Abstract: An electromagnetic braking system includes an electrically conductive disc coupled to a rotatable shaft of a power generation system. The rotatable shaft is operatively coupled to a prime mover and a generator. The electromagnetic braking system further includes an inducting unit for applying an electromagnetic braking torque on the electrically conductive disc when commanded by a control signal and a controller for receiving an activation signal from an activating unit, receiving a rotational signal from a rotational sensor coupled to the rotatable shaft or the generator, determining a control signal when the rotational signal is outside of a threshold, and, when the activation signal is active and the rotational signal is outside of the threshold, sending the control signal to the inducting unit to regulate a rotational dynamic of the rotatable shaft.

Abstract: A system including an electromagnetic braking system that has an eddy current brake. The eddy current brake includes an electrically conductive surface coupled to a shaft of a generator system, wherein the eddy current brake is configured to induce an electromagnetic force on the electrically conductive surface when powered. The electromagnetic braking system further includes a supercapacitor coupled to the eddy current brake, wherein the supercapacitor is configured to discharge to power the eddy current brake for the duration of a ride through event of the generator system, and the supercapacitor is configured to supply a threshold current to the eddy current brake within approximately 100 ms of a start of the ride through event.
