浅析城轨交通列车再生制动能量回馈利用装置

Analysis of Urban Rail Transit Train Regenerative Braking Energy Feedback Utilization Device

充分发挥列车再生制动能力,对于减少列车闸瓦磨耗、降低牵引系统能耗具有重要作用。一种中压型的列车再生制动能量回馈利用装置（简称中压能馈装置）,集列车制动能量回馈、牵引供电、以及无功补偿等多种功能于一体,不仅具有显著的节能效果,还能减小直流网压波动,提高供电品质。论文介绍了中压能馈装置的功能特点、构成原理及应用方案,北京地铁10号线现场试验及测试数据表明,该设备运行可靠、节能效果显著。

The full play of the braking ability for reduction of train brake shoe wear and reduce the traction energy consumption of the system plays an important role. The train of a medium pressure type regenerative braking energy feedback and utilization device（referred to as the medium voltage feedback device）, set of train braking energy feedback, traction power supply, and reactive power compensation and other functions in one, not only has significant energy-saving effect, it can also reduce the DC voltage fluctuation,high power supply quality. This paper introduces the functional characteristics, the structure principle and application of the medium pressure energy feeding device. The field test and test data of Beijing Metro Line 10 show that the equipment is reliable and effective.
