Empirical mode decomposition （EMD）method is a novel non-stationary signal analysis method. Based on the non-stationary characteristic of low frequency oscillation signal, this paper introduces the application of EMD method in analyzing the characteristic of low frequency oscillation. The simulation results showed that this method can accurately draw the characteristic of the low frequency oscillation in power system.
