Distributed Diagnosis Strategy and Its Application in Nuclear Power Plants

Defense Key Discipline Laboratory of Nuclear Safety and Simulation Technology, Harbin Engineering University, Harbin, 150001, China

摘要: 核电站运行状态的监测与故障诊断直接关系到核电站的安全性、可靠性和经济性。针对核电站故障诊断特点,本文提出了一种分布式故障诊断方法,开发了反应堆冷却剂系统分布式故障诊断系统(RCSDFDS)。实验测试表明,RCSDFDS不仅能够对单一故障进行及时、准确的识别,而且对多重故障也具有良好的识别效果。

Abstract: 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.
