摘要
提出利用线路故障产生的暂态行波实现配电架空线与电缆混合线路单端测距的方法。该方法分2步确定故障点:首先根据故障行波的传播特性,提出新的判据以确定故障区段,此判据根据特征波的逻辑运算结果确定故障区段;然后在定段的基础上再实现准确定位。
A fault location technique is presented for distribution overhead lines and underground cables based on single terminal method with transient traveling waves caused by fault. The method divides into two steps. First, a new criterion for determining fault section based on character of fault traveling waves is proposed. The fault section is obtained with the result of logical calculus of the characteristic waves. Then the fault position is accurately obtained after the fault section determined.
