太阳能热发电系统的研究现状综述

介绍塔式、槽式、碟式、太阳能热气流和太阳能池热发电等5种主要类型的太阳能热发电系统的工作原理及研究现状,并对各类太阳能热发电技术的优缺点进行了比较。结果表明,塔式太阳能热发电系统聚光比高,系统容量大、效率高,但费用昂贵;槽式太阳能热发电系统结构简单,但聚光比小,系统工作温度较低;碟式太阳能热发电系统聚光比大,系统效率高,结构紧凑,安装方便,但其核心部件斯特林发动机技术难度较大;太阳能热气流发电、太阳能池热发电及向下反射式太阳能热发电等在技术上各有优势。

STATUS QUO IN RESEARCH OF SOLAR ENERGY THERMAL POWER GENERATION SYSTEM

The working principle and status quo of research for five main kinds of solar energy thermal power generation system,namely tower type,trouph type,dish type,solar energy hot gas flow type,and solar energy pool,have been presented.Comparison of advantages and disadvantages for above-mentioned solar energy thermal power generation systems shows that as in the following:the tower type system has high light concentration ratio,large capacity of system,and high efficiency,but expenses being very high;the trough type system has simple structure,but the light concentration ratio being small,and the working temperature in the system being lower;the dish type system has large light concentration ratio,high system efficiency,compact structure,and convenience in installation,but large difficulty in techique of its key part i.e.the Sterlin engine;the solar energy hot gas flow power generation and the solar energy pool,as well as the downward reflecting type solar energy thermal power generation etc.,each has its own superiority in technical aspects.
