Dynamic modeling and dynamical analysis of pump-turbines in S-shaped regions during runaway operation

There is a region of pump-turbine operation, often called the S-shaped region, in which one unit rotational speed corresponds to three unit flows or torques. In this paper, the dynamic model of the pump-turbine in S-shaped regions is established by introducing the nonlinear piecewise function of rel...
