基于幅频特性的复值小波构造及其在电力系统信号分析中的应用
The construction of complex wavelets based on amplitude-frequency characteristics and their application for fault signal analysis in power systems
摘要
Abstract
In this paper,a method of the construction of complex functions and their transforms are presented.The complex wavelet functions constructed by means of this method have advantages of good performance in frequency localization and better veracity in extracting characteristic parts of signals.Because complex wavelet transforms can exactly identify amplitude and phase information in signal to be dealt with,they are suitable for detection of fault signals in power system.In this paper,some of failure signals in rotor of generator are analyzed by making use of complex wavelets based on amplitude-frequency characteristic,it is shown that it is an effective method in fault signal analysis in power system.关键词
