变速恒频无刷双馈风力发电机控制策略的研究

his paper analyses the mathematical model for BDFM (brushless doubly fed machine) based on synchronous coordinates in the point of rotor speed d-q model. A power control system is designed by using power windings flux linkage oriented control technology. This system realizes the decoupling control of active and reactive power of VSCF (variable speed constant frequency ) generator by using the control windings of the generator to carry out the AC excitation. Computer simulation results verify the correctness and effectiveness of VSCF.
