摘要:针对笼型电动机的闭式星三角启动,在分析启动过程的基础上,利用MATLAB/Simulink搭建闭式星三角启动的仿真模型，通过仿真深入研究星三角启动的动态过程。仿真结果表明,与普通的开式星三角启动相比,闭式星三角启动的电源线电流冲击幅度降低45.71%,电磁转矩脉动幅度降低41.75%,转速脉动幅度降低40%,为电机驱动系统的深入研究提供了有效模型和依据。
Abstract: A simulation model for closed star delta starting is built using MATLAB/Simulink based on the analysis of the startingprocess, and the dynamic process of the star dela starting is deeply studied through simulation.Sinulation results show that compared withordinary open star dela starting，the power line current impulse amplitude of closed star dela staring is reduced by 45.71% ，theelectromagnetic torque ripple amplitude is reduced by 41.75% , and the speed ripple amplitude is reduced by 40% ， which provides aneffective model and basis for in-depth research on motor drive systems.
