摘　　要：针对卫星电源系统在轨输出功率受轨道及光照条件的影响,提出了一种可实时计算在轨输出特性的通用化卫星电源系统数字仿真模型。首先,分别建立了电源系统各组成模块的数字仿真模型;其次,分析了在轨卫星的轨道周期、进出影时长、太阳光照角、工作温度和光照强度等变化因素,作为外部动态参数输入仿真模型,得到实时在轨输出结果;最后,将所提模型和传统模型的仿真结果分别与实际在轨遥测数据进行比对,验证了所提仿真模型的准确性。In response to the influence of orbit and illumination conditions on the on-orbit output power of satellite power system,a generalized digital simulation model of the universal power system is proposed to calculate the in-orbit output characteristics in real time.Firstly,the digital simulation models of each component module of the power system are established respectively.Secondly,the changing factors of orbital period,in-and-out shadow duration,solar illumination angle,operating temperature and illumination intensity of the orbiting satellite are analyzed,and the real-time in-orbit output results are input into the simulation model as external dynamic parameters,to obtain the real-time in-orbit output results.Finally,the simulation results are compared with the actual in-orbit telemetry data to verify the accuracy of the simulation model in this paper.
