摘要
城市轨道交通列车编组方案影响因素众多,需综合研究确定。灵活编组能够实现客流需求与运输能力的精准匹配,提高满载率,降低牵引能耗和运营成本,对轨道交通绿色可持续发展具有重大意义。以某线路为例,对灵活编组的优势做定性和定量分析,并对“3+3”灵活编组方案的实现条件进行详细研究,结果表明:采用灵活编组方案,满载率能够提高约24.3%;牵引能耗降低约32.6%,全年可节省运营成本约1073万元,具有较好的经济效益;灵活编组对车站土建规模、场段规模均无影响;在站后折返线、停车线等区域进行解编联挂时,对配线长度基本无影响;为实现列车在线解编联挂,设备系统需增加相应的功能。
There are many factors influencing the train formation scheme of urban rail transit,which need to be determined through comprehensive study.Flexible marshalling can achieve accurate matching between passenger flow demand and transportation capacity,improve full load ratio,reduce traction energy consumption and operation cost,which is of great significance for green and sustainable development of rail transit.Taking a line as an example,the advantages of flexible marshalling are qualitatively and quantitatively analyzed,and the implementation conditions of“3+3”flexible marshalling scheme are studied in detail.The results show that:with flexible marshalling scheme,the full load ratio can be increased by about 24.3%;the traction energy consumption is reduced by about 32.6%,and the annual operation cost can be saved by about 10.73 million yuan,with good economic benefits.Flexible marshalling has no impact on the civil engineering scale of the station and the scale of the depot.When uncoupling and coupling are carried out in the turn back line,parking line and other areas behind the station,it has no effect on wiring length;In order to realize online train decoupling and coupling,the equipment system needs to add corresponding functions.
