摘　　要：在以往研究基础上对600MW喷嘴配汽方式汽轮机调节阀特性做进一步研究。针对调节阀特性,分别从热力特性与流量特性两方面,通过数值计算法与仿真试验法探讨调节级压比、反动度及蒸汽流量随调节阀动作的变化规律,为喷嘴配汽方式汽轮机组运行优化研究提供了理论指导。Based on previous research on valve characteristics, this paper had a further study with a 600MW nozzle governing steam turbine. The change rule of governing stage pressure ratio, reaction degree and steam mass flow had been analyzed from two aspects of themal characteristics and flow characteristics by the method of numerical calculation combined with simulation test, which provide theoretical guidance for the research of operation mode optimization on nozzle governing steam turbine unit.
