Application for Voltage Small Fluctuation of Power Quality Disturbance Base on Wavelet Transform
Abstract：Because the voltage small fluctuation influences precise instrument requires high stable pressure, the methods of detecting power quality disturbance are introduced. According to multi-resolution analysis theory and Mallat algorithm of wavelet transform, as well as using that wavelet transform has outstanding time-frequency localization characteristics and frequency domain local features. The method of detecting voltage small fluctuations of power quality disturbance based on wavelet transform is proposed. The simulation results show that the method is superior to other methods in respect of detection of voltage small fluctuations.
