摘　　要：对于国际上典型的空间太阳能电站概念方案进行了分析,在此基础上提出了一种新的概念方案——多旋转关节空间太阳能电站,并给出总体构型和主要分系统初步方案设计结果。该方案采用多个相互独立的太阳电池子阵代替了传统的整体式太阳电池阵,以多个中等功率的导电旋转关节替代传统的极高功率的旋转关节,不仅解决了传统空间太阳能电站方案中的极大功率导电旋转关节技术难题,还可以避免导电关节的单点失效问题,模块化的设计也使得系统的组装和构建更加可行。An innovative Multi-Rotary joints SPS concept （MR-SPS） is proposed and the primary scheme of the concept is designed. For the concept, the huge solar array is substituted by many separate small solar sub-arrays and the high power rotary joint is replaced by many middle power rotary joints, thus decreasing the technical difficulty of extremely high power rotary joint greatly. At the same time, the single point failure problem existing in the traditional SPS concept also is solved and the modular design makes the system be assembled more easily.
