0]INTRODUCTION


Wind turbines convert the kinetic energy present in the wind into mechanical energy by means of producing torque.
Large scale wind power projects are an attractive alternative to conventional capacity expansion.
In the present scenario , most wind turbine manufacturers now equip power generating units by induction generators.
They are operated either at fixed speed or variable speed.
Generators driven by fixed speed turbines can directly be connected to grid.
Variable speed generators need a power electron..................[:=> Show Contents <=:]

DISADVANTAGES

The wound rotor type is not reliable due to SLIP RING assembly.
Brushless DFIM has less efficiency and high cost.

APPLICATIONS

WIND MILL
Used as Wind Generators
DFIG can work in variable speed range around synchronous speed.
DFIG kept synchronized with grid uses wind source more effectively.
High power pumps and fans.
Used in hydro generators.
Used in ships¦etc

CONCLUSION

Wound rotor DFIM found commercial success in very large applications with limited speed range.
For a low cost ,highly efficient and reliable electronic cont..................[:=> Show Contents <=:]

r-synchronous modes of operation and during the transition of these two modes. This paper investigates the control dynamics of a DFIG based variable speed wind turbine during two modes of operation and subsequent transition period with a battery storage. This paper is organized as follows: In section II, system configuration is presented. The model of the turbine-generator system is given in section III. In section IV, Operation and control issues in sub- and super-synchronous modes are discussed. Simulation and discussion are given in section V. Finally, conclusions are made in section VI.

ROTOR.
Stator supply is Normal 3F supply.
Rotor supply is from power frequency converter.
Slip ring assembly used to transfer Power to rotor winding.

Brushless DFIM

Two windings adjacent to each other on the STATOR .
Windings are excited separately.

Brushless wound rotor DFIM

Similar to wound rotor DFIM but slip ring assembly is not used.
Large efficiency and less cost but instability is more.

WORKING

Field can be from rotor or stator or from both.
Both Active Power (for torque) and Reactive Power (for Flux) has to be fed to ROTOR.
