摘要
针对抛物面聚光器因受光器阻挡造成的聚光不均匀、不能使用直射光线、占地面积大等缺陷,提出一种采用球面镜折射的低倍太阳能聚光器,给出了聚光比和聚光器体积的计算方法,对单元聚光器相互间的遮光问题进行了讨论,并分析了太阳能聚光器的跟踪控制方式。仿真试验结果表明,采用这种方法单元聚光器在互不遮光条件下可接收额定光强的5倍左右太阳能辐射,可以在太阳能电池标准配置下大大提高光伏系统的输出功率。
Aiming at the disadvantage of ray receiver, which is caused by asymmetry focusing, invalidity of straight lights and over-large installing room in parabolic reflector, a solar condenser with the use of the spherical mirror＇s refrac- tion is proposed. The calculation of the concentration ratio and the volume of the condenser are put forward, the condenser on the unit inter-shading problem is discussed, and the tracking control mode of the solar condenser is analyzed in this paper. The experimental result of simulation shows that this spherical refraction solar condenser could be applied to ensure the condenser unit to absorb ray intensity as five times as the ratio one under the conditions of mutual non-shading.
