太阳能塔式光热镜场光学效率计算方法

The calculation method of the optical efficiency of the solar power tower heliostat field

太阳能光热电站中,镜场作为热量的聚焦装置,其聚焦太阳能的能力需要以镜场性能来衡量,其中镜场阴影挡光效率和截断效率是镜场光学效率计算过程中的难点,理论模型较为复杂。采用几何光学算法分析阐述镜场性能的计算理论模型。

In the solar thermal power generation project,as the device for focusing the sunlight to the receiver,the ability of the solar field needs to be measured by solar field performance.The shading and blocking efficiency and the spillage efficiency which belong to the solar field performance is difficult in the process of optical efficiency calculation,and the theoretical model is complex.In this paper,the geometrical optics algorithm is used to analyze the theoretical model of the solar field performance.
