解决的课题。针对传统单端故障定距算法信息量不足的缺陷，文章提出了一种利用故障电弧特性的单端故障定距算法。该算法仅利用线路一端的电压、电流采样值，且不受故障点位置、故障发生时电源相位等的影响。数值仿真试验和模拟试验的结果表明该算法有较高的准确度。

Abstract

Fault location is a difficult problem to solve in power system. The conventional single-terminal fault location algorithms have big error because of insufficient information. A kind of single-terminal algorithm using the characters of fault are is presented in the paper. Voltage and current data from one terminal is used only in this algorithm and the fault distance and fault phase of sources do not affect the precision of this algorithm. Verified by simulation and test

this algorithm has relatively high precision.
