Abstract

Empirical Mode Decomposition(EMD) algorithm is the Hilbert-Huang Transform(HHT) of the core algorithm,which relies on the decomposition of the effect of the choice of sampling frequency EMD introduced a new method of selecting the sampling frequency and signal through the simulation experiments show that the method is more complete decomposition of the signal,on the power system harmonic analysis of the practical application of a certain value.
