A pump turbine includes a runner connected to a generator motor, a water discharge controller for adjusting the quantity of water passing through the runner and a governor for detecting a rotational speed of the runner and controlling the water discharge controller to get a predetermined rotational speed of the runner. Upon a load rejection which shuts off the generator motor from an electric power system, the governor is controlled to make a target speed value of the runner after a load rejection higher than a target speed value before the load rejection. The target speed value is a reference speed to be compared with actual speed so that the governor determines when or how to open or close a water discharge controller in response to a balance between the two speeds.
