摘要

基于Petri网理论某第三代核电站主给水系统建立了工况模型。通过对主给水系统原理及运行工况的分析

验证了该模型表征主给水系统动态特性的正确性;通过对该工况模型的进一步演化建立了主给水系统的Petri网故障模型

并计算得到主给水系统的可靠性指标为0.993

与实际系统设计中冗余设置结果相符

为核电站主给水系统的动态特性描述及可靠性计算、分析提供了一种新的方法。

Abstract

On the basis of the Petri net theory

the model for main feed water system of a third generation nuclear power plant was established.Analysis on system operation proved this Petri condition model was valid and accurate.In addition

the fault Petri net model for main feedwater system was built by the model deduction.The reliability index of the main feedwater system was calculated as 0.993

which was consistent with the redundancy of the actual system design.The novel Petri net model and the new reliability evaluation method provided an important reference for performance evaluation of nuclear plant systems.
