异步电机DTC在机车滚动试验台中的应用

Application of Asynchronous Motor DTC in Locomotive Rolling Test Rig

介绍了机车滚动试验台的基本原理,对测功机系统进行分析,选择直接转矩控制(DTC)方式实现交流异步电机的变频调速。并对异步电机直接转矩控制系统进行仿真,为其在机车滚动试验台的应用打下了基础。

This paper introduces the principle of locomotive rolling test rig,analyses dynamometer system,select direct torque control（DTC） method to achieve frequency control of induction motors,act the simulation of asynchronous motor direct torque control system,and lay the foundation for the application of locomotive rolling test rig.
