以大汉MW级塔式太阳能热发电系统过热型腔式吸热器为研究对象,采用模块化建模方法、根据吸热器的工作机制和热力学定律,建立过热型腔式吸热器的全工况动态仿真数学模型。模拟大汉兆瓦级塔式太阳能热发电站过热型腔式吸热器的动、静态特性。给出大汉兆瓦级塔式太阳能热发电过热型腔式吸热器太阳能辐照的阶跃扰动响应曲线,得出的结论对塔式太阳能热发电电站过热型吸热器的设计、塔式太阳能热发电电站运行策略的制定具有一定的指导意义。

The water/steam superheated cavity receiver that is used for the MW Dahan solar thermal power tower demonstration plant was studied theoretically.A dynamic mathematical simulation model for the receiver was developed based on the three main section of the superheated cavity receiver.By simulating the dynamic and static characteristics of the receiver,a group of disturbance response curves on the radiation flux were given.The conclusions could be referred for the design of superheated cavity receivers and identification of the operational strategy of the solar thermal power tower plant.
