针对电压型逆变器供电的交流传动机车异步电动机并联运行系统存在的轮径偏差以及特性参数差异 ,建立了基于 MATL AB- SIMUL INK的仿真模型 ,利用它所观测的轮径偏差及电机参数差异对异步电动机电流偏差的影响规律与理论分析一致
Aiming at the existence of wheel diameter deviation and characteristic parameters difference of AC drive locomotive asynchronous motor supplied by voltage inverter, a simulation model based on MATL AB-SIMUL INK is established. By using the observed wheel diameter deviation and the difference of motor parameters The influence law of the current deviation of asynchronous motor is consistent with the theoretical analysis
