摘　　要：现有关于空间太阳能电站(Space Solar Power Station,SSPS)轨道动力学的研究中,均将其放置于地球静止轨道(Geostationary Orbit,GEO),然而这并非最优的工作轨道。文章提出了一种优于GEO的地球同步拉普拉斯(Geosynchronous Laplace Plane,GLP)轨道。首先,建立了轨道运动模型及影响轨道运动的摄动模型,包括地球非球形引力摄动、日月引力摄动、太阳光压力摄动及微波反冲力摄动;然后,提出了评估空间太阳能电站轨道的3个指标:接收功率、轨道适用性和安全性,并据此分析了GLP轨道相对于GEO的优势。最后,给出了数值仿真算例。结果表明:在发电功率大致相同且满足供电需求的情况下,工作在GLP上的SSPS每年大约能节省用于轨道保持的燃料36 453.4kg。Previous studies on space solar power station （SSPS） have simple assumed geostationary orbit, while it is not the best orbit for SSPS. A new orbit, known as the geosynchronous Laplace plane was put forward, which was superior to geostationary orbit.Firstly, the orbital dynamics and the perturbations which affect the orbital motion were modeled, including Earth＇s nonspherical perturbation, Luni-Solar gravitational perturbation, solar radiation pressure perturbation and microwave three evaluation indexes, including received power, beaming force perturbation. Secondly, orbit applicability and space security, were presented to discuss the advantages of the proposed Laplace orbit rather than the geostationary orbit. Finally, the long-term numerical simulation was provided. And the result shows that the SSPS working in the geosynchronous Laplace orbit can save 36 453.4 kilograms of fuel which is used for orbit maintain comparing to the SSPS working in the geostationary orbit with the same received power and meeting the demand of power supply.
