摘　　要：针对多旋转关节空间太阳能电站提出一种单母线辐射状拓扑,依照设计拓扑给出2种控制方案,并进行对比分析。然后从空间太阳能电站直流输电系统的类电流源特性出发,对单母线辐射状拓扑进行全面的故障分析。依据故障分析设计出限流电抗器与直流接触器配合的保护设备配置方案及母线差动保护与基于高频故障电流保护联合的方案,并仿真验证保护方案故障定位的准确性与快速性。对系统拓扑、运行控制策略、故障状态分析与保护方案配置均进行详细研究分析,可为将来的多旋转关节空间电站的落地提供电力系统层面的设计依据。A single-bus radial topology is proposed for Multi-Rotary joint space solar power station(MR-SSPS),which is a new application method of space power generation,two control schemes are given according to the design topology,and a comparative analysis is carried out.Then,based on the current-like characteristics of the space solar power station’s DC transmission system,a comprehensive failure analysis is performed on the single-bus radial topology.According to the failure analysis,the protection device configuration scheme of the current limiting reactor and the DC contactor is designed,after that the fault location accuracy and rapidity of the protection scheme which is combined with the bus differential protection and the high frequency fault current protection are verified by simulation.This paper has carried out detailed research and analysis from system topology to operation control strategy,failure state analysis and protection scheme configuration,which can provide design reference of power system for the future landing of MR-SSPS.
