| 摘 要： | 针对华能玉环电厂1000MW机组正常运行时主汽调门处于35%左右开度的问题,分析了主汽调门不能全开的原因,以及此种现象对机组经济性和安全性的影响。主汽调门在机组正常运行时不能处于全开位置的原因是机组逻辑中设定的主汽压力曲线与汽轮机实际性能不相匹配。文章分析了汽轮机主汽调门运行方式的改进的方案,供已投运的存在类似问题的机组和拟建机组做改进和设计参考。

| Abstract: | During the normal operation of 1 000 MW generating unit in Huaneng Yuhuan power plant,the main steam governing valve couldn't be fully opened,being at about 35% opening,the paper analyzed the cause of this problem,as well as the impact of this phenomena on the economics and safety of the unit.It was found that,the cause of this problem was,the main steam pressure curve set in the logic of unit and the actual performance of steam turbine were not matched each other.The paper analyzed the improvement scheme o... |
