Description
Summary:In this article, we propose an observer-based synchronization of a Doubly Fed Induction Generator (DFIG) based-Wind Energy Conversion System (WECS). A new state-space model is represented by adding a capacitive filter in parallel with the machine and the grid. The observer then will be developed according to the new state model. The proposed controller and observer guarantees the stability of the system and its convergence to the desired magnitude and frequency. A robustness test will be conducted to test the estimation capability of the observer and the controller performances in the presence of external and internal perturbations. The simulation will be conducted using Simulink/Matlab. The obtained results will demonstrate the smooth sensorless synchronization of the DFIG based WECS.
