摘要
本文介绍了一种无旋转换能器的双馈感应电机的变速驱动和功率控制。采用定子磁链定向方案和转子转速估计器实现发电控制。为了验证理论分析的有效性,建立了一个5 HP DFIM原型系统和PWM功率变换器。给出了计算机模拟和实验结果来支持讨论。
Power control of a doubly fed induction machine without rotational transducers
This paper describes a variable speed drive and power control of a doubly fed induction machine (DFIM) without rotational transducers. A stator flux orientation scheme and rotor speed estimator are employed to achieve the power generating control. To show the validity of theoretical analysis, a 5 HP DFIM prototype system and PWM power converter are built. Computer simulations and experimental results are presented to support the discussion.
