基于平板玻璃镜反射聚光获得等光强分布的方法,提出了折平板反射聚光太阳能系统的设计方案。推导了平行光聚光公式,可在给定接收截面宽度、倾角和安装高度时,给出一定聚光比所需的反射板数量、宽度、倾角及坐标位置;建立了CCD法测量能流密度分布的测试平台以及聚光光伏实验装置,并对折平板聚光系统进行了实验研究。结果表明,折平板玻璃镜聚光系统可以得到较为均匀的辐射能流密度,并且系统的发电效率也较高。
Based on the method of obtaining the equal light intensity distribution by the reflection of the flat glass mirror, the design scheme of the flat-plate reflecting concentrating solar system is proposed. The formula of parallel light condensing is deduced. The number, width, inclination and coordinate of the reflecting plate are obtained when the width, inclination and installation height of the receiving section are given. Distributed test platform and condenser photovoltaic experimental device, and the experimental research on the folding plate condenser system. The results show that the flat glass mirror condenser system can obtain a more uniform radiation energy flux density, and the system has higher power generation efficiency.
