A stator voltage oriented doubly fed induction generator control method with a disturbance observer
Due to their robustness and cost effectiveness, double fed induction generator (DFIG) based wind turbines are becoming very popular in wind energy conversion systems. Robustness of any implemented control structure can easily be lost due to nonlinearities, variations in the DFIG parameters and network voltage failures. In this study, machine parameter dependent terms will be estimated with the first order low pass filter disturbance observer, and stator voltage orientation will be applied in the experimental test bed. DSP ACE DS1103 platform is used as a digital controller.
