Design and Analysis of Anti-occlusion for Solar Array of Inclined LEO Satellite
低轨倾斜轨道卫星轨道面光照角周期变化,太阳电池阵受照情况复杂,其输出电流呈现波动.为此,文章分析卫星各种工况下的本体遮挡面积,结合太阳电池阵遮挡工作特性分析及阴影遮挡试验结果,开展太阳电池阵防阴影遮挡设计,并采用投影法进行卫星本体遮挡影响分析.结果表明:卫星本体遮挡时,电流损失预计值与在轨遥测电流损失值基本一致,分析误差小于 2%.上述分析结果可为卫星复杂遮挡工况下电源系统能量平衡设计提供参考.
The periodic variation of Beta angle of inclined LEO(low earth orbit)satellite results in complex illumination of the solar array and fluctuations in the output current.The obstruction ar-ea of the main body under all working conditions is analyzed based on the solar array's working characteristics and shading test results.The design of the solar array to minimize shading influ-ence is conducted,and the projection method is employed to analyze the impact of body shading.The results indicate that the obstruction current loss aligns with the telemetry current loss,with an analysis error less than 2%.These findings can serve as a reference for the energy balance de-sign of power systems under complex shading conditions.
