This paper presents a comprehensive study of the fuzzy based LVRT of grid-connected DFIG-based windturbines. It provides a detailed investigation of the transient characteristics and the dynamic behaviour of DFIGs duringsymmetrical and asymmetrical grid voltage sags. A detailed theoretical study supported by computer simulations isprovided. This paper also provides a new rotor-side control scheme for DFIG-based wind turbines to enhance its LVRTcapability during severe grid voltage sags. The proposed control strategy focuses on mitigating the rotor-side voltageand current shock during abnormal grid conditions, without any additional cost or reliability issues. As a result, theDFIG performance is improved and utility company standards are fulfilled. Computer simulations are used to verify theexpanded ride-through capability of the novel strategy and its effective performance compared to the conventionalcontrol schemes
