摘　　要：针对使用锂离子蓄电池组的中高轨航天器,提出了一种月影下的太阳电池阵输出功率计算方法,构建了典型的中高轨航天器电源分系统的仿真模型,开展了航天器月影下能量平衡的仿真。采用该方法对某卫星月影下的能量平衡情况进行了计算,并将计算结果与实际遥测数据进行比对,结果表明:该方法可以实现航天器月影下功率平衡的高精度计算。文章提出的方法可以为航天器在轨月影的预测和月影期间蓄电池组的在轨管理提供参考。In this paper, regarding to the medium and high earth orbit spacecraft using lithium-ion batteries,a solar array power calculation method under the lunar eclipse is proposed;a simulation model for typical electrical power system is constructed;and the simulation of the energy balance of the power subsystem are carried out. The method is used to calculate the energy balance of a satellite under lunar eclipse conditions, and the calculation results are compared with the actual telemetry data. The comparison results show that the proposed method can achieve high-precision calculation of power balance under lunar eclipse. The method proposed in this paper can provide reference for the prediction of lunar eclipse and the on orbit management of batteries during the lunar eclipse.
