摘　　要：以多旋转关节空间太阳能电站(SPS)为应用系统,介绍了MW级SPS微波能量传输系统顶层设计参数。针对微波功率源相位误差对微波能量传输的影响问题,建立了分析模型,提出分析方法,并从波束收集效率下降容限的角度,用一维模型对百米量级能量发射阵列进行了分析,据此给出了对大规模微波源相位误差的要求,为MW级SPS的微波能量传输系统设计提供指导。Based on nmlti-rotary joints solar power satellit（MR-SPS） , system design parameters are introduced in this paper of microwave power transmission of a mega-watt（MW） level SPS. To investigate the problem that how microwave power sources phase errors affect microwave power transmission,an analysis model is set up and the analysis method is put for ward. Then h＇om the point of view of beam collection efficiency degradation tolerance, one-dimension model is employed to analyze a power transmitting array with aperture of a few hundred meters. Phase error requirement is presented accordingly for the large scale microwave power sources, which would be deemed as design criteria for microwave power transmission system of MW-level SPS.
