英文摘要：

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.
