空间太阳能电站的发展及关键技术综述

Development and key technologies of space solar power station

寻找新型清洁的可再生能源已经成为当今人类发展亟待解决的问题,地面太阳能技术是发展最快的可再生能源技术之一。与现有地面太阳能技术相比,空间太阳能电站具有全天时/全天候发电、效率高、零排放等优点。多年来,许多国家和组织的科学家们一直致力于通过不同的途径证明太阳能发电卫星这一方案的可行性,已经取得一些成就,但仍然面临成本、技术等多方面的严峻挑战。从太阳能发电卫星技术的研发背景、研究现状以及关键技术等方面阐述相关内容,分析建立空间太阳能电站的可行性,为未来空间太阳能电站发展战略提供参考。

Looking for a new clean and renewable energy has become a problem which must be solved in the process of human development. Ground solar technology is one of the fastest growing renewable energy technologies. Compared with the existing ground solar technology, the most obvious feature of the space solar power is full-time/all-day power generation, high efficiency, zero emission. Over the years, many countries and organizations has been committed to prove the feasibility of this scheme through many different ways, and has made some achievements. However, solar power satellite also faces the challenge of cost, technology and other aspects. In order to promote the development of related technologies for space solar power stations in China, we comprehensively expounded relevant contents from the R&D background, research status, and key technologies of solar power satellite technology. We also summarized the feasibility of establishing a space solar power station to provide support for the future development strategy of space solar power stations.
