Therefore, the rotor resistance unit can be used for power and over-currents control in DFIG. However, it may be insufficient to reduce oscillations in large power systems. This study aims to develop a new rotor resistance unit for low voltage ride through (LVRT) capability in DFIG. Moreover, electromotive-force (emf) models have been also developed in the stator and rotor circuit. The stator emf model of the simulation study was developed in the DFIG for accuracy and speed, while the rotor emf model was developed for over-current occurring in transient situations. In using the new rotor resistance unit and the stator-rotor emf, it was observed that the system stabilized in a short time, and the oscillations formed by the balanced and unbalanced faults on the grid side were damped.en10.1016/j.compeleceng.2020.106954info:eu-repo/semantics/closedAccessLVRTDFIGNew rotor resistance unitStator-rotor emf modelBalanced and unbalanced faultsLow-Voltage RideSliding Mode ControlFault RideThrough EnhancementDfigCapabilityStrategySchemeArticle902-s2.0-85098617375WOS:000642453900004Q1Q2
