Review of concentration system in solar thermal power plant

The development of solar thermal power generation technology is introduced.Five kinds of concentration systems,including parabolic trough concentrators,solar dishes,solar towers,lineal Fresnel concentrators and beam down concentrators,are presented.The optical structures,concentration principles,design methods and production process for the solar concentrators are described and the advantages and disadvantages of the different optical systems in the solar thermal power plant are commented.The discussion in this paper can provide references for design of solar thermal power plant concentration systems.
