摘要
This paper presents a direct model reference adaptive internal model controller (DMRAIMC) for a doubly fed induction generator used in wind farms for voltage sag ride-through. The dynamic response of the machine under fault causes voltage sag which affects the behaviour of the machine. This phenomenon is simulated using MATLAB/SIMULINK and presented. Here, the DMRAIMC is developed and it is tuned using fuzzy rules, and fuzzy rules adjustment mechanism is used in this controller to exchange the reactive power during voltage sag. The d-and q-axis rotor currents are controlled directly with DMRAIMC to improve the reactive power exchange of the system. The performance is compared with the conventional DMRAIMC with MIT rule adjustment mechanism. The flexibility of the proposed method in shunt connection with grid is illustrated.
