Conceptual Study of Inflatable Space-based Solar Power

为了解决现有天基太阳能电站面临的技术难度和成本问题,尽早使其实用化,文章提出了一种新型充气式球形天基太阳能电站概念。概述了新型电站的工作原理、系统构成及功能,重点分析了通过采用球形柔性薄膜太阳能电池和空间充气展开结构材料技术,新型电站无须对日定向,能高效折叠存储升空和大大降低发电模块质量。文章还对新型电站总体设计、折叠展开、在轨刚化、高精度姿态控制及大功率电量存储和传输等关键技术进行了简要论述,可为未来天基太阳能电站的技术发展提供参考。

In order to solve the technical problems and deficiency of space-based solar power （SBSP） and put it into practice as early as possible,an inflatable power concept is proposed in this paper.The system principle and components as well as functions of a novel SBSP are summarized in this paper.The global membrane solar cell and inflatable structure technology which are used in new SBSP are mainly analyzed.In the novel design,the solar cell has high packaging efficiency and lightweight structures and no need of directing to the sun.So the original SBSP plays remarkable effects on system size and cost and technical issues.The key techniques of inflatable SBSP have been analyzed,which are composed of system design,folding and deployment,inorbit rigidification technology in orbit,high-accuracy attitude control,as well as high power electric energy storage and transmission.The concept and scheme of the novel SBSP proposed in this paper can be as a reference for future technical development of SBSP.
