三相异步电动机是煤化工企业生产系统的重要组成部分。针对煤化工企业供电系统常见故障，对晃电时三相异步电动机的瞬态变化进行研究，并对电机定转子电流、转速、转矩的动态变化进行了分析；同时对晃电时负载转矩和电压跌落程度等参数对电动机的影响也进行了仿真。仿真结果表明：晃电发生时，电动机的电压、电流会出现不同程度的波动，

Three-phase asynchronous motor is an important part of coal chemical industry enterprise production system. For coal chemical in-dustry supply system common faults, transient changes Akira powerthree-phase asynchronous motors were studied,the stator rotor current, rotational speed and torque of the dynamic change are also analyzed.To shake at the same time when the electric load torque and degree of voltage sags are also simulated the influence of such parameters on the motor. Simulation results show that the sway electricity occurs, the volt-age and current of the motor will appear different degree of volatility, rotation speed and torque of the motor will radically change, thus an ad-verse impact on the motor.
