摘要：在转子速dq坐标系模型的基础上，建立了无刷双馈独立电源系统双同步速MT坐标系下的数学模型；通过引入功率绕组定子磁场定向控制的思想，给出了一种适合独立电源系统的矢量控制策略。系统可以根据独立运行所带负载特性的变化调整励磁电流，实现独立电源系统的变速恒频恒压发电，并间接地实现对功率因数的调节。通过仿真验证了该控制策略的正确性和有效性。

Abstract: Based on dq model at rotor speed, this paper established the MT model at double synchronous speed of the Brushless DoubleFed Generator(BDFG) standalone power supply system and proposed an effective vector control strategy which was based on power winding stator field orienting for this system. By adjusting the excitation current, this system can realize Variable Speed Constant Frequency(VSCF) and also can supply constant voltage and indirectly regulate the power factor. The simulation study verified the correctness and effectiveness.
