摘要:
牵引供电系统作为牵引动力的唯一来源，其长期供电能力与大功率随机性冲击负荷之间的平衡适应问题，以及高供电可靠性与复杂系统运行环境之间的协调匹配问题，将是开展400km／h及以上运行速度条件下高速铁路工程建设项目所需解决的关键技术问题。针对全并联AT供电系统在实际运营场景下可能出现的3种牵引网典型短路故障，分别从单边及双边供电角度，探究了牵引网系统发生不同类型故障时的电气分布特征，并基于实际牵引网悬挂类型及参数选型构建系统仿真模型，以实施短路故障仿真，从而获取牵引变电所系统及馈线侧、AT所和分区所处遭遇不同类型故障时的故障电流仿真结果。研究成果可为供电系统方案设计及优化配置提供相应的理论和技术支撑。
Abstract:
The traction power supply system is the only source of traction power. The balance between its long-term power supply capacity and high-power random impact load，and the coordination and matching between high power supply reliability and complex system operating environment will be the key technical problems to be solved in promoting the construction project of the high-speed railway with a running speed of 400 km／h or above. In this paper，aiming at 3 kinds of typical short-circuit faults of traction networks that may occur in the actual operation scenario of a fully parallel auto-transformer feeding system，the electrical distribution characteristics of the traction network system with different types of faults were explored from the perspective of unilateral and bilateral power supply，and a system simulation model was constructed based on the actual suspension type and parameter selection of traction network，so as to implement short-circuit fault simulation and obtain the fault current simulation results of traction substation system，feeder side，auto-transformer substation，and section substation when encountering different types of faults. The results can provide corresponding theoretical and technical support for the scheme design and optimal configuration of the power supply system.
