摘要
为了对多相电机非正弦驱动系统进行研究,分析了非正弦驱动技术的原理,建立了适用于仿真的九相异步电机模型。以Matlab Simulink为开发平台,应用推广的Park变换,把自然坐标系下的电机模型转换到d-q谐波平面,并在此基础上建立了通用型的仿真模型。基于多相电机可以注入高次谐波增强电磁转矩原理,向定子侧注入1、3、5、7次电压的叠加,并对非正弦供电与正弦供电情况下的电机转速、电磁转矩波形进行了对比。仿真分析结果验证了该电机模型的正确性,以及非正弦驱动技术的优越性。
In order to study the non-sinosoidal motor drive technology, a detailed analysis of non-sinusoidal motor drive technology was accomplished. Based on the Matlab Simulink development platform,a model of nine-phase induction motor was established,especially for emulation use. By applying the generalized Park transformation, multi-phase induction motor model was converted into d-q harmonic plane. On this basis, the model of a nine-phase induction motor was built. When injected with high order harmonics, a better performance was established in rotational speed and electromagnetic torque, compared to sinusoidal supply. The emulation result shows that non-sinusoidal motor drive technology has great advantages in high power applications.
