摘　　要：将小波分析方法应用于电力系统故障信号分析和处理，获得了小波包分析和数据压缩处理两个方面较好的结果。在给出小波分析概念的基础上；较为详细地讨论了离散二进正交小波算法，并利用该算法分析了电力系统故障信号，获得了较好的结果。Awavelet analysis has been applied in power system fault signal analysis and processingwith good resuIts obtained in both wavelet packet analysis and data compression,The S. Mallat algorithm is discussed and used in apower system fault signal analysis The situationof and prospects for the application of the wavelet analysis in power systems are also dis-cussed.
