Abstract

Doubly-fed induction generators are sensitive to network faults and will be isolated from the circuit when a fault occurs. According to the new rules of the network, wind turbines should be able to continue working in fault conditions and should not be isolated from the system when the network fault occurs. This article proposes a Fuzzy-PID controller for controlling the doubly-fed induction generator rotor side converter in fault conditions. This controller is only added to the circuit in fault conditions and it reduces the current of the rotor circuit with the proper control of the rotor side converter. When the network voltage is in the normal state, rotor side converter control is performed with the PI controller. The proposed method is implemented in MATLAB Simulink software. The simulation results confirm the better performance of the proposed method in the proper control of the rotor side converter in fault conditions.
