摘　　要：太阳能光热发电是自由活塞斯特林热机技术的重要应用方向之一。为降低碟式-斯特林太阳能热发电系统成本,本文提出并实验研究了一种焦点固定型碟式-自由活塞斯特林太阳能热发电系统。初步实验结果表明:自由活塞斯特林发电机起振时对应的吸热器壁面温度为345℃。当太阳辐射强度在760 W/m^(2)附近时,吸热器壁面温度在650℃以上,发电机的输出功率可达1320W。本工作验证了低成本的多碟聚光器用于碟式-自由活塞斯特林太阳能热发电系统的可行性,并为下一步系统优化指明了方向。Concentrated solar power(CSP)is an important application area of free-piston Stirling heat engine technology.In order to reduce the capital cost of a dish-Stirling CSP system,this paper proposed and experimental studied a focus-fixed dish-free piston Stirling CSP system.Preliminary experimental results show that the free-piston Stirling generator was started up when the wall temperature of receiver reached 345℃.When the direct normal irradiation was around760 W/m^(2),the wall temperature of receiver was higher than 650℃and an output electric power of 1320 W on the free-piston Stirling electric generator can be obtained.This work validated the feasibility of the focus-fixed dish-free piston Stirling CSP system and enlightened the future research pathways.
