现代轨道交通与交流传动互馈试验台

Modern Rail Transportation and the Reciprocal Power-Fed AC Drive Experiment System

回顾了轨道交通电牵引传动的发展历程,说明了电力电子技术对牵引传动的重要影响。介绍了一种新型的"双逆变器-电机"能量互馈式交流传动试验系统。文中讨论了该试验系统的构成与运行原理,分析了其高效节能、控制灵活等优点,并给出了部分实验结果。最后提出了一种直线电机传动的互馈试验台的建设方案。

This paper presents the evolution of electric traction systems of railway vehicles and the impacts of power electronics on the electric traction systems. A novel Twin Inverter-Motor reciprocal power-fed AC drive experiment system is introduced in this paper. The construction and operation principle of this scheme are discussed, its high efficiency and flexibility are analyzed, and also some experimental results are provided. Finally, this paper proposes a reciprocal power-fed test-bed for linear motor drives.
