| Abstract: | To discusse the principle of the wavelet multi-resolution signals decomposition,a novel method was proposed of power quality transient disturbance detection and analysis using wavelet multi-resolution signal decomposition.Through the simulation of several power quality transient disturbances detection,such as voltage sag,voltage interruption and impulsive transients,the results show that this method has good detection performance. |

| Keywords: | power quality wavelet transform sub-band filter multi-resolution analysis |
