Investigation and Simulation of Phase to Ground Fault in DFIG based Wind Turbine System

With advent of wind farms in large scale and capacity continuously increasing, issues related to performance of the overall system needs to be addressed. Faults produced by wind turbine generator systems will impact not only the wind farms but also the interconnected system. In this paper the modeling of a 6MW wind farm using doubly fed induction generator is described and the effects of phase to ground faults under various load conditions are studied. For the study use phasor control of the Doubly Fed Induction Generator is used.
