Solar Energy-based Thermal Power Generation Technologies and their Systems

我国对大规模太阳能热发电技术的研究仍处于起步阶段,而国外则已进行了多年的研究。本文介绍了各类太阳能热发电技术及其系统,总结了国内外一些学者的研究成果,比较了各类太阳能热发电技术的优缺点。塔式和槽式技术最适用于大规模太阳能热系统。碟式太阳能热发电装置功率较小,适用于分布式能源系统。其它太阳能热发电技术仍处在试验研究阶段。今后的研究重点主要是塔式太阳能热发电系统的系统集成技术和槽式真空吸热管技术。

The research on large-scale solar energy-based thermal power generation technologies in China is still in its infancy but in foreign countries it has been going on for many years.The authors have described the technologies in question and their systems,summarizing the research achievements of some Chinese and foreign academics and comparing their advantages and disadvantages.The tower and trough type technologies are most suitable for large-scale solar energy thermal systems.Due to its relatively small power output,the dish type is applicable for distributed energy source systems.Other systems are still in their experimental and research stage.Among the above,the integrated technology of the tower type and the vacuum heat absorption tube technology of the trough type will be the focus for future research.
