摘　　要：在电源稀薄地区,高可靠的连续供电对铁路运营安全至关重要。当牵引变电所产生故障且无法越区供电时,为机车提供应急牵引电源可以保障乘客生命安全及货运行车安全;为在区间实现“早到发”而设置存车场,低成本的牵引电源需求日益增大;偏远地区铁路运行初期行车对数较少,供电臂的无功补偿对运营经济性改善显著。为此,本文提出一种辅助牵引电源,研究该电源系统组成、功率传递机理、控制策略及实现方式,并仿真验证了该方案的可行性及效果,为进一步工程应用奠定了基础。In the area with scarce power supply,high reliable continuous power supply is very important for the railway operation safety.When the faults are generated in the traction substation and the over-zone power supply is unable to be realized,the emergency traction power supply for the locomotive can ensure the life safety of passenger and freight traffic safety.In order to achieve early arrival and departure in the section,the demand for low-cost traction power is increasing.The running train pairs are less in the early stage of railway operation in the remote areas,and the reactive power compensation of power supply section can significantly improve the operation economy.Therefore,the paper proposes an auxiliary traction power supply,studies the system composition,power transfer mechanism,control strategy and the mode of realization of the power supply system.The feasibility and effect of the scheme are verified by the simulation,and it lays a foundation for the further engineering application.
