摘要
为提升单相接地故障定位精度,提出 110 kV及以上输电线路单相接地故障点自动定位方法.采集110 kV及以上输电线路故障信号,并使用行波信号对其进行提取分析,基于故障行波信号测量故障距离,定位单相接地故障点.测试结果表明,该方法能够实现高精度的故障定位,应用效果较好.
Abstract
In order to improve the accuracy of single-phase grounding fault location,an automatic location method for single-phase grounding fault points of 110 kV and above transmission lines is proposed.The fault signals of 110 kV and above transmission lines are collected,and the traveling wave signals are used to extract and analyze them.Based on the fault traveling wave signals,the fault distance is measured to locate the single-phase grounding fault point.The test results show that this method can achieve high-precision fault location and has good application effect.
