摘要：
针对大容量异步电动机启动频繁的问题,建立大容量异步电动机在直接启动、转子串电阻启动以及软启动3种模式下的控制数学模型。利用Matlab/Simulink仿真异步电动机启动特性,对大容量异步电动机启动控制进行仿真分析,为电力系统的电机节能控制以及大容量异步电动机启动方式的选择提供理论依据。

Abstract: For the problem about the starting characteristics of large capacity asynchronous motor, the mathematical control models of the large capacity asynchronous motor are presented for the direct starting,the rotor resistance starting and the soft starting. The starting control characteristics of the large capacity asynchronous motor are analyized by Matlab/Simulink software. Based on the mathematical model analysis and the simulation analysis for the large capacity asynchronous motor, the results can provid an effective scientific evidence for the saving-energy and the starting mode selection of asynchronous motors.
Keywords: asynchronous motor of large capacity; mathematical model; starting characteristic; simulation analysis
