摘　　要：全电推进卫星平台能够大幅度降低卫星平台的推进剂需求量,并带来包括减轻卫星发射重量、提高卫星有效载荷能力、延长卫星服役寿命等方面的经济效益.通过调研全电推进卫星平台的进展情况,梳理了全电推进卫星平台对电推进的任务需求,设计了全电推进系统方案及应用模式,经过分析计算,卫星发射重量在2 000 ～3 000 kg 之间,在半年之内完成卫星轨道转移,需要单台推力器推力达到200～300 mN,选择适当的轨道策略,全电推进系统是可以满足任务需求的.All electric propulsion satellite platform can reduce the demand for propellant,it will Bring economic benefitson reducing the satellite launch weight,improving the ability of the satellite payload,prolonging the service life ofsatellite. This paper studied the progress of all electric propulsion satellite platform,combed the requirements of electricpropulsion’ s mission for all electric propulsion satellite platform,designed the scheme of electric propulsion system andapplication mode. By analyzing and calculating,if the satellite launch weight between 2 000～3 000 kg,and completed orbittransfer within half a year,the single thruster need output thrust between 200～300 mN. So selected the appropriatestrategy,all electric propulsion system can meet the demand of the mission.
