本文对静止广角菲涅耳透镜与移动复合抛物面聚光器相结合的太阳跟踪系统进行了详尽的研究。聚光光学系统是为建造集成太阳能应用而提出的。第一部分对设计关键参数及其相互关系进行了灵敏度分析。所研究的参数是透镜的曲率、最大浓度和紧凑度或相关的纵横比。在第二部分中，得出了菲涅耳透镜的聚光比为12.5太阳是满足建筑特性和太阳聚光要求的最佳几何聚光。第三部分对最优菲涅耳两种复合抛物面聚光器的组合设计进行了评价。对光学系统的深入分析为以后的设计者提供了有用的结果。
In this paper an exhaustive study of a stationary wide angle Fresnel lens combined with a moving compound parabolic concentrator to track the Sun during the year is presented. The concentrating optical systems is proposed for building integrated solar applications. In the first section, the sensitivity analysis of design key parameters and its relationships is addressed. The parameters under study are the lens curvature, the maximum concentration and the compactness or the related aspect ratio. In the second section, it is concluded that a concentration ratio of 12.5 suns is the optimum geometric concentration for the Fresnel lens to satisfy both architectural features and solar concentration requirements. In the third section, the combination of the optimum Fresnel two compound parabolic concentrator designs is evaluated. The deep analysis of the optical system presented offers useful results for future designers.
