A Wavelet Transform Power Harmonic Detection Method Based on DSP
To improve the accuracyof power harmonics detect,a power harmonic detection method based on DSP and a pair of A/D is provided in the paper.Wavelet transform has been widely used in the analysis of power system as a method to analyze digital signals,this paper adopt coefficient dissociation with the wavelet packet transform express harmonic current and voltage values etc.,the power harmonics detect device can send data to a PC through DSP interface,program by mixing VC++and LabVIEW,and achieve real-time pwer harmonis detect.The experiment results show that the wavelet packet transform can analyze the local characteristics of the signal more accurately,and improve the harmonic analysis of real-time and accuracy.
