基与Maxwell与Simplorer的三相异步电机绕组调速系统仿真

针对电动汽车电机驱动系统的宽调速范围要求，分析一种通过改变定子绕组等效匝数来拓宽三相异步电机调速 范围的方法，由于采用该调速方法在绕组切换过程中会引起电机参数突变，目前还缺乏有效的暂态过程分析手段，无法 应对可能的电流冲击、转矩波动甚至功率器件损毁等情况。本文基于场路耦合仿真的解决思路，重点讨论如何使用 M axwell与Simplorer软件工具对绕组切换的暂态过程进行联合仿真，解决其中9抽头电机建模、端部参数提取以及控制 环路设计等问题。研究表明联合仿真结果准确，可以作为有效分析的手段。

Simulation Research on Three-phase Induction Motor Winding Change-over Speed Regulation Systems Based on Maxwell and Simplorer

ln terms of the wide speed range requirement of the traction system of EV( electric vehicle) , it introduced a method to expand the speed range of a three-phase asynchronous motor via changing the equivalent turns of stator windings. Using the method caused sudden changes of motor parameters during winding change-over, thus there''s been no mature method to analyze the transient, or to estimate potential consequences as current surge , torque disturbance or even breakdown of power devices. It based on the field-circuit coupling simulation mainly discusses the way to run Maxwell and Simplorer co-simulation for winding change-over transient analysis dealing with 9-lead motor modeling , end- winding parameter extracting and control loop design. The result displays accurate and proves to be an effective way for analysis.
