SIMULATION OF WIND TURBINE WITH DFIG USING PITCH ANGLE CONTROL

We are trying to reduce use of conventional energy resources by utilizing renewable energy resources. We are work on generation of wind energy effectively . we use DFIG (Doubly Fed Induction Generator) because it has the many advantage that is the separate or independent control of Active and Reactive power or to control of wind turbine power factor Dynamic behaviour of the wind turbine model can be by changing wind speed, pitch angle, load and inverter output parameters. We are try to use a pitch angle control method. Pitch angle control is the technology used to operate and control wind turbine blades angle. The system is in general either made up of electric motors and gears, or hydraulic cylinders and a power supply system. Pitch angle control method is the most popular technic for adjusting the aerodynamic pressure of the wind turbine and minimize aerodynamic risk when the wind speed is greater than its rated or set value. We use MATLAB/Simulink software for simulation .
