| 摘 要： | 在建立太阳直射辐射计算模型的基础上，分析了聚先反射抛物面镜面在各种跟踪方式下接受到的瞬时太阳直射辐射量，得出了晴天时昆明各月平均日辐照量的变化图。通过对所得数据度曲线图的比较和研究，获得了聚光反射抛物镜面两种较好的组合跟踪方式，效率分别达到双轴跟踪的98．9％和99．34％。可为太阳能申高温跟踪系统的发展和运用提供新的思路。

| Abstract: | Based on the clear-day solar beam radiation model, instantaneous solar beam irradiance received by the parabolic-trough reflection focusing collector with different tracking modes has been calculated and analyzed. Then, graphs of daily average solar beam radiation for every month have been plotted in this paper. By comparing and researching the data and graphs, two kinds of compound tracking modes for the parabolic-trough reflector are obtained. The efficieneies of the correspondingly combined tracking modes can reach 98.9% and 99.34% of the two-axis tracking efficiency, respectively. The results can provide new ideas and methods for applications and developments of solar middle-high temperature tracking systems. |
