Modelling and Simulation of Doubly-Fed Induction Generator Connected with Wind Turbine

Abstract

This work presents the modelling of DFIG (Doubly-Fed Induction Machine) using active and reactive power transfer model and the controlling strategy of DFIG using multivariable control method. This paper also represents the free acceleration characteristics of the machine. Real/Reactive powers are used in the matrix as state variables. Multi -loop control scheme is used for the control. The controller part uses six compensators. The matrix method used this paper increased the robustness of the machine as power waveforms are independent of d-q reference variable. The simulation of modelling and controlling is done using MATLAB/SIMULINK and the waveforms are plotted.
