阿尔塔什水利枢纽水电站引水系统过渡过程分析

Analysis on Transition Process of Diversion System in Hydropower Station of Aertash Hydro Project

阿尔塔什水利枢纽水电站引水系统长度较长。通过调压室过渡过程计算优化调压室的尺寸,既而通过对导叶关闭规律进行比较计算,确定机组最短关闭时间;再通过小波动过渡过程计算分析系统的小波动过程是否稳定;通过水力干扰计算判断被干扰机组的水头、流量、效率、机组轴力矩变化是否超过允许范围。研究结论为电站引水系统设计提供依据。

As we know,the diversion system in the hydropower station of Aertash Hydro Project is long.Through calculating the transition process of surge chamber,the size of the surge chamber is optimized;Through comparing and calculating the rules of guide vane,the shortest closing time is confirmed;Through calculating the transition process of small fluctuation,the small fluctuation of the system is analyzed for that it is stable or not;Through hydraulic interference calculation,the interference unit＇s head,flow rate,efficiency,and unit＇s axis torque change are judged for that they exceed the allowable range or not.All these as mentioned above could provide evidence for the design of the diversion system in hydropower station.
