Active and reactive power control capability in wind generation based on BDFIG machine

The paper deals with energy generation from wind turbines with brushless doubly-fed induction generators (BDFIG). The capability for reactive power generation, while the wind turbine captures maximum wind power, is particularly analyzed. The control-side converters regulate both active and reactive powers independently. The active power is described in terms to the mechanical power. The relation between reactive powers of the control and power windings is analyzed from curves obtained via simulations.
