英文摘要：

The principle of wavelet neural network is analyzed. The wavelet neural network is lad to power network fault diagnosis and tested on four bus-bar systems. The simulation results show that the method is of fine fault diagrmesis ability. The power fault diagnosis method based on wavelet neural network has simple principle and better result compared with the method based on BP neural network.
