| Abstract: | Because of the ability of analyzing transient signal, wavelet transform is being used in the field of harmonic detection and the analysis of power quality. According to the internal and overseas actualities, the harmonic detection methods based on MALLAT arithmetic, wavelet packet, continuous wavelet transform, complex wavelet transform and adaptive wavelet are classified and summarized, and their advantages and disadvantages are analyzed and compared. The wavelet aliasing and virtual instrument based on wavelet transform for the analysis of power quality are discussed. Some problems that need to be solved of wavelet transform are summarized. At last, some opinions of the developing trend of wavelet transform in the use of harmonic detection are put forward. |
| Keywords: | Harmonic detection power quality wavelet transform virtual instrument |
