摘要
输电线路是电力系统的重要组成部分,输电线路的可靠运行关系着国民经济的健康良好发展。输电线路分布面积广、范围大,如何快速准确地分析判断线路故障位置,排除故障,对于保障输电线路的可靠运行是十分关键的。本文主要对根据多点电流测量的输电线路行波故障定位法进行了分析和讨论,该方法相对传统行波分析,对于故障点位置的判断精度有较大改善,对于输电线路的故障定位有一定的参考价值。
Transmission line is an important part of the power system, the reliable operation of the transmission line is related to the healthy development of the national economy. The distribution area of the transmission line is wide, the range is large, and the analysis of the fault location and fault location is very important for ensuring the reliable operation of the transmission line. In this paper, the fault location method for transmission line traveling wave based on multi point current measurement is analyzed and discussed, relative to the traditional traveling wave analysis, the accuracy of the fault location is improved, and the fault location of the transmission line has a certain reference value.
