摘　　要：提出一种大型汽轮机组单顺阀配汽方式经济性分析方法,结合某国产600MW汽轮机组不同负荷下单阀与顺序阀对比试验,对大型汽轮机组不同配汽方式下运行经济性进行分析和比较。试验结果表明,汽轮机组在顺序阀方式下的运行经济性要高于单阀方式,且运行负荷越低,顺序阀方式的节能效果越明显。A analysis method of operating economy of the large steam turbine unit in different governing modes was proposed, and the experimental research on operating economy of the large steam turbine unit in different governing modes was performed based on test of domestic made 600MW turbine operation under full arc admission and partial arc admission mode. The result of test indicated that the operating economy of the large steam turbine unit under partial arc admission mode was higher than it under full arc admission mode, and the lower load was, the more obvious energy - saving was.
