摘要

识别第2个反向行波来自故障点还是对端母线是实现单端行波故障测距的关键

对此

提出一种识别第2个反向行波性质的新方法。通过分析4种类型的行波传播路径

得到透射线模行波与非透射线模行波到达测量端的时间顺序

从而辨识出由故障点交叉透射的初始线模行波

再利用初始透射线模行波与第2个线模反向行波之间的极性关系构造了识别第2个反向行波性质的判据。仿真结果表明:所提方法基本不受母线结构、模量衰减和透射模量的影响

具有较好的可靠性。

Abstract

Identification of the second reverse travelling wave reflected from the fault point or the remote-end bus is the key to one-terminal fault location based on traveling wave. In order to overcome this problem

a new method is proposed to identify the nature of the second reverse traveling wave. Firstly

the arrival time sequence of coupling and non-coupling line-module traveling wave is obtained by analyzing four types of traveling wave propagation paths. According to the time sequence

the initial cross coupling line-module traveling wave reflected or refracted from fault point can be identified. Then

the polarity relation between the second line-module reverse traveling wave and the initial coupling line-module traveling wave is used to confirm the nature of the second reverse traveling wave. Simulation results show that the proposed method is not affected by busbar structure

traveling wave attenuation and coupling traveling wave

the sufficient reliability is achieved.
