| A matrix converter is replaced with back to back converter in a variable speed wind turbine using doubly fed induction generator. Stable operation is achieved by stator flux oriented control techinque and the sytem opertaed in both sub and super synchronous modes, achieved good results.
|-
| Presented dynamic model of the DFIG, including mechanical model, generator model, and PWM voltage source coverters. Vector control strategies adapted for both the RSC and GSC to control speed and reactive power independently. controlling desigining methods, such as pole-placement method and the internal model control are used. Matlab/Simulink is used for simulation.
