摘　　要：为改善燃气轮机热电联供变工况运行的经济性,采用回注蒸汽燃气轮机循环有一定的优越性。为此,以10MW燃气轮机组为例进行技术经济分析。具体分析了燃气轮机在不同的负荷规律下的变工况情况,以发电成本为优化目标,通过优化上网电价来提高经济性。计算结果表明:燃气轮机热电联供系统采用注蒸汽来提高机组的经济性是可行的。STIG (steaminjected gas turbine) loop has some superiority in improving the economics of cogeneration gas turbines in variable parameter operation.In this paper,a technoeconomic analysis is made taking a 10 MW gas turbine unit for example.The gas turbine conditions under different load laws are analyzed,and with power generating costs as the optimization target,the economics can be improved by optimizing the sales price to grid.The calculation results show that it is feasible to improve the units economics with STIG loop.
