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.
