Wind farms must be linked to the grid during the voltage sag. Therefore, the improvement of low-voltage ride-through (LVRT) capability of wind turbine (WT) is a vitally issue. Protection system based on an interval type-2 fuzzy logic system (IT-2 FLC) is presented to improvement of LVRT capability of permanent magnet synchronous generator (PMSG) based on WT during the voltage dip. The presented control system prevents the power converters from the damaging effects of over-voltage during LVRT time. In addition to, the proposed protection system based on IT-2 FLC provides constant DC link voltage, reduces the amplitude of stator fault voltages, and enhances all response of PMSG. The proposed method is applied wind turbine using a 1.5MVA PMSG during different voltage sag types in the MATLAB/Simulation. The effectiveness of presented technique is verified by simulation results.
