摘要：

针对多旋转关节空间太阳能电站(Space Solar Power Station, SSPS)，提出一种环形拓扑的电力系统架构。基于功率分层准则对SSPS电力拓扑架构进行设计，提出U1~U7共7个层级、母线电压5000V、功率等级为MW的太阳能电站电力系统。针对分层架构中多太阳电池阵子阵并联(U6层)，提出分层功率平衡统一控制策略，对MPPT控制、MPPT控制+稳定直流母线电压混合控制、MPPT算法+下垂稳定直流母线电压混合控制三种控制方法开展仿真分析。结果表明，提出的基于虚拟阻抗的下垂控制策略可以有效调节、分配功率，解决了空间发电站母线电压无法稳定的问题。

Abstract:

 A surround space solar power station (SSPS) power topology with the hierarchical power design method is proposed. The topology is suitable for the SSPS with multi-rotary joints. The unified power management technology for the power balance control system is put forward in the paper. The maximum power point tracking (MPPT) control, MPPT control plus stable DC bus voltage control, and MPPT algorithm plus stable DC bus voltage drop control methods are simulated. The simulation results show that the drop control strategy based on virtual impedance is better.

Key words:  Space solar power station (SSPS), Unified dispatching, Power management, Voltage drop control, Virtual impedance
