STATCOM with Fuzzy-PI Controller for Low Voltage-Ride through Enhancement of DFIG based Wind Farm

This paper represents the study of Fuzzy Logic Control-Based STATCOM devices to enhance the capabilities of the low voltage-ride through of a grid connected DFIG based wind farm and its comparison with conventional STATCOM device. The proposed FLC based STATCOM device have designed using MATLAB/Simulink.Compare to the output responses of the voltage, currents, speed, real power and reactive power of both stator as well as rotor of the two investigated systems during grid faults, the STATCOM with fuzzy-PI controller gives best performance with faster recovery, adjustable speed, smoother current profiles and better reliable than traditional controller.
