This paper proposed a control strategy for rotor side PWM converter based on the stator voltage orientation. First, the mathematical models of Doubly-fed Induction Generator (DFIG) in a synchronous rotating coordinate system is derived .Then designed the control scheme for rotor side PWM converter. Finally, experimental platform for double-fed wind power generation system based on Infineon's XC2785 microcontrollers is established. The experimental results verify the feasibility and correctness of the control strategy.

The decoupled control of active and reactive power in doubly fed induction generator (DFIG) is a key technology of wind power generation system. First, this paper introduces the principle of DFIG, then proposes an useful method for decoupling control of active and reactive power by analyzing the mathematical model of DFIG and the stator-flux-oriented vector control scheme. Finally, use the Matlab/Simulink tools for simulation studies, the results indicated that the decoupling control of active and reactive power in DFIG can be efficiently implemented, which can be considered as a reference control scheme for variable-speed constant-frequency (VSCF) wind power generation system.

This paper proposes a cooperated control of the grid side converter (GSC) and rotor side converter (RSC) in doubly-fed induction generator (DFIG) wind power generation system under unbalanced grid condition. Mathematical model of doubly-fed induction generator (DFIG) and GSC under unbalanced grid voltage condition are investigated. Dual-dq current control strategies of the RSC and GSC under unbalanced grid condition are detailed studied. A cooperated control strategy of the GSC and RSC under unbalanced grid condition is proposed to provide enhance operation of DFIG system. The GSC is controlled to remove the total active power fluctuation of the system and RSC is controlled to eliminate the DFIG electromagnetic torque oscillation. Simulation based on Matlab/Simulink of a 1.5 MW DFIG prototype was carried out to validate the proposed cooperated control strategy.
