匈塞铁路牵引供电设计总结及思考

Summarization and Thinking of Traction Power Supply Design of Hungary-Serbia Railway

中国铁路在“走出去”的过程中,特别是采用非中国标准的铁路项目,在设计、施工、产品等都面临巨大的挑战。结合匈塞铁路设计情况,对牵引供电仿真、接触电压计算、动态谐波效应、TSI能源子系统牵引供电设计系统验证等方面进行总结,在牵引供电仿真输入参数中列车最大电流限制、车站范围牵引供电系统阻抗及其他非牵引负荷等参数与国内不同,为后续欧洲等国际铁路牵引供电设计提供经验。在此基础上,从与国内略有不同的供电电压质量指标、非正常运行方式下供电能力、列车最大电流及功率电压曲线问题、牵引变压器运行方式及容量选择等方面进行分析,提出为使牵引供电设施与列车关系匹配,多部门需共同确定新的最优的列车功率电压曲线,结合电价政策可以选择牵引变压器同时运行互为备用方式,对国内设计、运营提供参考。

In the process of “going global”, Chinese railways, especially railway projects that adopt non-Chinese standards, are facing huge challenges in design, construction and products. Based on the design of Hungary-Serbia railway, this paper summarizes the aspects of traction power supply simulation, touch voltage calculation, dynamic harmonic effect, and TSI energy subsystem traction power supply design EC verification. In the input parameters of the traction power supply simulation, the maximum train current limit, the impedance of the station traction power supply system and other non-traction loads are different from those in China, which provide references for the follow-up design of traction power supply for European and other international railways. On this basis, the paper analyzes the power supply voltage quality, power supply capacity in abnormal operation, train maximum current and power-voltage curve, traction transformer operation mode and capacity selection, which are slightly different from those in China. It is proposed that in order to match the relationship between traction power supply and trains, multiple departments need to jointly determine the new optimal train power-voltage curve. Combined with the electricity price policy, simultaneous operation and mutual backup of traction transformers can be selected to provide references for domestic design and operation.
