| Abstract: | Based on the wavelet decomposition, ways and means of detecting fundamental component and harmonicsare explored. The simulation results showthat the method is valid to a certain extent. In addition,simulation examples arecitedin illustration of the error when the fundamental component is extractedby use of the wavelet decomposition.Afterthe analysis of the frequency domain characteristics of several wavelet functions, the main causes of yielding error in harmonics measurement based on the wavelet transformare pointedout. |
