Abstract:

This paper presents a comparative study between three controllers for the Doubly Fed Induction Generator (DFIG) integrated into a wind turbine system. The active and reactive powers between the stator of DFIG and the grid are controlled independently by using three control strategies, the first called the active disturbance rejection control (ADRC), the second is the classical Proportional-Integral (PI) and the third called polynomial RST controller. First, a modeling of wind turbine and DFIG is presented. Also, in order to maximize the power of wind energy conversion, the use of MPPT control is indispensable. Then, these three control strategies are designed, simulated and their performances were tested and compared in terms of instruction tracking and robustness. The simulations were realized by Matlab/Simulink software.<
