- •
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.
