用Simulink对串级调速系统的仿真分析

本文从绕线式异步电动机的数学模型出发，推导出在任意同步旋转坐标系下电机的动态仿真框图，一改常规交流传动计算机仿真方法，应用Ｓｉｍｕｌｉｎｋ仿真软件包建立绕线式异步电动机的数学模型，并对其进行改造以方便串级调速的实现．本模型能设定几乎所用电机内部物理量的数值，可以方便地用于电机及其控制系统的稳态及其动态性能分析与研究．最后以实际的ＪＺＲ１１—６型绕线式三相异步电动机为例进行验证，证明了仿真模型的有效性和可行性．

Analysis of the Simulation of Series Speed-Regulating System with Simulink

In this paper, a dynamic structure diagram of wound- rotor asynchronous motor is proposed in an arbitrary synchronously rotating framer of reference according to its dynamic mathematics model. SIMULINK simulation software package is used to set up the mathematical model of asynchronous motor. It is a new simulation method, which is different from the routine A.C driving simulation of computer. This model can provide almost all values of physical quantities of the motor, so it can easily by used in studying of static and dynamic performance of induction motor and its drive system. Finally, the parameters of an sctual motor (JZR12- 6 type) are used to verify the validity of simulation model.
