摘要
根据变速恒频双馈发电独立电源的运行情况,提出了一种采用定子磁场定向的交流励磁变速恒频双馈发电机模型及控制策略,分析了电机运行的稳态和动态性能。仿真结果表明,采用矢量定向控制,发电机与原动机之间可以完全解耦,发电机定子电压、定子电流的频率、相位与转子的实际转速和瞬时位置无关。
Considering the characteristics of stand-alone variable-speed constant-frequency doubly-fed generator, the control model and control strategy was presented, for a variable-speed constant-frequency （VSCF） doubly-fed with AC excited rotor based on the stator field oriented vector control , the steady state and dynamic performance was discussed. The result of simulation shows that frequency and phase of the stator voltage and current are independent of the rotor speed and its instantaneous position, using vecter oriented control, a full decoupling between the mover and the generator is possible.
