Abstract :
In this paper, a detailed modelling of Doubly fed Induction Generator (DFIG) and its operation in closed loop control have been realized. Vector control based on stator flux orientation method is used to control the stator Active and Reactive powers independently. Verification of vector control is investigated by creating a 3-phase short circuit at the generator terminals. A cascaded bridge 13-level inverter topology is used in the rotor circuit to study its effect on quality of supply. Further harmonic analysis comparison is done between 3-level and 13-level inverter topology. All the simulation models are built in MATLAB/Simulink software. Results and waveforms clearly show the effectiveness of vector control strategy.
