THE ADRC LINEAR POWER CONTROL APPLIED TO THE WIND TURBINE SYSTEM BASED ON DFIG

This paper present the model and test of the robustness of the linear Active Disturbance Rejection Control (ADRC) applied to the Doubly Fed Induction Generator (DFIG) inserted in Wind Energy Conversion System (WECS). The objective is to show the tracking of the references and to prove the robustness of this control against internal parameters variations of the DFIG, in order to show their performances. Firstly we start by modeling the components of the Aeolian conversion chain (wind turbine, MPPT strategy, DFIG and the power converters). Thereafter, we study in detail the principle and performance of the ADRC technique used in the control of Rotor Side Converter (RSC) and Grid Side Converter (GSC). Using the Matlab/Simulink environment we present the simulation results of this control and their interpretations.
