Abstract :
Aiming at the non-stationary ,burst characteristic of the transient disturbance in power system, the paper introduce a method using the db4 lifting wavelet transform to detect and locate the power quality transient signal, through analyzing the characteristic that the lifting wavelet is fit for detecting the signal catastrophe point of transient disturbance. Using this method to detect and locate the transient power quality disturbance signals like voltage sag, voltage swell, voltage interruption, frequency offset, transient oscillation, instantaneous impulse and ect. in Matlab simulation environment, and the simulation results show that this method realize the location more accurately to the disturbance signals´ starting and ending time, and the precision error is less than 1.1%.
