Abstract
Aiming at the problem that FFT can’t detect the transient signal, and wavelet analysis is easy to produce energy leakage and frequency aliasing in power harmonic detection, the paper gives a new algorithm which combined wavelet with information entropy in order to design a new function that is wavelet energy entropy, it is used to extract informations of transient signal effectively in power system. According to the harmonic characters in power system, a mathematic model is done based on it. The simulation results in Matlab indicate that the new algorithm is validated in transient signal detection.
