摘要
卫星太阳电池阵的在轨特性主要受太阳入射角、地日距离因子、温度、星体遮挡、地球反照和衰减因素的影响。文章利用某太阳同步轨道卫星在轨数据,分析得出太阳电池阵输出功率的变化规律,并利用归一化处理方法,得出地球反照、星体遮挡、衰减因素对太阳电池阵输出功率的影响规律。文章的研究成果也适用于其他太阳同步轨道卫星,可为后续同类太阳电池阵的优化设计提供参考。
The main factors which affect the performance of Si solar array for satellite in sun syn- chronous orbit include the incidence angle of the sun, the earth-sun distance factor, the tempera- ture of the solar array,the shadow of satellite body, the earth radiation,and the attenuation fac- tor. This article uses the data of a sun synchronous satellite in orbit to analyse the rules of the Si solar array output power to study the influence of the shadow of satellite body, the earth radia- tion, and the attenuation factor. The data provided by this article can be used for the design of the same sort of solar array on sun synchronous orbit satellites. Furthermore, it provides some refer- ence for optimizing design of the solar array.
