Investigation on Dynamic Stresses of Pump-Turbine Runner during Start up in Turbine Mode
The startup process occurs frequently for pumped storage units. During this process, the rotating rate that changes rapidly and unsteady flow in runner cause the complex dynamic response of runner, sometimes even resonance. The sharp rise of stress and the large-amplitude dynamic stresses of runner...
