摘要：
For the extraction requirements of non-linear and non-stationary nature of the transient composite disturbance signal of the power system, EMD method is applied to decompose these signals from the time scale of its characteristics to realize adaptive signal of the band. And then the characteristics of time, frequency and amplitude of each disturbance signal are extracted on the basis of a Hilbert transformation. Simulation results show that the method has a better analysis result to non-stationary power system disturbance signals.
