Abstract

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.

Key words: solar energy, combined cycle, typical day performance, annual performance, economic performance
