【摘要】 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。更多还原

【Abstract】 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 provided for calculation of regulation guarantee for the same type hydropower station by these comparative results.更多还原
