摘要
应用Daubechies小波对电力电缆故障测试波形进行多分辨率分析 ,仿真表明所采用的方法在时域和频域均具有良好的检测性能 ,能够刻画信号的全局和局部奇异性变化的特点 ,指出小波变换作为一个强有力的判据使结合波形特点的自动测距变得容易。
In this article we use Daubechies WAVELET method to analyse power cable fault experimental wave, this lead to an conclusion that wavelet method is good in both time domain and frequency domain to analyse testing data. WAVELET method can well discriminate altering character of both full scale signal and partial signal, which shows that WAVELEVT method will make automatically fault location more easy.
