Control of a Wind Driven DFIG Connected to the Grid Based on Field Orientation

Field orientation, with autonomous control of reactive power, using PI controller is the most widely used controlling method of doubly-fed induction generators (DFIG). This paper describes a method for separate control of active and reactive power of grid-connected DFIG using PI controller. Using MATLAB/SIMULINK software, the behavior of controller is evaluated during variation of wind speed. Simulation results represent the behavior of controller when facing the variations. This paper first explains the model of DFIG and the second part is explaining field oriented control of DFIG.
