空间太阳能发电卫星的几个理论与关键技术问题

The main aspects of the theory and key technologies about Space Solar Power Satellite

本文较为系统地阐述了发展空间太阳能发电卫星(space solar power satellite, SSPS)的几个问题.首先,论述了发展SSPS对世界人类从根本上解决能源危机,尤其是对我国生存与发展的极端重要性.其次,对聚光与非聚光两大类空间太阳能发电卫星的几个典型设计方案,从功质比(即单位质量所产生的电能)指标、工程实现、可靠性等方面,分析了它们的优缺点.再者,对作者团队2014年提出的SSPS-OMEGA方案的近期研究进展作了较为详细的讨论.最后,就本领域近期进展与未来需注意的几个理论与技术问题,提出了相应的观点.

This paper presents several problems about development of Space Solar Power Satellite （SSPS） systematically. Firstly, the importance of developing SSPS to solve the energy crisis of the world is discussed. Secondly, two main categories of SSPS, non-focusing and focusing concepts, are described with the advantages and disadvantages, such as the specific power to mass ratio （energy produced by unit mass）, engineering implementation, reliability and so on. Thirdly, recent achievement of SSPS-OMEGA concept proposed by author＇s team in 2014 is provided. Finally, future development on SSPS is discussed.
