| Abstract: | Aiming at the problem,the obtain knowledge difficult in the tradition expert system in the circuit breaker failure diagnosis,a diagnostic scheme combining RBF neural network with expert system is proposed. The original network weight and the threshold values are modified by using the concept of confidence level. Then the function used to diagnosis to the new breakdown failure type can be realize.And the problem to obtain the knowledge in the tradition expert system is also solved.The simulation results indi... |
