Résumé :	The presented thesis presents a contribution to the control of static converters dedicated to decentralized wind turbine production. The brushless doubly-fed induction machine (BDFIM) is the basis of the studied wind energy conversion system (WECS). The grid tied WECS-BDFIM system has been controlled by different control techniques under balanced grid voltages. For the machine side converter (MSC), firstly the conventional flux-oriented control (FOC) and direct power control (DPC), use conventional regulators, were addressed. Note that these techniques ensure decoupled power regulation for the BDFM. On the other hand, for the grid side converter (GSC), the classical direct power control based on a conventional switching table (ST-DPC), based on modified switching table (IST-DPC) and the direct power control with virtual flux estimation based on the SOGI-FLL estimator, have been analyzed and simulated. We note that the technique of direct power control based flux estimation with the SOGI-FLL estimator gives very good result in terms of power quality and it will be our choice for the control of the GSC. Then, we are interested about a modified direct power control for the both converters (MSC) and (GSC) under disturbed supply condition. The extraction of positive, negative and harmonic contents of voltage and current and the calculation of compensation powers terms is conducted using synchronization techniques (SOGI-FLL, DSOGI-FLL and MSOGI-FLL). The control process of a standalone WECS-BDFIM system is performed using the Direct Voltage Control (DVC) and it has been evaluated under different transients such as a variation of load and wind speed. The detection of frequency, voltage amplitude and phase angle has been done using a DSOGI-FLL technique that is shown a satisfactory performance during disturbed voltage condition. Simulations were performed using MATLAB software to validate performance of the developed control techniques. The obtained results, demonstrate a good steady state and dynamic performance.
