Low Voltage Ride Through capability improvement in a grid connected Wind Energy Conversion System using STATCOM

The wind energy generation is one of the rapidly growing energy sources. The connection of wind turbine into the grid creates number of power quality problems. This paper deals with Low Voltage Ride Through (LVRT) capability of Doubly Fed Induction Generator (DFIG) and the ride-through capability is enhanced by means of STATCOM.LVRT capability is enriched by the introduction of PI controller. This controller fulfills the various grid code requirements. Thus the performance of the STATCOM becomes much better by the robust control technique. The simulation result presents that the proposed system raises the reliability of the wind farm.
