大型网状天线已经在地球同步轨道(GEO)卫星中得到广泛应用,天线在轨展开后不可避免地会对太阳电池阵产生遮挡.文章分析了大型网状天线对太阳电池阵的遮挡,综合考虑遮挡对太阳电池电路特性、太阳电池阵有效面积和温度的影响,并进行了遮挡损失模拟试验.针对影响分析结果,提出了合理的应对策略,如太阳电池阵被遮挡后功率不足时由蓄电池组参与联合供电,可为电源系统功率设计提供参考.%The large netty antenna has been applied widely on the GEO satellite,and it is inevitable that the antenna shades the solar array when it is deployed in orbit.This paper analyzes the complexion of the shadow,considers influence on the characteristic of the solar cell circuit,the effective area of solar arrays and the temperature shadowed by netty antenna,and completes a simulant test for shadowed loss.Then this paper advances many reasonable solutions aiming at the influences.For example,the battery will supply the satellite for the lack of solar arrays power as a result of the shadow.The analysis can provide a reference for the rationality of the power supply subsystem design.
