Abstract

The paper deals with the detection process of energy loss in electric railway hauling vehicles. The importance of efficient energy use in railways and cost-effective rail transport tendency toward regenerative braking energy are considered. In addition, the current situation and improvement opportunities to achieve efficient energy use are examined. Seven measurement series were performed with scheduled Railjet trains between Hegyeshalom and Győr railway stations in Hungary. This railway section is related to the Hungarian State Railways' No. 1 main railway line (between Budapest-Kelenföld and Hegyeshalom state board), which is a part of the international railway line between Budapest and Vienna (capitals of Hungary and Austria, respectively). This double-track, electrified railway line with traditional ballasted superstructures and continuously welded rail tracks is important due to the international passenger and freight transport between Germany, Austria, and Hungary. The value of the regenerative braking energy can be even 20-30% of the total consumed energy. This quite enormous untapped energy can be used for several aims, e.g., for comfort energy demand (air conditioning, heating-cooling, lighting, etc.) or energy-intensive starts. The article also investigates the optimization of regenerative braking energy by seeking the energy-waste locations and the reasons for the significant consumption. The train operator's driving style and habit have been identified as one of the main reasons. Furthermore, train driver assistance systems are recommended to save energy, which is planned for future research.

电气化轨道车辆能量损耗检测过程

本文研究了电气化轨道牵引车辆能量损耗的检测过程。考虑了高效利用铁路能源的重要性和低成本铁路运输向再生制动能量发展的趋势。此外，还审查了实现有效能源利用的现状和改进机会。在匈牙利Hegyeshalom和Győr火车站之间的定期铁路喷射列车上进行了七个测量系列。这段铁路与匈牙利国家铁路的1号主要铁路线(Budapest-Kelenföld和Hegyeshalom国家委员会之间)有关，这是布达佩斯和维也纳(分别是匈牙利和奥地利的首都)之间国际铁路线的一部分。这条双轨电气化铁路线具有传统的压载上层建筑和连续焊接轨道，对于德国、奥地利和匈牙利之间的国际客运和货运至关重要。再生制动能量的价值甚至可以达到总消耗能量的20-30%。这相当巨大的未开发能源可以用于几个目的，例如，舒适的能源需求(空调，供暖-制冷，照明等)或能源密集型启动。本文还通过寻找能量浪费的位置和显著消耗的原因，对再生制动能量的优化进行了研究。列车操作员的驾驶风格和习惯被认为是主要原因之一。此外，建议使用火车驾驶员辅助系统来节省能源，这是未来研究的计划。
