两次反射的多镜面太阳能聚光器设计方法探讨

针对抛物面聚光器因受光器阻挡造成的聚光不均匀、加工难度大、不能使用直射光线、占地面积大等缺陷，提出了一种使用两次反射的多平面镜聚光器，给出了单镜面的面积计算方法和太阳能电池表面积接收的光强达到最佳光强的镜面数量计算方法，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，采用这种方法太阳能电池可接收额定光强的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。

A Study for the Designof Double-reflective Multi-mirror Solar Collector

For the block of ray receiver causes the asymmetry focusing,process difficulty,invalidity of straight lights and over-large installing room in paraboloidal mirror,the arithmetic of single plane area as well as the most optimizing number of plane is put forward,and a detective control method is analyzed in this article,so that a double-reflected multi-plane mirror is able to be applied to ensure the solar battery to absorb ray intensity as five times as the rating one,and maximum the output power of the ligh...
