Analysis of Fault on 1.5 Mw Wind Power Plants

Abstract

Large size wind farms are booming day by day. As wind energy generated is highly dynamic and dependent on only wind, the overall system’s performance is important for profitable operation. Faults produced by wind turbine generator systems will impact not only the wind farms but also the interconnected system including the grid if proper protection is not ensured. In this paper it is proposed to model a 1.5MW wind farm using doubly fed induction generator and study the effects of phase to ground faults under various load conditions. For the study the vector control of the Doubly Fed Induction Generator is used.
