摘要
Abstract
The harmonics produced by the non - linear load have resulted in higher incidences of harmonic distortion in the current waveforms which may distort the system voltage waveforms eventually. The existing methods for detecting the harmonic and reactive power are analyzed in this paper. Furthermore, due to the minimum energy losses, the related voltage and current is obtained. Taking the minimum energy error as the criterion, a harmonic and reactive power detecting method is put forward based on the waveform similarity theory. The validity and accuracy is verified by the PSCAD simulation.关键词
