摘要
建立了基于多回路理论的多相整距绕组感应电机的机电动力系统模型,并从绕组的空间排布出发推导出各互感参数的计算方法。这一模型可考虑转子的槽数,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。通过与样机实验数据的对比,验证了建模方法的正确性。
This paper presents the electromechanical dynamic system simulator of multiphase concentrated induction machine based on Multi-Loop Theory,and deduces the interrelated mutual-inductances according to the space arrangement of coils.This simulator 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 model and considering the effects of all harmonics.These merits make it suitable for simulation and analysis of multiphase concentrated induction machine while non-sine voltage power is supplied.The simulator is also verified by experimental results.
