In this paper, Fault ride through (FRT) capability is enhanced using dynamic voltage restorer (DVR) in a wind turbine-driven doubly fed induction generator (DFIG). For effective control of the DVR, Fuzzy based combined feed-forward and feed-back (CFFFB) voltage control is used. The performance of DVR using CFFFB with FLC control is observed during balanced and unbalanced conditions in terms of voltage sag mitigation, reduced THD, fault current control and dc-link voltage balancing. The advantage of control strategy is validated utilizing simulation of 1.5MW DFIG-WT and results shows better reactive power support during faults condition.
