在区域性和地方性的3kv直流铁路线路中，接触网沿线的储能系统（ESS）可以管理来自电力制动的能量；在实际的低碳经济情景中，除了环境方面的考虑外，更好的能源利用还在于对现有和未来的变电站进行总体合理化。基于电力电子变压器和ESS的模块化多端口转换器可用于此目的。本文以某地区3千伏直流线路为例，通过仿真和GPS测量，获得了接触网上的列车电流和受电弓电压分布图。将ESS和多端口转换器放置在现有变电站内，可以计算节能。
In regional and local 3-kV dc railway lines, energy storage systems (ESS) along the catenary can manage energy coming from electrical braking; in the actual low-carbon economy scenario, besides environmental considerations, better energy utilization goes to a general rationalization of the existing and future electrical substations. Modular multiport converters based on power electronic transformers and ESS can be used for this purpose. This work analyzes as case study a regional 3-kV dc line, obtaining by simulations and GPS measurements the train current and the pantograph voltage profile on the catenary. Energy savings are calculated placing ESS and multiport converters inside existing substations.
