Abstract
This work presents a performance comparison method for wavelet based compression of three-phase signals. Input signals are simulated on ATP software, while the mother wavelets, compression thresholds and transform detail levels are changed. Thousands of compressed output signals are thus obtained, and the compression rate and error are calculated. These performance indicators are analyzed, based on which a group of wavelet compression parameters is obtained.
