•: Active Crowbar Protection (ACB_P) system is proposed to enhance the FRT capability of DFIG.
•: Proposed protection scheme is designed with a capacitor in series with the resistor.
•: Importance of ACB_P is to maintain the connection of DFIG with the grid during fault conditions.
•: Capacitor in the protection circuit eliminate the ripples generated in the rotor current.
