针对电推进系统高功率需求,以整星能源的高效利用为目标,以电推力器的复杂工程参数和整星能源为约束,提出基于太阳电池阵和蓄电池组联合供电的静止轨道卫星电推进在轨工作策略,定量分析不同电推进类型、太阳翼构型、电源系统配置等对工作策略的影响,得到复杂工程约束条件下的南北位保、东西位保和角动量卸载控制周期的优选方法.仿真算例表明,在留有工程设计余量的情况下,根据该方法优选得到的电推进工作策略可以满足电推进系统的使用要求和整星能源平衡要求,与采用增大太阳帆板面积的方法相比,可避免卫星平台承重能力降低(约60 kg),并提高整星能源利用率.
In view of the high power demand of electric propulsion system and the goal of efficient use of the entire star energy, the paper proposes the electric propulsion of the geostationary orbit satellite based on the complex engineering parameters of the electric thruster and the whole-star energy. Rail operation strategy to quantitatively analyze the influence of different types of electric propulsion, solar wing configuration and power supply system configuration on work strategy, and obtain the preferred method for controlling the unloading control cycle of north-south and east-west BOP under complicated engineering constraints. The simulation results show that with the engineering design allowance, the optimal electric propulsion strategy can meet the requirements of the electric propulsion system and the energy balance of the whole star, and the method of increasing the area of solar panels Compared to the satellite platform can be reduced to reduce the load-bearing capacity (about 60 kg), and improve overall energy efficiency.
