摘要
相位信息是电力系统的一个重要特征,正交或双正交的复小波是实时提取电力系统中相位信息的有力手段。本文在最佳提升格式的基础上,提出了一种双正交复小波的生成方式,通过具体实例,证明了该方法的可行性。
Phase information is one of emphasis characters in the power system orthogonal or biorthogonal complex wavelet is strong means to extract phase information in the power system in time. Based on the uniqueness of the shortest lifting scheme presents a means to construct biorthogonal complex wavelet furthermore examples how to design compactly supported biorthogonal complex wavelet by this procedure are given.
