概述了太阳能热发电技术的发展状况，介绍了用于太阳能热发电的5种聚光系统，包括槽式、碟式、塔式、线性菲涅耳式以及地面接收式。详细阐述了这些聚光系统的光学结构、聚光原理以及聚光器件的设计方法和制作工艺，指出了不同聚光系统在聚光过程中的优缺点。文中的讨论可为太阳能热发电聚光系统的设计提供参考。

The development of solar thermal power generation technology is introduced. Five kinds of concentration systems, including parabolic trough concentrators, solar dishes, solar towers, lineal Fresnel concentrators and beam down concentrators, are presented. The optical structures, concentration principles, design methods and production process for the solar concentrators are described and the advantages and disadvantages of the different optical systems in the solar thermal power plant are commented. The discussion in this paper can provide references for design of solar thermal power plant concentration systems.
