摘要
三相异步电机在工业生产和日常生活中的应用越来越广泛。为了提高电机系统的性能,优化控制模式以及改进设计方法,建立三相异步电机的仿真模型是非常有必要的。讨论了三相异步电机的高阶非线性多变量强耦合动态数学模型,并通过坐标变换把三相静止坐标系中的原始模型变换到dq轴同步旋转坐标系中相对简单的形式。利用LabVIEW建立了三相异步电机的动态模型,并使用模型对电机起动过程进行了仿真研究,得到了仿真结果。利用仿真可以客观、准确、详细、方便地获得三相异步电机的各项性能指标,仿真模型可用于对三相异步电机的各种研究中。
Three - phase induction motors are used more and more widely in industrial production and daily lives. In order to improve the performance of the motor system, optimize the control mode and improve the design method, it＇ s quite necessary to establish a three - phase induction motor simulation model. A high - order, nonlinear, multi -variable, strong- coupled dynamic mathematical model of three-phase asynchronous motor is described, and the original form under three - phase static coordinate system is transferred into the relatively simple form under dq - axis synchronous rotating coordinate system. The dynamic model of three -phase asynchronous motor is found by using LabVIEW. By means of this model, simulation is done and the results are obtained. Performances of three - phase asynchronous motor can be obtained objectively, accurately, and easily with this model, and it can be used in various studies on three- phase asynchronous motor.
