模块化多旋转关节空间太阳能电站方案设计

文章基于多旋转关节空间太阳能电站（MR-SPS）方案，以降低远距离高压电力传输技术难度为核心，提出一种更新的模块化多旋转关节空间太阳能电站概念。该方案在分布式太阳电池分阵和多导电旋转关节基础上，对于微波发射天线阵也进行了模块化设计和分布式布局，实现了太阳电池分阵和微波发射天线分阵的一一对应，形成多个独立的太阳能发电与能量传输模块，通过模块的扩展实现整个空间太阳能电站。该方案大幅简化了空间电力传输与管理的复杂性和在轨组装的难度。同时各个模块完全独立，组装后即可单独工作，也提高了系统的可靠性。

Concept design on modular multi-rotary joints solar power satellite

Based on the Multi-rotation joints solar power satellite (MR-SPS) concept, an updated modular MR-SPS concept is presented to decrease the difficulty of long-distance high-voltage power transmission. Based on the distributed solar cell sub-arrays and conductive rotary joints, the transmission antenna array is designed by modularization and distributed layout to realize one-to-one correspondence between solar cell sub-array and microwave transmission antenna sub-array. Each solar cell sub-array and corresponding microwave transmission antenna sub-array are combined to form an independent solar power generation and energy transmission module. The extension of multiple modules forms the whole SPS. The design scheme simplifies the complexity of power transmission and assembly in space greatly. At the same time, each module is independent and can operate solely to improve the reliability of the whole system.
