Transient Analysis of Pelton Turbine Prototypes
IOP Conference Series: Earth and Environmental Science, 2021 Abstract One of the most critical operating conditions in hydraulic turbines is the start-up transient. This may be characterized by the presence of several resonances, which increase the vibration and stress levels on the runners. At present, its study is of interest due to the more frequent starts and stops of the turbines in the last ...
