凝汽器是核电站汽轮发电机组的主要设备之一，采用仿真手段研究核电站凝汽器的运行特性对于优化设计和运行、提高运行的安全性和经济性具有实际意义。本文以核电站中普遍采用的表面式单流程对分制凝汽器为研究对象，运用分布式热动力学的建模思想，考虑不凝结气体（空气）对换热特性的影响，建立了凝汽器的动态数学模型。通过仿真计算，得到不同控制参数阶跃情况下凝汽器的动态响应，仿真结果与实验结果符合良好，表明所建立的仿真模型正确、合理。

T he condenser is a critical component that affects the efficiency and perform-ance of nuclear power plant .In order to make the condenser work under high efficiency and safety , advanced simulation methods for condensers need to be developed . T he steam surface condenser commonly used in nuclear power plant was taken as the research object .Dissolved gas such as air was taken into consideration .The idea applied in distributed thermodynamic modeling was used to establish the mathematical dynamic model of the condenser ,and then the dynamic responses of condenser to the step change of different control parameters were obtained .The predictions from the models were compared with the experimental data ,and the agreement is satisfactory .It is found that the simulation model established in this paper is correct and reasonable .
