Nonlinear Decoupling Control of DFIG

Abstract:

DFIG (Double Fed Induction Generator) becomes a competitive wind power form due to it needs small capacity converter and the controllable of system efficiency and power factor. Aiming at back to back three-phase voltage-type PWM converter of the doubly-fed VSCF wind turbine, the nonlinear mathematical model of the controller of rotor side and network side is constructed, the strategy of feedback linearization of nonlinear control is proposed, the decoupling control of active and reactive power of DFIG is achieved. The simulation results indicate that: this control strategy has good dynamic characteristics, and the quality of power supply of DFIG is improved.
