A Comparative Study of the Scale Effect on the S-Shaped Characteristics of a Pump-Turbine Unit

S-shaped characteristics in turbine mode are prone to instabilities in associated transient processes. A single value of the speed factor corresponds to multiple values of the discharge factor, having the possibility of changing the operating point among the turbine, turbine brake, and reverse pump...
