摘　　要：采用集中参数法,通过简化计算及现场仿真机运行数据,建立了核电机组除氧器水位动态特性数学模型,并对模型进行了凝结水流量、高压缸抽汽流量等扰动仿真试验,将仿真试验结果与某核电站仿真机的仿真结果进行比较。结果表明,仿真结果与核电站仿真机的仿真结果相符,且两者拟合程度较高。On the basis of simplified calculation and field simulator＇s operation data,the lumped pa- rameter method was employed to establish a mathematical model for investigation on dynamic characteristics of deaerators in nuclear power units. Moreover, disturbance condensate flow,high pressure cylinder＇s extraction flow and other variabl conducted,and the results were compared with the simulator＇s results of a shows that, the two results agree well with each other, and they both have simulation tests about es for this model were nuclear power a high fitting plant. It degree.
