摘　　要：根据质量和能量守恒基本原理,运用一系列微分方程描述凝汽器的工作过程,从而建立凝汽器的动态数学模型,并对300MW机组凝汽器几种典型工况下仿真结果进行分析。仿真试验表明,该模型能正确反映机组的动态特性,对凝汽器的运行具有指导作用。A method of development of dynamic mathematical model of the condenser is presented based on the conservation of mass and energy and being described by a series of differential equations. The paper analyzes the simulation consequence of the condenser in 300MW unit under several typical cases. The results of simulation tests indicate that the model can reflect the dynamical characteristics of the power units and direct the operation of the condensers.
