| Abstract: | A novel method was propsed of power quality transient disturbance detection and analysis using wavelet-multiresolution signal decomposition. Through the simulation of serval power quality transient disturbance detection, such as oscillation transients, impulsive transients and momentary interruptions, the result show that this method has good detection performance. It could be used in transient signal detection and time-frequency analysis, and it could be also used in others non-stationary signal processing. |
