Detection and Location for the Transient Power Quality Based on Wavelet Transform

The paper provides insight study of transient power quality disturbance detection and location of the wavelet transform.First,analyzed the basic principles of wavelet multi-resolution and fast calculation method,and then studied the wavelet transform and sudden-changed signals,noise correlation.On this basis,detailing the process of the application of wavelet transform for transient power quality disturbance detection and location of the principle.And finally,using Matlab software to simulate the process,it gave the simulation results of a variety of power quality disturbance detection and location of detection and location.Theoretical analysis and simulation results show that application of wavelet transform of transient power quality disturbance detection and location has accurate,real-time,easy to implement,etc.,it is an ideal of transient power quality disturbance detection and localization.
