Ogeti, pedda suresh (2016) robust active and reactive power control schemes for a doubly fed induction generator based wind energy conversion system phd thesis. Doubly-fed induction generator (dfig) dfigs are generators which are connected to the grid on both stator and rotor sides the machine is controlled via converters connected between the rotor and the grid.
In this thesis, we emulate a wind turbine generator by driving a doubly fed induction generator (dfig) via a dc motor with variable input torque capability the two circuits of concern are the dfig and supply-side circuits. Protection and operation of the doubly fed induction generator during the grid fault are investigated in this thesis wind power growth with a 20% annual rate has been experienced the fastest.

This thesis will analyze the behavior of doubly-fed induction generators (dfig) used with wind turbines to capture wind energy and transfer it to the grid the dfig has two. Abstract this study is aimed to model and develop a stable test bed for a wind farm composed of six doubly-fed induction generators (dfigs) connected to a distribution system based on the opal-rt's emegasim® real-time digital simulator. Of igs, doubly fed induction generator (dfig) wind turbines are nowadays increasingly used in large wind farms because of their ability to supply power at constant voltage and frequency.
In a doubly fed induction generator the power electronic converter has a rating of about 30% of the machine rating whereas for the synchronous generator the rating of the power electronic converter is the same as machine rating thereby resulting in higher costs.
