摘要
在“双碳”政策背景下,各行业向低碳绿色可持续发展转型。为解决目前城市轨道交通牵引供电系统整流机组二极管不可控、无法动态调配系统能源、不能实现能源高效利用的问题,柔性直流牵引供电系统应运而生。该系统将双向牵引机组与能源管控系统深度结合,牵引所输出电压及外特性可动态调节,通过能源管控系统对牵引用电潮流进行实时、动态管控,实现对各变电所功率配置及交流网络供电质量的优化,提高直流牵引供电能力,优化系统能耗。本文以北京某在建线路为例,探讨了柔性直流牵引供电系统的工程应用方案,可供相关工程参考。
Under the background of the policy of"carbon peaking and carbon neutrality",various industries are transforming to low-carbon,green and sustainable development.In order to solve the current problems of uncontrollable diode of rectifier unit in traction power supply system of urban rail transit,unable to dynamically allocate system energy,and unable to achieve efficient energy utilization,flexible DC traction power supply system came into being.The system deeply combines the two-way traction unit with the energy management and control system.The output voltage and external characteristics of the traction station can be dynamically adjusted.Through the energy management and control system,the traction power flow can be controlled in real time and dynamically,so as to optimize the power configuration of each substation and the power supply quality of the AC network,improve the DC traction power supply capacity,and optimize the system energy consumption.Taking a line under construction in Beijing as an example,the paper discusses the engineering application scheme of flexible DC traction power supply system,providing a reference for the similar projects.
