摘要
用电算方法复核计算了二滩水电站 550MW水轮发电机组的蜗壳压力升值、机组转速上升值和尾水管进口真空值 ,并提出了导叶接力器的优化关闭规律 ,同时还提出了抑制和避免调压室涌浪不利叠加的运行方式。
The scroll case pressure increase,unit rotation speed rise and draft tube intake vaccum are checking estimated for 550MW turbine generator units of Ertan Hydroelectric Plant by computer method,the optimized closing law of guide vane servo mechanism is advanced and the operation method for restraining and avoiding undesirable superposition of chamber surge presented.
