一种通用的异步电动机仿真模型

从异步电动机动态数学模型出发，建立了异步电动机在任意同步旋转坐标下的仿真模型，该模型具有精度高、稳定性强，且与电机参数无关；仿真过程中，电机内部状态变量的初始值可以任意设定，并能够计算出几乎所有的电机物理量及其动态变化过程。因此，该模型可以方便地用于对变流装置、电动机及交流传动系统的稳态、动态过程研究。

A Universal Simulation Model of Induction Motor

A simulation model of induction motor is established in arbitrary synchronously rotating reference frame according to its dynamic mathematics model. The simulation model has the virtues of high accuracy and strong stability wifhocet any rektion with motor parameter variety. In the simulation process, initial values of motor interior variables can be arbitrarily assumed. The model can easily simulate the dynamic process and provide almost all values of physical quantities of motor. The simulation model, therefore, can be used to study static and dynamic performance of inverter, induction motor and AC the motor drive control system. Finally, the parameters of an actual motor are used to verify the validity of the simulation model.
