摘　　要：针对直接空冷凝汽器的特性,以凝结换热机理为基础,通过合理的简化,建立系统变工况的动态仿真模型。以600 MW直接空冷机组为例,得出迎面风速、环境温度、排汽量与汽轮机背压的数据,绘制了特性曲线并进行了分析,供电厂机组运行时参考。In view of the characteristic of direct air-cooled condenser,based on the mechanism of condensation and heat exchanging,by means of reasonable simplification,the dynamic simulation model of system off-design condition is set.For instance of 600 MW direct air-cooled units,the data of head-on wind speed,circumstance temperature,steam displacement and back pressure are derived.The characteristic curve is drawn.The relationships within them are analyzed to the reference for operation of power plant.
