Harmonic Fault Diagnosis Method of Communication Power Metering Equipment Based on Wavelet Packet Decomposition
Traditional harmonic fault diagnosis methods are usually based on spectral analysis and Fourier transform,but in practice,harmonic faults cannot be accurately identified due to the nonlinear and temporal variation of the signals.Therefore,a harmonic fault diagnosis method of communication power metering equipment based on wavelet packet decomposition is proposed.In the process of collecting the harmonic signal of the metering equipment,and the wavelet packet algorithm is combined to extract the features related to the harmonic fault.The experimental results show that the diagnostic efficiency of the harmonic fault diagnosis method based on wavelet packet decomposition is higher than the conventional methods.
