Harmonic Analysis System of Power Network Based on Wavelet Transform

摘要：

The harmonic analysis system of power network was developed based on wavelet transform by using the virtual instrument. The system consists of sensors, signal conditioning circuits, data acquisitions and computers. Within the system, the wavelet packet was adopted to analyse harmonics and locate the distortion point by means of the MATLAB script node in LabVIEW, in which the signals were divided into multi-frequency band according to the power signal character, and the frequency band was selected adaptively so as to promote the time-frequency resolution of signals.
