By detecting signal strangeness and reducing signal noise, the paper arrives at the maximum value of the detected signal, thus the fault location of the traveling wave signal is achieved.
通过对信号奇异性的检测和对信号的消噪，提取出了被检测信号的模极大值，进而实现了行波信号的故障测距。
The classic analysis of high-frequency (HF) protection only takes account of the channel delay effect of HF signal, neglects the delay effect of electric traveling wave.
高频保护传统分析方法仅考虑高频信号在通道中的延时效应，没有分析电气量的行波延时效应。
This paper shows some new methods just like residual flow increment, signal tracking, traveling wave, transient state and complex selection.
本文列举了适用于谐振接地系统的各类新兴方法。如残流增量法、注入信号寻迹法、行波法、暂态法以及综合选线法。
