| 摘要: |
| 建立了单机与无穷大系统相连的双馈感应发电机(DFIG)数学模型,并以定子电压综合矢量恒定为控制约束,提出了一种双馈感应发电机的励磁控制策略。该控制策略仅需测量定子侧电压、电流信号,简化了控制系统。利用该策略对并网双馈感应发电机有功、无功稳态调节特性及机端三相对地突然短路的过渡过程进行了仿真研究。结果表明,该方法能够实现有功和无功的独立控制,且具有良好的动态性能。 |

| Abstract: |
| A mathematical model of DFIG(Doubly Fed Induction Generator)in a single-machineinfinite-bus system is established and its excitation control strategy with restraint of keeping stator voltage comprehensive phasor constant is presented.Using this strategy,only the currents and vol-tages at stator side are required to simplify the control system.The steady state regulation characte-ristics of active power and reactive power and the transient processes of a sudden 3-phase-to-ground short-circuit are simulated with this control strategy.It is shown that active power and reactive po-wer are controlled separately with good dynamic performance.This project is supported by Program for New Century Excellent Talents in University. |
