英文摘要: Concentrating solar power technology is one of the renewable power technologies to meet base-load demand. The freshwater shortage, high cost, lower energy utilization efficiency and dynamic solar irradiation is the main obstacles for the large scale development of the CSP. This project aims to research the water conservation and flexible operation technology of CSP system. Firstly, the research will focus on the mass and thermal transfer performance of several kinds of humidifying air cooling system, and thermodynamic system analysis of the combined solar power and water production system. Then, the thermal energy cooperative transmission between the subsystems of Concentrator-Receiver-power system-thermal storage system-desalination system under strong unstable solar irradiation and time-varying load conditions will be research by the thermodynamic system simulation and experimental research. The research results of the project will decrease the water consumption and improve the operation Flexibility of the CSP system.
