ANFIS based Control Strategy for Low Voltage Ride through Capability in DFIG based Wind Farm

Authors(2) :-B. Sudhakar Naik, S. Sunil Naik

This paper deals with the operation of doubly fed induction generator (DFIG) with Adaptive Neuro Fuzzy interface system (ANFIS) using rotor-side converter (RSC). Protection against voltage dips is very important for a transient stability in doubly fed induction generator (DFIG). Conventional crowbar circuits have been used for protection of DFIGs; however, they may be insufficient in some transient situations. Therefore, the Low Voltage Ride through (LVRT) capability was enhanced by a Demagnetization Current Controller (DCC) for the purpose of transient analysis. The main contribution of this work lies in the control of RSC using Adaptive Neuro Fuzzy interface system (ANFIS). In addition, both stator and rotor circuit electromotive forces were modeled in a DFIG. The performances of the DFIG models with DCC, without DCC and with ANFIS were compared. Modeling was carried out in a MATLAB/SIMULINK environment. A comparison of system behaviors was made between three phase faults with and without a stator rotor dynamic. Parameters for the DFIG including output voltage, speed, electrical torque variations and d–q axis rotor–stator current variations in addition to a 34.5 kV bus voltage were examined. It was found that in the DFIG model the system became stable in a short time when using an ANFIS.
