摘　　要：为解决当前汽轮机阀门在单阀方式下会产生负荷自发扰动,而在顺序阀方式下负荷会产生突变的问题,选用国产300 MW亚临界机组为研究对象,分别开展了顺序阀方式下和单阀方式下阀门流量特性的优化计算与试验,提出阀门流量特性优化方案。试验结果表明,机组控制的稳定性明显改善,优化效果达到设计要求。In order to solve the problems that the steam turbine valve causes generator unit load jump under the single-valve mode,and the generator unit load causes a sudden change under the sequence-valve mode,the domestic 300 MW subcritical generator unit is selected as the research object,based on which the optimization calculation and test of valve flow characteristics under the sequence-valve mode and the single-valve mode are carried out respectively.The optimization scheme of valve flow characteristics is proposed.The test results show that the stability of the generator unit control is significantly improved,and the optimization effect meets the design requirements.
