摘要
随着我国高速铁路的快速发展,牵引供电系统能耗高、再生制动能量利用率低等问题日益突出。为实现高速铁路的节能降耗,该文结合实测数据分析枢纽牵引变电所、长大坡道/重载线路以及铁路10k V配电所的负荷特性。针对不同牵引变电所负荷特性的差异,提出储能型和储能(10)能量回馈型2种再生制动能量利用方案,并制定相应的能量管理策略及控制方法。对所提方案进行节能效果和经济性分析,分析结果表明提出的方案能有效提高再生制动能量利用率,且具有明显的节能效果和经济性。最后,通过实验验证所提方案能量管理策略及控制方法的正确性和可行性。
With the rapid development of Chinese high-speed railways(HSR),the issues of high energy consumption,low regenerative braking energy utilization rate in traction power system have become increasingly prominent.To reduce the energy consumption and save the regenerative braking energy of the HSR,this paper analyzed the load behaviors of a hub substation,a substation with long slope and a 10 kV railway distribution network based on the field measured data.According to the difference of load profiles among different traction substations,the regenerative braking utilization schemes of energy storage and energy feedback were proposed,and corresponding energy management strategies and control methods were then formulated.The energy saving effect and economy of the traction substation have been analyzed,and the results show that the proposed regenerative braking energy utilization scheme can not only increase the regenerative braking energy utilization rate dramatically,but also have obvious energy saving effect and economy.Finally,the correctness and feasibility of schemes have been verified by experiment.
