本文针对南方某大型水电站,进行水力机组甩负荷大波动过渡过程模拟。在计算软件 Matlab 的支持下,模拟出了压力变化曲线和转速变化曲线,继而得出引水系统最大压力升高和蜗壳末端最大转速升高。通过电站实测数据与模拟结果之间的对比,验证二者之间的一致性,这种模拟和对比结果也可以为同类型水电站的调节保证计算和稳定性分析提供一定的参考。
本文針對南方某大型水電站,進行水力機組甩負荷大波動過渡過程模擬。在計算軟件 Matlab 的支持下,模擬齣瞭壓力變化麯線和轉速變化麯線,繼而得齣引水繫統最大壓力升高和蝸殼末耑最大轉速升高。通過電站實測數據與模擬結果之間的對比,驗證二者之間的一緻性,這種模擬和對比結果也可以為同類型水電站的調節保證計算和穩定性分析提供一定的參攷。

In this paper,according to the south of a large hydropower station,we simulated hydraulic turbine load rejection transient process.Under the support of calculation software matlab,pressure change curves and speed change curves were simulated,and then,the maximum pressure of the diversion system and the maximum rotating speed at the end of the spiral case has been showed.Consistency between simulation results and measured results have been verified,reference can be pro-vided for calculation of regulation guarantee for the same type hydropower station by these comparative results.
