Power control of variable-speed constant-frequency doubly-fed wind power generator

According to the mathematical model of the doubly-fed induction generator (DFIG) and the field-oriented vector-transformation control technique, the control strategy of the variable-speed constant-frequency wind power generator is analyzed which can realize the decoupling control of active power and reactive power of DFIG. On the experimental platform of the DFIG system which is based on TMS320LF2812, the program for decoupling control of active power and reactive power is designed. And the experimental results indicate that the control method is correct and effective.
