Abstract

In order to improve the diagnosis performance of Loss of Coolant Accident（LOCA）,based on Back Propagation（BP） algorithm study,a fault diagnosis network is established based on Particle Swarm Optimization（PSO） algorithm in this paper.The PSO algorithm is used to train the weights and the thresholds of neural network,which can conquer part convergence problem of BP algorithm.The test results show that the diagnosis network has higher accuracy of LOCA.
