| Abstract:To detect early faults of ship power systems timely, through the combination of the multi population genetic algorithm and the BackPropagation (BP) neural network algorithm, a fault diagnosis method for ship generators based on a multi population genetic neural network algorithm is proposed. The fault diagnosis for real examples is done by the algorithm. The results show that the algorithm can effectively overcome the weaknesses of BP neural network that has a slow convergence speed and is prone to a local minimum value. The algorithm is of strong global search capability and a rapid optimization speed, and is of certain application prospect. |
