某西部大型水电站下游调压室稳定断面选择

Selection of stability section of surge chamber in downstream of a large hydropower station in western

某西部水电站工程规模巨大,左右岸两侧各9台机组,每3台机组共用一个规模巨大的下游阻抗式调压室。本文通过对复杂输水系统下游调压室托马临界稳定断面面积的计算方法、控制工况选择及各影响因素分析、计算,最终确定合理的下游调压室稳定断面面积,为其它类似工程提供参考依据。

The left and right rank of large-scale hydropower project separately have 9 units,each 3 units share the large-scale downstream impedance surge chamber.By analyzing the computing method,the working condition selection and other influencing factors of the Thomas critical stable section area for the surge chamber in the downstream of complex water supply systems,the paper determines the rational stable section area of downstream surge chamber,which would provide reference for other similar projects.
