摘　　要：介绍了长江三峡电站700 MW水轮发电机组快速闸门液压系统的动作原理,分析了闸门快闭过程中可能出现门体突然停止运动的风险,提出了通过优化液压系统回路解决此风险的方法。Working principles of the hydraulic system for fast operating gates of the 700 MW hydropower units in Three Gorges hydropower station is introduced. It is found that the gates suffer a risk of sudden stop during the quick closing process. Accordingly,an optimization scheme on the quick closing circuit in the hydraulic system is proposed to avoid such risk.
