摘要
塔式太阳能热发电系统具有聚光比大、投射到塔顶吸热器上的平均热流密度高、工作温度高、电站规模大和年度发电效率高等特点,提高效率和降低成本的潜力较大。文章阐述了塔式太阳能热发电技术的工作原理和系统组成;介绍和分析了国内外已建成的塔式太阳能电站;指出了塔式太阳能热发电技术的发展现状、技术难点和未来发展方向;探讨了我国规模化发展塔式太阳能热发电技术须解决的问题。
Solar power tower system has many advantages such as high concentration ratio, high average heat flux density projected onto the collector, high working temperature, availability of large-scale plants and high annual power generation efficiency, etc. Furthermore, solar power tower system also has a great potential of efficiency improvement and cost reduction. In this paper, solar thermal power generation technology working principles and system structure are introduced and analyzed, current situations, technical difficulties and future development direction of the technology are pointed as well. At the same time, scale development problems that need to be solved in China are discussed properly.
