电力系统暂态行波信号的奇异性检测分析

Detection and Analysis of Singularity of Transient Travelling Wave Signals in Electric Power System

文章根据电力系统故障暂态行波信号的奇异性特点与小波分析在时域和频域同时具有良好的局部化特性 ,选取了具有紧支集的B—样条小波对暂态行波信号作小波变换 。

Considering the singularity property of tansient travelling wave of power systems and wavelet analysis has excellent location nature in time and frequency domain,a compactly support B-spline wavelet is selected for the transient travelling wave's wavelet transform in the paper.A method to detect the singularity of travelling wave is presented by wavelet transform maxima.
