对我国发展太阳能热发电的一点看法

太阳能热发电是大规模开发利用太阳能的一个重要技术途径。由于关键技术有待重大突破,目前国外塔式、槽式、碟式系统都还面临着投资大、成本高的问题。本文分析了塔式、槽式、碟式现行三种技术路线在我国推广应用的技术难点,提出了一个新型分立式太阳能热发电技术路线。这项新技术建立在太阳聚光跟踪理论突破的基础之上,不仅具有完全自主知识产权,而且比国外现行的热发电技术更为经济高效。

Some Opinions on Developing Solar Thermal Power in Our Country

Solar thermal power generation is an important technology to utilize solar energy in large scale. As it still desires the significant breakthroughs, the traditional technologies that are Central Tower System, Parabolic Trough System and Dish-Stirling System, are facing great challenges in application and promotion due to the high cost of installation and generation. The obstacles and difficulties of the traditional technologies in China are respectively analyzed in this paper. Besides, the paper also introduces a new solar thermal technology named as Target -fixed Thermal Power System with Non-imaging Heliostat. Based on the breakthroughs of the solar focusing and tracking theory, this new technology is not only with self-owned intellectual property right, but also has cost-effectiveness advantages over the traditional ones.
