摘要
小波变换具有良好时域局部化特征,时域窗口随信号的变化自动调整。目前其在电力系统中的应用已较为广泛,文章介绍了小波变换的基本内容,并对其目前在电力系统中的应用进行和概括和总结,提出了发展方向,总体来说,随着小波理论的发展,其在电力系统中的应用将不断深化和扩大。
Wavelet transform has good time domain localization characteristics of time domain window along with the change of signal automatic adjustment. At present its application in power system has become more widely, this paper in-troduces the basic content of wavelet transform, and its current application in power system, and summed up and summa-rized, put forward the development direction, in general, with the development of wavelet theory, its application in power system will continue to deepen and expand.
