摘要
提出一种基于多回路理论的多相整距绕组异步感应电机建模方法,并且从绕组的空间排布出发推导出各互感参数的计算方法。与传统的基于d-q-n轴变换的数学模型相比,这一模型能够考虑转子的槽数,同时具有简洁的参数计算方法,不仅避免了传统建模方法中的折算处理,而且能够充分反映各次谐波的影响;因此具有良好的通用性与准确性,适合对多相电机在非正弦供电方式下的仿真分析研究。通过与样机试验数据的对比,验证了建模方法的正确性。
This paper presents a mathematical model for a multiphase concentrated induction machine based on multi-loop theory,and deduces the interrelated mutual inductances according to the space arrangement of coils.Compared with traditional mathematical models based on d-q-n transformation,this model has some characteristics of considering the number of slots and easier calculation of parameters,which brings some benefits of commonality and accuracy due to avoiding the necessary parameter-conversion in traditional models and considering the effects of all harmonics.These merits make it suitable for simulation and analysis of the multiphase concentrated induction machine while non-sine voltage power is supplied.The model is also verified by experimental results.
