Variable speed wind turbines, with their many advantages compared to fixed speed wind turbines, is very promising technology for large scale wind farms. This report presents modelling and control strategies of variable speed doubly-fed induction generator (DFIG) based Type-3 wind turbine where the stator is connected directly to the three-phase grid and the rotor is connected to the grid through the bi-directional back-to-back AC-DC-AC converter. The goal of this project is modelling of DFIG wind turbines and study the operation and control of DFIG based wind turbines. To avoid complexity, the whole model is considered as a collection of subsystems which are modelled individually and then assembled to get wind turbine model. The complete model includes of general turbine aerodynamics, mechanical system, DFIG, current regulated power converters and the control system of wind turbine .The steady state and dynamic modelling of doubly-fed induction machine (DFIM) are discussed in this paper. And Vector control of rotor side converter is simulated in this paper assuming the grid side control is already done. The complete system is modelled and implemented in the power system simulation tool MATLAB/Simulink.
