摘　　要：根据多曲面槽式聚光器的聚光性能,提出一种新的应用于光伏发电系统的聚光器结构设计方法,建立详细完整的三维模型,采用光学追迹、几何光学分析等方法对模型中的光学性能进行仿真计算研究。通过追迹模拟,直观地再现了聚焦光线的分布、焦斑宽度,并对其几何光学效率、聚焦中心偏移量随入射偏角的变化关系进行了计算和分析。结果表明,当入射偏角不大于2.8°时,此聚光系统的几何光学效率为99.81%,聚焦中心偏移量随入射偏角呈线性变化。所建立的模型可为聚光光伏发电系统的光学效率研究提供参考。Based on the concentration performance of multiple chamber trough solar concentrators, a novel structure design method of concentrator applied in photovoltaic power system was presented. A 3D model supported with optical analysis software was used to simulate and calculate optical performance of the model with methods of optical tracking and geometrical optics analysis. Through tracing simulation, the distribution of concentration light and the width of the focal spot could be directly observed. According to the optical performance of the model, the relation of geometrical optics efficiency, and center offset with deflective incidence angle were calculated and analyzed. The results indicate that the geometrical optics efficiency is 99.81%, when deflective incidence angle is not bigger than 2.8° , and center offset is in a linear correlation with deflective incidence angle. The model could serve as a reference for optical efficiency research of concentrating photovoltaic power system.
