Abstract : Contribution of wind electric generation to power grid has increased substantially over the last decade. Low voltage ride through capability during grid voltage disturbance is the major trouble assosciated with wind farms based on induction generator. Dynamic voltage restorer is one of the custom power devices which is an effective solution for grid voltage sag & swell mitigation. Improvement in low voltage ride through capability of wind turbine is ensured by dynamic voltage restorer through reactive power compensation. Control strategy is based on fuzzy logic controller which offers prevailing performance in contrast to conventional control techniques. The efficiency and performance of the proposed method are investigated with different simulation studies by MATLAB/Simulink software.
