空间太阳电站的发展前景评估

Future Prospect of Space Power Satellite

首先回顾了NASA的空间太阳电站 1 979SPS基准系统方案及其产生与搁置的背景 ,强调了1 995～ 1 997年新一轮论证中所提方案的高度模块化特点 ,这一特点使空间太阳电站的技术可行性大为增加。其次介绍了空间电站研究的工作分解结构和所需的关键技术。最后从全球对电能的需求、有关国家的态度、关键技术的进展等几个方面 。

In this paper the architecture of the NASA 1979 SPS Reference system and the background for its formation and deadlock are firstly r eviewed with emphasis on the characteristics of modularization proposed by the 1 995～1997 fresh look on SPS(Solar Power Satellite), which have greatly increased the technical feasibility of SPS. Secondly, the work breakthrough structure of the architecture study and the critical technologies required for SPS are descri bed. And finally, two different assessments on the future prospect of SPS in ter ms of global requirements of eletric power, attitude of the related nations and possible progress of the critical technologies are summarized.
