摘　　要：俄罗斯高铁项目是"一带一路"倡议的重要组成部分,与我国单边供电模式不同,其牵引供电系统采用双边供电的AT供电方式。双边供电模式将直接影响牵引供电系统内部的功率潮流分布和主要供电设备容量的选取。在构建高速铁路AT供电系统双边供电模式下牵引供电仿真模型的基础上,研究功率潮流分布特性,给出牵引变压器容量分配、牵引网电压损失、牵引网各导线电流分布和电能损失的计算结果并分析主要影响因素,为双边供电模式下的牵引供电方案设计提供重要基础。The high-speed railway project in Russia is one of the most important projects for the Belt and Road initiative. Its power supply system is the two-way feeding AT system, which is different from that in China. The two-way feeding power supply system will decide the internal power flow distribution and the selection of the major devices. By building a model of the two-way feeding AT system, this paper studies its power flow distribution characteristics, calculates traction transformer capacity distribution, traction grid power loss, traction grid current distribution of each wire and energy loss, and analyzes the major influencing factors. This research laid the foundation for the traction power supply system design under the two-way feeding model.
