摘要
根据核动力装置的冷凝器结构及工作特性,给出了适用于冷凝器动态特性实时仿真数学模型。该模型可用于冷凝器稳态和动态的仿真,并能够预测冷凝器内蒸汽和凝结水的流量以及蒸汽、凝结水、管壁和冷却水等的温度。用本文的仿真模型对正常运行工况及事故工况进行了仿真计算,将仿真结果与系统设计值进行了比较。结果表明,该模型能够满足核动力装置冷凝器实时仿真的要求。
A real-time model describing the dynamic behaviour of a nuclear power shell-and-tube condenser is presented, according the structure and working characteristics of the condensor. The model can be used under steady-state as well as transient conditions, and is also able to predict vapour and condensate flow rates, and the temperatures of the vapour, condensate, wall and coolant. The results of several simulations are analyzed after the simulation of normal and malfunction state. The results show that the model can be used for real-time simulation of nuclear power condensers.
