摘要
通过太阳能与燃煤机组混合发电系统的分析研究,以槽式太阳能集热器与燃煤机组集成为基础,采用以工质直接吸收太阳能热的方式,考虑工质不同的引出和引入系统的部位,提出了三种不同的系统集成方式。对三种系统集成方式进行模拟,根据模拟结果对系统不同性能指标进行了分析,选出了其中最优的集成方式。同时对该系统集成方式进行了技术经济分析,结果表明其太阳能发电部分的LEC成本为0.539元/k W·h,低于单纯的太阳能热发电成本,与风力发电和秸秆发电等可再生资源发电技术相当。
Analyzed the parabolic trough solar field/coal -fired hybrid thermal power system. By way of direct absorption of solar energy to heat the working fluid, taking into account the working fluid extraction and introduction of different parts of the system, this paper proposed three different ways of integrated systems. Simulated the three kinds of system integration methods. According to the simulation results, the different performance indexes of the system was analyzed, and selected the optimal integration method. At the same time, analyzed the technical and economic of the system. The results show that the LEC cost of the part of solar thermal power in hybrid system is 0. 539 yuan/ kW ~ h, which is lower than solar only thermal power systems and is equivalent to the LEC cost of wind power generation and straw power generation technology.
