摘　　要：提出了一种利用接地故障产生的高频暂态电压进行故障定位的方法,该方法仅利用初次到达测量端的高频暂态波,而完全不需要反射波,从而可以有效避免故障点和对端母线的反射波之间的区别问题。大量的ATP/EMTP仿真分析验证表明,该方案精度较高,故障定位误差在线路总长度的1%之内。A fault location method based grounding fault is proposed. This method only on the high frequency transient voltage generated by the uses the high frequency transient wave of the first arrival measurement, and it doesn＇t need the reflection wave, thus, the problem of the difference between the fault point and the reflection wave of the end bus bar can be avoided effectively. A large number of ATP/EMTP simulation analysis shows that the method has high accuracy, and the average error is less than 1% of the total length of transmission line.
