【Abstract】 A set of 25 kW dish-stirling solar thermal power generation system was adopted as the research object. First of all,each part of the system was modeled mathematically. Thermal efficiency and exergy efficiency of each component were calculated under the typical working conditions. Secondly,the performance of each component was evaluated and connected in series to the whole system. Finally,the performance of the whole dish-stirling solar thermal power generation system was analyzed and compared with the actual dish solar power station operating conditions. Through these works,to judge the feasibility of the model,the key link of the system energy loss was found out,which could and provide the basis for the improvement of the system in the future.更多还原
