摘要:
针对高速永磁同步电机在运行过程中相电流谐波含量高这一问题,提出了一种基于电压注 入的高速永磁同步电机谐波抑制方法。在考虑存在谐波电流的前提下建立了高速永磁电机数学模 型,采用闭环谐波电流检测方法,提取 5 次和 7 次谐波电流,根据电机谐波数学模型计算谐波电压 补偿量,在传统的双闭环系统上设计增加了谐波电流反馈环和谐波电压补偿环,通过注入谐波电压 的方式来抑制高速永磁电机运行时相电流中的谐波分量。仿真和实验结果表明,基于电压注入的 高速永磁同步电机谐波电流抑制方法可以有效抑制电机相电流中的谐波,验证了该方法的有效性。 该方法易于实现,适应性强。
Abstract:
The phase currents of high-speed permanent magnet synchronous motor ( high-speed PMSM) contain lots of harmonics. A novel harmonic suppression method for high-speed PMSM based on voltage injection was proposed. The model of high-speed PMSM was established considering the existence of cur-rent harmonics. The closed-loop current harmonic detecting method was used to extract the fifth and sev-enth current harmonics and voltage compensation was calculated according to the model of high-speed PMSM. A feedback loop of harmonic currents and a compensation loop of harmonic voltages were designed and added into the control system,and the harmonic currents were controlled through injecting harmonic voltages. The results verify that the method based on voltage injection can suppress the harmonic currents effectively. The method has the advantage of simple realization and strong adaptability.
