摘要
为避免传统聚光式光伏系统中反射镜面的遮挡,介绍等光强非等截面线性菲涅尔反射镜(LFR)聚光光伏系统的设计原理,并对系统的几何设计进行介绍。建立该系统反射聚光器的光学分析模型,利用蒙特卡罗光线追迹方法对该聚光器的聚光效果和性能进行模拟和分析,结果表明该系统具有良好的聚光均匀性。对等光强非等截面LFR光伏系统参数分析表明,系统几何聚光比随镜场宽度的增大而增加,而镜场利用率则随镜场宽度的增大存在最优值。对系统跟踪误差进行计算,结果表明当反射器追迹光线偏差1°时,聚光器的效果降低37.5%。
In order to avoid the shading effect of the mirrors in the conventional concentrated photovoltaic system,this paper introduces the design principle of uniform-light-intensity non-equal-width linear Fresnel reflector(LFR)photovoltaic system as well as the geometrical design of the system. The optical analysis model of the reflective concentrator is established and the Monte Carlo ray tracing method is applied to simulate and analyze the solar concentration performance.And the results show that the system has good uniformity of solar collection. The parameters analysis results of LFR photovoltaic system show that the geometric concentrating ratio of the system increases with the increase of the width of the mirror field,while the utilization ratio of the mirror field exists an optimal value with the mirror field width increasing. The tracking error of the system is calculated and the results show that the optical efficiency of the LFR concentrator is reduced by 37.5% when the tracking deviation angle is 1°.
