Power Control using Fuzzy Logic Controller in DFIG Wind Farm

Abstract

This paper presents the control of fuzzy based controller for the wind form represented with equivalent double fed induction generator of power system. Voltage swags and dips can be damped out with off-line and on-line simulation. Fuzzy logic rule base is tuned input parameters of turbine blades. Fuzzy logic controller is fine tuned to obtain better performance, power control and stability criteria. Proposed work describes fuzzy logic control of induction generator speed in wind turbine application. Fuzzy controller is to used found the maximum power delivery to the infinite bus. Fully-controlled wind turbine which consists of induction generator and back-to-back converter is under estimate. Design has full control over the electrical torque, reactive power compensation, control of the speed under grid disturbances.
