Abstract :
This paper analyses the rotor speed d-q mathematical model for brushless doubly-fed machine (BDFM). Applying stator flux-oriented vector control technology based on double synchronous reference frame, and adopting maximal wind energy capturing mechanism, the simulation model of BDFM wind generation system is obtained. To optimize the control scheme of the converter for the system, a voltage and current double closed-loop control method for two-stage matrix converter is presented in the paper. Simulation results verify the validity of the model and proposed control schemes.
