摘要
槽式太阳能热发电系统(槽式系统)符合"大容量-高参数-长周期储热"的国际太阳能热发电技术发展趋势,是世界上商业化最成功的太阳能热发电模式。介绍了槽式系统的原理、特点及分类情况,论述了导热油槽式系统和直接蒸汽发电(DSG)槽式系统的结构特点、发展现状,指出以水为工质的DSG槽式系统是槽式系统的发展方向。
The parabolic trough solar thermal power generation system( parabolic trough system) accords with the requirement of 'large capacity,high parameters and heat accumulation in long period',which is the international development trend of so-lar thermal power generation technology. It is also most successful commercialized solar thermal power generation pattern in the world. The principle,the features and the classification of the parabolic trough system were introduced. The structure features and the development status of the heat conduction oil trough system and the direct steam power generation( DSG) trough system were expounded. It was pointed out that the DSG trough system using water as working medium is the development direction of the parabolic trough system.
