The power electronic device used usually as intermediate between the wind generator and the grid is a full rated two levels back to back converter (BTB). The BTB converter is constituted of tow PWM converters, the machine side converter (CCM) works as a rectifier and the grid side converter works as an inverter. Several DPC based control techniques (conventional DPC, predictive DPC and DPC based sliding mode approach (DPC-SMC)) have been applied on a PWM rectifier under ideal and disturbed supply voltage conditions. Moreover, the sensorless grid voltage control scheme is presented using sliding mode estimator. Two versions of sliding mode estimator have been implemented, one for the ideal and the other for the disturbed supply condition. After an extensive set of simulations following by experimental validation, the grid voltage sensorless DPC-SMC technique has been introduced the best performance with high estimation accuracy and power quality. On the other hand, in a wind energy conversion system, the grid side inverter function is ensuring permanent and stable transmission of energy to the grid. However, the extensive use of nonlinear loads led to decrease the quality of energy at the point of common coupling (PCC). Thus, the idea is to extend the inverter function with a harmonic compensation capability. Hence, analysis, design, and control of shunt active power filter (SAPF) under ideal and disturbed supply voltage conditions were an important part of this thesis. Then, an improved control circuit for SAPF system based on DPC concept combined with a Kalman filter as synchronization technique has been introduced. Furthermore, a modified voltage sensorless DPC concept based predictive model and modified sliding mode estimator has been proposed to be applied for a SAPF. Finally, the overall circuit control of the WECS system is based on the optimal findings, which are developed in this work. For the CCM and CCR converters, we have been applied the DPC-SMC and the proposed DPC approach respectively, as optimized solutions.

الوهميIndex. décimale : 622 Electro-Technique 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.Note de contenu :
