摘要
电力系统中存在着各种各样的故障信号和扰动信号。由于电力系统固有的相位特性,用实小波不能检测出信号中的相位信息。为此,采用复小波检测电力系统中的信号,用已有的简单信息和拓展的复合信息分析,并用谐波检测作为例子,取得了较好的效果。
In power system, all kinds of fault signals and disturbed signals can be found. Due to inherent phase characters of power system, phase information can't be detected in the signal with real wavelet. In this paper, complex wavelet was used in power system to detect signals that were analyzed with simple signals and additional compound signals. it is proved good effect with the example of harmonic detection.
