Now a days, wind energy is developing as a significant wellspring of unpolluted and eco-friendly energy to supplant the enormous scope utilization of expendable wellsprings of energy. Wind Energy is pulling in enthusiasm of analysts everywhere throughout the globe as one of the most significant inexhaustible wellspring of energy. Be that as it may, the primary confinements lie in factor speed wind vitality. The under and above Synchronous speeds are obtained by utilizing a bidirectional power flow converter. In this paper a systematic transfer function model of a Doubly Fed Induction Generator based wind turbine structure connected to grid is developed in Mat lab/Simulink environment. The control structure of generator and that of turbine is developed and implemented. A simple approach is proposed to obtain the gains of Proportional Integral (PI) controller. A systematic detail of this control structure is presented. Under varying load conditions, it is observed that the reactive power is controlled and power factor of the system is maintained close to unity by using this scheme. Stator flux situated vector control method is conveyed for both stator and rotor side converters to supply autonomous control of active and reactive power and keep the DC link voltage consistent.

This paper describes the modelling and control system of a wind turbine, using a doubly fed induction generator. This configuration makes the wind turbine suitable for variable speed wind energy application. The power captured by the wind turbine is converted into electrical power by the induction generator, and it is transmitted to the grid by the stator and the rotor windings. The control system generates voltage command signals for rotor converter and grid converter, respectively, in order to control the power of the wind turbine. Reactive power exchanged with the network through the converters is set to 0 VAr. The control strategy has been developed using MATLAB/Simulink. The simulation results are presented and discussed in the conclusions. Keywords: Wind energy, doubly fed induction generator, grid power, modelling, control.

This thesis presents the brushless doubly fed induction generator (BDFIG) system for wind energy conversion. The system is proposed as an advanced solution to the traditional doubly fed induction generator (DFIG) to reduce the maintenance cost and improve the system reliability of the wind turbine system. The proposed BDFIG employs two cascaded induction machines to eliminate the brushes and copper rings in DFIG. The dynamic model of BDFIG with two machines' rotors electromechanically coupled in the back-to-back converter is developed. The independent control of the active and reactive power flow is achieved by means of a four-quadrant power converter under the closed-loop stator flux oriented control scheme. In the proposed control strategy, the generator speed tracks well the reference speed, thus the maximum power extraction is achieved. The experiment was done on a 2kW BDFIG system. Simulations and experimental results from the experimental system verify the proposed system model and control design.

In this paper, we are interested in the development of a robust control of active and reactive power for a Doubly Fed Induction Generator for variable speed wind energy using hybrid control by Adaptive Fuzzy logic and Sliding Mode Controller (AFSMC). This type of control is introduced to avoid the major disadvantage of variable structures systems which is the chattering phenomenon. Using the variable structure is to ensure the high dynamic of convergence and the robustness towards parametric variations and disturbances. Whereas the fuzzy control is introduced here in order to remove residual vibrations in high frequencies. Simulation results show that the proposed control strategy gives better results.

  Wind energy generation has attracted great interests in recent years. Doubly-fed induction generator (DFIG) for wind turbines (WTs) are largely deployed, because variable-speed WTs have many advantages over fixed-speed generation such as increased energy capture, operation at maximum power point, improved efficiency and power quality. This paper presents the operation and vector control of a DFIG system, where the stator is connected directly to a stiff grid and the rotor is connected to the grid through bidirectional back-to-back AC–DC–AC converter. The basic operational characteristics, mathematical model of the aerodynamic system and vector control technique, which is used to obtain decoupled control of powers, are investigated using the software Matlab/Simulink.   Keywords: Wind turbine, doubly-fed induction generator, active and reactive power controller.

This paper presents a robust control of doubly fed induction generator for wind generation system. The whole system is presented in d-q-synchronous reference frame. We propose the implementation of adaptive control with integer model reference MRAC, fractional model reference FOMRAC with integer and fractional order control law design for active and reactive power supervision control in the doubly fed induction generator (DFIG) for wind energy systems. The objective is to realize a comparative study between the classical regulator MRAC and the proposed FO-MRAC with integer and fractional order control law in order to demonstrate the robustness of the fractional order adaptive control with fractional order integral in control law comparatively to integer order one. Performance and robustness results obtained will be presented and analyzed.
