摘　　要：城轨交通已成为城市耗能大户,提升列车再生制动能量的利用率对降低牵引能耗具有重要的意义。该文在分析接触网阻抗影响列车间再生制动能量传输机理的基础上,提出一种基于旁路直流回路的城轨交通再生制动能量管理与利用新思路,建立了一种基于电力电子变换器的旁路直流回路拓扑及其控制策略,并采用情景分析法开展了可行性及有效性验证。案例研究结果表明,提出的旁路直流回路拓扑及控制策略是可行的,可实现再生制动能量利用率约10%的有效提升;与地面储能系统的集成,可减少储能装置充放电次数和充放电深度,延长储能装置的使用周期与寿命。研究成果可为城轨交通再生制动能量管理与利用提供参考。Urban rail transit(URT)has become a major energy consumer in the city,and increasing the utilization rate of train regenerative braking energy has become an important measure to reduce traction energy consumption.Based on the analysis of the influence of contact network impedance on the regenerative braking energy transmission between trains,a new idea of URT regenerative braking energy management and utilization based on bypass DC loop was proposed,also establised a power electronic converter based on the bypass DC loop and the control strategy of its topology,then verified the feasibility and effectiveness using the scenario analysis method.Study results show that the proposed bypass DC loop topology and control strategy are feasible,and it can achieve an effective increase of about 10%in regenerative braking energy utilization.Integration with the ground energy storage system can reduce the frequency and depth of charge and discharge of the energy storage device,extend the life cycle and life of the energy storage device.The research results can provide a reference for the management and utilization of regenerative braking energy in URT.
