Distributed Diagnosis Strategy and Its Application in Nuclear Power Plants

State monitoring and fault diagnosis are directly related to the safety,reliability and economy of nuclear power plants.Considering the fault diagnosis characteristics of nuclear power plants,this paper presented a method of distributed fault diagnosis and designed the Distributed Fault Diagnosis System of Re-actor Coolant System（RCSDFDS）.Experiments show that RCSDFDS is able to identify the single fault timely and accurately,and is with reasonable identification result for multiple faults.
