摘要

为了实现对核电站数字化仪控系统的验证,缩短调试周期、提高调试效率,在非能动安全型压水堆核电站数字化仪控系统仿真验证平台上,对给水调节控制方案进行了动态特性分析和逻辑预演.采用先进的图形化建模工具对给水调节的控制逻辑和控制策略进行了1∶1仿真,并通过核电站典型瞬态测试对控制方案进行了可行性的仿真验证.验证结果表明了该给水调节控制方案是可行的同时,也对其跟踪逻辑和策略提出了改进优化建议.%In order to implement verification and validation (V&V) for digital I&C system of nuclear power plant,and shorten the commissioning period,enhance the efficiency,dynamic characteristic analysis and logical preview of the feedwater control scheme are carried out on the simulation V&V platform of the digital I&C system for passive safety pressurized water reactor nuclear power plant.By adopting advanced graphical modeling tools,1∶1 simulation is conducted for control logic and control strategy of feedwater regulation,the simulation V&V is carried out through typical transient test of the nuclear power plant for the control scheme.The results show that this feedwater regulating control scheme is feasible.Some of the suggestions for improving the tracking logic and strategy are also given.
