Abstract :
This paper presents a new control method for doubly fed induction generator (DFIG) under conditions of unbalanced network. Under unbalanced supply voltage, common DC-link voltage is controlled by grid side converter (GSC) and control of stator output active and reactive power is controlled by rotor side converter (RSC). To control the positive sequence current of the GSC and RSC a new fuzzy logic controller is proposed. Implementing fuzzy logic controller results more precise output in positive synchronous reference frame and simultaneous elimination of torque and total active power oscillations along with both positive and negative sequence current. The simulation and analysis is done in MATLAB/SIMULINK tool.
