- Abstract
To solve the problem adding white noise cannot be completely neutralized and it is not complete of Ensemble Empirical Mode Decomposition(MEEMD) the paper propose that combine improvement of EEMD and Hilbert transform to detect power quality disturbance. First ,decompose power quality disturbance signals and get intrinsic mode functions(IMF) components. Second ,the IMFs after Hilbert transform to obtain accurate instantaneous characteristic at different times.The simulation results show that the MEEMD method has a clear effect to suppress mode mixing and it also applies to the mixed power quality detection.
