The overall mathematical model of doubly-fed induction generator (DFIG) is established in this paper, a controller is designed in detail for DFIG under the strategy of stator flux orientation (SFO). Simulation studies are carried out in this paper with Matlab/Simulink under three operation states of DFIG, the simulation results verified that the controller designed can realize the decoupling of active and reactive power effectively.

In order to improve the dynamic performance, based on the analysis of the dynamic model of doubly fed induction generator (DFIG), this paper presents an improved direct power control strategy which is based on the direct control of stator active and reactive power of DFIG. The proposed method only utilizes the estimated stator flux by the stator resistance which is the only machine parameter, so as to remove the power dithering resulting from the inaccuracy associated with rotor flux estimation. In the Matlab/Simulink, simulation results for a 15KW DFIG system demonstrate the high accuracy and excellent dynamic performance during variations of active and reactive power, and revolution.
