Abstract

The electrified railway systems have been spreading all over the world. In big cities, metro or light rail transit railway networks have been constructed extensively. Expansion of this enormous dynamic electric load has been created huge amount of stress on the power grid. Generally, the speed drives, power conversion equipment or frequency converters inject harmonic in to railways power supply system. These harmonics seriously disturbs other electrical systems or generate a high frequency electromagnetic fields in neighboring electrical equipment as well as traction network signaling system. However, new developments in power electronic converter enable efficient and flexible conditioning of electrical energy in the application of railway power system. Power electronics, already previously being a pioneer for progress of traction vehicles, brought forth an ultimate standardization of the traction power supply system. Today, the spectrum of power electronic converters application in the traction system spread in many areas including power electronics based traction transformers, auxiliary power supply systems, rectification, integration of regenerative braking, reactive power compensation and voltage regulation and traction motor controls. This paper reviews the applications of semiconductor based power electronic devices in electrified railway system and illustrates some major application areas.

电力电子变换器在牵引供电系统中的应用
电气化铁路系统已遍布世界各地。在大城市,地铁或轻轨交通路网已广泛建设。这种巨大的动态电力负荷的膨胀给电网带来了巨大的压力。铁路供电系统一般由调速装置、功率转换设备或变频器注入谐波。这些谐波严重干扰其他电气系统或在相邻电气设备以及牵引网络信号系统中产生高频电磁场。然而,电力电子变换器的新发展使电能的高效灵活调节在铁路电力系统中的应用成为可能。电力电子技术已经成为牵引车辆发展的先驱,它带来了牵引供电系统的最终标准化。如今,电力电子变流器在牵引系统中的应用范围已扩展到许多领域,包括基于电力电子的牵引变压器、辅助供电系统、整流、再生制动集成、无功补偿和电压调节以及牵引电机控制。本文综述了基于半导体的电力电子器件在电气化铁路系统中的应用,并举例说明了一些主要的应用领域。
