摘　　要：针对昌波水电站引水式电站引水距离长、设置上游调压室、蜗壳前进水管直径较大等特点,列出三种水轮发电机组防飞逸保护措施进行分析比选,经综合比选分析后,推荐采用调压室快速闸门作为水轮发电机组的防飞逸保护措施,并详细描述了调压室快速闸门方案。该研究为类似条件的水电站机组防飞逸保护措施方案选择提供参考。As to characteristics of the diversion type of Changbo Hydropower Project,such as the water diversion distance is long,setting up upstream surge chamber,and diameter of water pipe in front of the scroll case is relatively large,three kinds of anti-runaway protection measures for hydroelectric generating units are listed for analysis and comparison.After comprehensive comparison and analysis,this paper recommends the surge chamber rapid-drop gate as the anti-runaway protection measure for hydroelectric generating units,and describes the the scheme in detail.It provides a reference for the selection of anti-runaway protection measures for hydro-turbine generator units under similar conditions.
