摘　　要：在槽式太阳能光热电站中,集热系统负责收集太阳辐射热量,通过反射镜聚焦,加热集热管内导热介质,使加热后的导热介质进入到蒸汽发生系统、储热系统工作。集热系统是整个槽式太阳能光热电站的重要系统之一,集热效率对发电效率有着至关重要的影响。文中通过对影响槽式集热系统的热膨胀进行分析计算,并提出补偿措施,提高集热器的集热效率。In a parabolic trough CSP plant, thermal collection system collects thermal energy using reflection mirrors to focus solar energy. The heat transfer fluid inside the absorbers is heated and then flows to steam generation system and thermal storage system. The thermal collection system is one of the important systems in the CSP plant and has a critical influence on the power production efficiency. This paper analyzes and calculates the thermal expansion of the collection system, and the compensation measures are brought uo to imnrove thermal collection efficiency.
