摘要

介绍了同步电机阻尼器磁链定向控制方法，建立了同步电机阻尼器磁链定向控制的数学模型。通过理论分析和实验证明，阻尼器磁通定向驱动系统与气隙磁通定向驱动系统具有相同的稳定性能;此外，阻尼器磁链对定子电流的谐波不敏感，利用反馈值可以改善驱动系统的动态性能。研制了一种基于阻尼器磁链定向控制的2500 kW 12/ 6hz环变同步电机驱动系统，并在国内轧钢厂得到了应用。该循环变换器由三组反并联的六脉冲桥式整流器组成，没有循环电流。

A high-performance synchronous motor field-oriented control system

The paper introduces a damper flux-oriented control method of synchronous machines, and develops a mathematical model of a synchronous motor with damper flux-oriented control. It is proved through theoretical analysis and experiments that a damper flux-oriented drive system has the same steady performance as that achieved with airgap flux-oriented control; moreover the damper flux is not sensitive to the harmonics of the stator currents, and by using the feedback value, the dynamic performances of the drive system can be improved. A 2500 kW 12/6 Hz cycloconverter synchronous motor drive system with damper flux-oriented control has been manufactured and applied in rolling mills in China. The cycloconverter consists of three sets of antiparallel six-pulse bridge rectifiers without circulating current.<>
