摘要: 太阳能热互补燃气蒸汽联合循环发电(ISCC)技术是一种高效、清洁的发电方式,既可降低太阳能的发电成本,又能减小联合循环的燃料消耗。以导热油为导热工质、太阳能直接发生系统(DSG)、以压缩空气为导热工质的3种槽式ISCC系统作为研究对象,从典型天性能、年性能及经济性能3个方面对3种ISCC系统进行对比分析。结果表明:与DSG集成的ISCC系统的热力性能及经济性能均最优。

Abstract: Integrated solar combined cycle (ISCC) power generation system has been proved to be a high efficient and clean way for power generation, which can reduce not only the cost of solar power generation, but also the fuel consumption of gas steam combined cycle system. In this paper, three kinds of trough ISCC systems with different heat transfer mediums including the heat conducting oil, direct steam generation (DSG) and compressed air are investigated and compared in depth. The performance differences between them are analyzed, especially in the aspects of typical day performance, year performance and economic performance. From the results the ISCC system integrated with DSG has demonstrated the best thermal and economic performance among them.
