摘　　要：集热子系统是塔式太阳能热发电不同于火力发电的主要部分。定日镜和吸热器是集热子系统的关键部件。以八达岭1 MW塔式太阳能热发电系统为研究对象,以热力学第一、第二定律为理论基础,结合塔式太阳能热发电系统模型,采用能量系统的白箱模型分析方法对塔式太阳能热发电集热子系統进行火用分析。对系统用能状况作出合理评价,找出系统用能的"薄弱环节",为系统节能提供依据。The thermal collect subsystem of a tower solar power system is the main part which is different from a thermal power system. Heliostat and absorber are the key components of the thermal collect subsystem. Based on the Badaling 1 MW tower solar thermal power generation system, and the first law of thermodynamics and the second law of thermodynamics,using the model of tower solar power system, the Exergy analysis in white model of the energy system is conducted. In order to offer guidance for energy saving of solar power system,the energy usage is evaluated reasonably and the vulnerable spot is figured out.
