牵引供电技术研究现状及关键性技术

Research Status and Key Technologies of Traction Power Supply Technology

我国电气化铁路里程稳居世界第一。牵引供电系统作为电气化铁路的能量心脏,其整体性能的优劣直接影响铁路的安全、稳定、经济运营。我国现有牵引供电系统面临着严重的电能质量问题,以及大量电分相制约列车速度等问题。为此,本文针对既有的分相供电系统与发展中的同相供电系统,分别从工作原理、发展现状、面临问题、关键技术等方面进行系统地梳理归纳。通过分析现有研究的成果以及不足之处,总结出构建新一代牵引供电系统仍需完善的关键性技术与未来研究趋势。希望为相关领域学者进行更深入的研究提供借鉴与参考。

China boasts the world’s longest electrified railway network.The traction power supply system,which serves as the vital energy hub for these railways,plays a crucial role in ensuring their safety,stability,and costeffective performance.The current traction power supply system in China is contending with significant power quality challenges,coupled with issues like restricted train speeds owing to the prevalent adoption of electrical phase splitting technology.In response to the evolving needs of traction power supply systems,this paper comprehensively reviewed the operational principles,current progress,challenges,and critical technologies of the established split-phase power supply system as well as the emerging in-phase supply system,analyzed the accomplishments and limitations of extant research,concluded the pinpointing crucial technologies that require refinement for the construction of a new generation of traction power supply systems.Additionally,the paper charted potential directions for future studies,to offer a valuable framework for academics in corresponding fields to pursue further comprehensive research.
