摘要
文章对空间站太阳能热动力系统和光伏电池系统进行了分析比较 ,重点介绍了闭式Brayton循环的组成及其工作原理。太阳光伏电池技术成熟 ,有应用经验 ,但其效率低 ,面积大 ,后期运行费用很高。太阳能热动力系统具有高效率 ,紧凑和可靠性好等优点 ,长期运行的费用低 ,是一种先进的太阳能电源方案 。
Solar dynamic power system and photovoltaic cell for space station are analyzed and compared in this paper. Constitution and working principle of closed Brayton cycle are emphatically introduced. Solar photovoltaic cell is technically mature and stands tests. But it is large, low in efficiency and costly in anaphase operation, while solar dynamic power system is compact, high in efficiency and comparatively cheap in a long run. It can be seen that solar dynamic power system is an advanced project of power supply in space station, among which closed Brayton cycle is likely to be technically realized in the near future.
