摘　　要：核电站在正常运行过程中,可能会由于设备故障、人员技能不足、人因失误等原因导致机组非预期的保护动作,例如甩负荷、停机、停堆等,这对核电厂的安全性、经济性以及运行稳定性造成较大不利影响。事件原因的快速准确定位对事件响应的有效性和机组的安全经济运行具有重要意义。本文介绍了一种核电厂运行事件原因智能分析方法,以运行事件为切入点,设计并构建专家知识库,以此为核心并辅以动态不确定因果关系推理算法,实现核电厂运行事件原因的智能诊断与定位,该方法适用性强,具有较高的应用价值。During normal operation of Nuclear Power Plant, unexpected protective actions, such as turbine runback, turbine trip, reactor trip etc, may actuated by equipment malfunctions, personnel skill defects, human reason mistakes, etc, which would make adverse impact to the safe, economical, stable operation of nuclear power unit. Locating the reason of event rapidly and accurately has great significance for the effectiveness of event response and the safe, economical operation of nuclear power unit. This paper introduces an intelligent analysis method for diagnosing the reason of operation event. Taking operation event as the entry point, it designs and establishes the expert knowledge base and take it as the core, with the supplement of reasoning algorithm based on dynamic uncertain causality theory, to realize intelligent diagnosis and location to the event reason. This method is widely applicable and valuable in nuclear power field.
