建立了压水堆核电厂蒸汽排放控制系统及其控制对象的实时仿真模型,包括蒸汽发生器及相关管道阀门的数学模型。在此模型基础上,编制了压水堆核电厂蒸汽排放控制系统动态特性的实时仿真程序,并对该控制系统模型进行了闭环稳态和瞬态等工况的可视化动态实时仿真。仿真结果表明,程序输出与实际系统响应趋势一致,仿真软件能实时输出蒸汽排放控制系统的动态响应曲线,表明该软件能满足蒸汽排放控制系统实时仿真的要求。

In order to analyze the dynamic response performance of steam dump control system,the real-time simulation model of steam dump control system in NPPs is established.Based on this model,a real-time calculation code is programmed to dynamically simulate the behavior of the control system.The visual and real-time simulation for closed loop condition,such as steady state and transient state,is performed with this code.The agreement between simulation results and the practical response of the control system is reasonable.The real-time property of the model can be verified for the steam dump control system.
