Abstract
During fault events in the electrical power grid nearby a synchronous generator, the rotor speed of the machine is increased, because dissipated power is below generated power. This may cause high rotor angle excursions and, hence, the machine to lose synchronism with the power grid. This paper presents a retardation device, which is able to curtail the acceleration of rotor speed during fault events. Besides, the backswing phenomenon which decelerates the rotor speed in the first few milliseconds of the fault event is discussed. Different simulation methods are addressed within the scope of work.
