Active & Reactive power control in Windmills.

Voltage quality of grid connected windmills can be resolved using Dynamic VAR Technology.

To control the active and reactive power we use a AC-DC-AC model using PWM switching. The proposed wind farm controller using PWM is implimented, simulated using matlab simulink, tested and analyzed. Switching frequencies between 200Hz-2MHz can been used and total harmonic distortion THD, FFT, active power and the reactive power analysis can be made.
