On the Harmonic Detection Based on Wavelet Package Analysis
Yi Hong · Sichuan University of Arts and Science Journal · 2007
This paper proposes a new method for the harmonic detection based on wavelet packet analysis.First it discusses the semaphore dissociation and implementing method based on wavelet package analysis,and next discusses the method for harmonic analyses based on differential frequency selective and sub-band filter.Finally it sets forth a new method for synchronous detection which is used to detect voltage flicker and harmonic analysis.
