分布式故障诊断策略及其在核电站中的应用

Distributed Diagnosis Strategy and Its Application in Nuclear Power Plants

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。

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 Reactor 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.
