For the extraction requirements of non-linear and non-stationary transient composite disturbance signal of the power system, EMD method is applied to decompose these signals from characteristics of time scale, and to realize the self-adaptive dividing of the signal band, and then on the basis of which, Hilbert transformation is conducted and the characteristics of time, frequency and amplitude of each disturbance signal is extracted. Simulation results show that this method has better… CONTINUE READING
