| 摘 要： | 从实用化的角度出发,针对配电网自身的特点,提出了利用C型行波原理进行配电网故障定位的方法。该方法不利用故障发生时自身产生的行波信号,而是在故障后在故障线路首端离线注入高压脉冲信号,采集线路首端的行波信号,通过分析行波的特征,从而实现故障定位。针对分析行波信号时存在的难点,提出了解决办法。设计了故障定位实现流程。对现场实验进行了详细分析。证明了该方法的可行性。

| Abstract: | For the sake of practical usage,according to the characteristic of distribution network,fault location method based on C-type traveling wave is proposed.This method dose not use the traveling wave that the fault generated,it injects high voltage pulse signal off-line on the head of the fault line after fault appeared,and collects traveling wave on the head.Analyzing the characteristic of traveling wave fault location can be realized.As for the existent difficulties of analyzing traveling wave signal,the method of solving is put forward. The process of implementation is designed and the experiment on-the-spot is analyzed in detail.The feasibility of this method is proved. |
