掌握太阳能热发电系统的发电模式、性能特点,对推进我国太阳能热发电系统的发展有十分重要的意义,对太阳能热发电系统各种发电模式的分类、工作原理、主要性能参数以及系统的关键研究和发展趋势进行了介绍。结果表明:槽式、塔式、碟式3种太阳能发电系统中槽式和塔式系统实现了商业化,碟式处在示范阶段,并且未来槽式太阳能发电成本在经济上有可能与常规热力发电相竞争;碟式系统净发电效率高,在3类系统中位居首位;塔式系统发电单位容量投资大且降低造价较难。
It has important significance to grasp the generating mode and performance of solar thermal electric power generation system for development of the system. There are three generation modes of solar thermal electric power generation system: trough system; tower system and dish system, and their classification , working principle, main performance parameters, key techniques and development trends were introduced respectively. At the present time, the trough system and tower system have been commercialized in large scale, and the dish system is in demonstration stage yet. The trough system will can compete with conventional thermal power generation in generation cost. The dish system has highest net generation efficiency in the three types. The tower system has higher construction cost for unit capacity and which is difficult to be reduced.
