Research on doubly-fed wind power generator modeling

Doubly-fed induction generator (DFIG) is obtaining more and more applications in wind power due to it´s high energy efficient and controllable reactive power. In this paper, the maximum power capturing and the process of energy conversion is introduced. And the mathematic model under the two-phase synchronous coordinator is deduced. Based on stator flux orientation, the active and reactive power decoupled control strategy is deduced. The simulation results reveals that the model built in MATLAB can achieve the aim of wind power tracing and decoupled control.
