This task is realized, initially, by inserting a crowbar circuit (CB) into rotor circuit, in case of voltage dip (VD), to guard it from high current and high voltage that could result from the transient flux produced by the VD. In case of no CB circuit, the system may be vulnerable to instability. Secondly, an ANFIS-controller is proposed to control both the rotor side converter (RSC) and the grid side converter (GSC). While the RSC controller regulates the electromagnetic torque, the GSC controller control both the real power and reactive power delivered to the system during normal operation conditions beside with it keeps the value of the dc link voltage fixed. To enhance the LVRT capabilities, the GSC is controlled such that it injects the necessary reactive power required during severe voltage dips to improve the LVRT capability of the DFIG. From the results, it is obvious that the hybrid ANFIS and CB circuit provide an improved LVRT responses in challenging operating conditions and within the acceptable criteria’s.
