Abstract:A dynamic mutation operation is introduced to the particle swarm optimization(PSO), and the improved PSO and back propagation(BP) algorithm is combined to form hybrid algorithm for training artificial neural networks. Applying the hybrid algorithm to the transformer fault diagnosis, the results show that this hybrid algorithm has a faster convergence speed and higher accuracy. And the diagnostic results show that this hybrid algorithm can improve the accuracy of the transformer fault diagnosis.
