| 摘 要： | 地铁牵引控制系统是决定地铁稳定运行的核心部分,地铁牵引负荷选择交流异步电机控制,提出了转差频率矢量控制方法,介绍了其工作原理并建立了数学模型。利用MATLAB/Simulink仿真软件搭建了地铁牵引传动系统模型,通过对比分析牵引电机空载起动与施加负载后相关电气特性的变化,来模拟地铁列车从空载到载客,可得牵引电机的定子磁链从无规则变化经过0.2s后快速形成规则的圆形轨迹,最后牵引电机达到稳定运行。仿真结果表明,采用转差频率矢量控制策略使地铁牵引具有良好的控制性能。

| Abstract: | Subway traction control system is the core part of determining the stable operation of subway.In this paper,the AC asynchronous motor control of subway traction load is selected,the slip frequency vector control method is put forward,its principle is introduced and the mathematical model is established.The subway traction transmission system is built by using Simulink simulation software.By analyzing the changes of electrical characteristics of traction motor from no-load starting and adding load,the change of subway train from no-load to passenger,and the stator flux of the traction motor can be obtained to quickly form a regular circular track from the non-regular change through the 0.2 s.Finally,the traction motor can be stably operated.The simulation results show that the slip frequency vector control strategy makes subway traction have good control performance. |
