Simulation of Operating Process of Three-phase Induction Motor Under Faults Condition of One-phase Short-circuit

根据三相感应电动机在αβO坐标系下的数学模型 ,用MATLAB语言编写仿真程序 .对三相感应电动机带恒转矩负载和通风机负载稳定运行时突然发生定子一相绕组对中点短路故障的运行过程进行仿真计算 。

This author uses MATLAB language to work out simulation program according to mathematical model of asynchronous motor in α β O coordinates.The program is applied to simulate the stator one phase short-circuited fault operating process of three-phase asynchronous motor driving constant torque load or ventilator load through a real calculation example and simulated results are also analyzed here.
