Abstract: In DFIG, severe grid faults usually affect the wind turbine generator. Even in the extreme faults, LVRT is a solution for the grid connected wind generator. This paper deals with the LVRT enhancement through the rotor side controller explaining the co-ordinated control and feed-forward current control of the wind turbine based DFIG. The comparison is made between the controllers in accordance with the DFIG LVRT method. The approach of both controllers limits the maximum rotor current values and electromagnetic torque oscillations at the moment of occurrence and when the fault has been cleared. On the other hand, due to the PI-R controller being considered, the effects of the PI controller failure are presented. The best LVRT controller is shown when comparing the results of improved DFIG transient behavior and system stability. The outcome of this paper demonstrates that the FCRC approach to LVRT process is effective over the co-ordinated control. © 2020 IEEE.
