Article Preview

Inter-harmonic wave is one of most important factors to influence power quality in power system, which is harmful to the power system and power equipment. Db5 wavelet, sym4 wavelet and Fourier transform have been applied to analyze the inter-harmonic of power system, respectively. The simulation results show that Fourier transform fails to analyze the inter-harmonic, while db5 wavelet and sym4 wavelet can separate the fundamental wave from inter-harmonic wave. By Comparison, db5 wavelet is more precise and effective than sym4 wavelet to separate the fundamental wave.
