Wind energy conversion systems (WECS) are one of the most prominent clean renewable energy sources adopted by many countries due to their reduced maintenance costs and high reliable operations. Grid codes demand WECS get synchronized with the grid and supply reactive current when any grid faults are subjected. Reactive power compensation devices like STATCOM are used in wind farms. Reactive currents are generated by coordinated controlled operation of WECS and STATCOM using Phase-locked loops (PLL) based-vector control methods. Due to an imbalance in the generation and demand, WECS loses synchronism with the grid during severe faults conditions. In this paper coordinated control strategy is adopted using a Fuzzy logic controller for WECS and STATCOM during severe fault conditions is proposed. The synchronism is maintained by balancing the active powers at both ends. Fuzzy logic control delivers optimal operation by supplying reactive power through STATCOM to the wind farm balancing the voltage profile during abnormal conditions. The results show that the control algorithm of system is effective for eliminating harmonic currents, reactive power compensation and inject the active power available from the PMSG wind turbine into the load and/or grid, which allowed us to confirm the robustness of the proposed strategy.
