摘　　要：针对300 MW机组汽轮机通流改造后的特点,利用改造后的滑压运行试验,得出了机组在调峰范围内的汽轮机滑压运行参考曲线,选择合适的阀门开启顺序,对典型运行工况的阀门内部流场进行数值模拟和分析,并对阀门管理方式给出积极建议。According to the characteristics of the 300 MW steam turbine after the flow path retrofit,and based on the reformed sliding pressure operation tests,the steam turbine sliding pressure operation reference curves were derived in range of peak regulation.The appropriate valve opening sequence was selected,and the internal flow field of the valve under typical operating conditions was numerically simulated and analyzed,and the positive suggestions for valve management were proposed.
