However, because of the positive sequence of fundamental frequency, there are still some shortages for wavelet transform in the use of harmonic measurement of three-phase dissymmetrical system. A new approach of harmonic measurement based on Period-interleaving of MALLAT arithmetic for dissymmetrical system is put forward. Analysis and experiment based on TMS320LF2407 Digital Signal Processor are made. And the result of experiment reveals that the proposed method based on Period-interleaving is valid in the use of harmonic measurement of three-phase dissymmetrical system.
