Paper Abstract
To improve the performance of power quality (PQ) disturbances classification, a novel approach using wavelet neural
network is proposed. The wavelet transform can accurately localizes signal characteristics in time-frequency domains
The wavelet transform is utilized to extract feature vectors of different PQ disturbances. These feature vectors then are
applied to the neural network for training and disturbance pattern classification. By comparing with classic neural
network, it is concluded that the proposed neural network has better data driven learning and local interconnections
performance. The research results between the proposed method and the other existing method are discussed and the
proposed method can provide accurate classification results. The simulation results demonstrate the proposed method
gives a new way for identification and classification of power quality disturbances.
