摘要:
结合丽江城市综合轨道交通项目一期工程1号线沿线自然坡度大、列车运行工况为持续爬坡和持续下坡的特点，研究有轨电车长大坡道线路牵引供电方案。通过分析计算列车上下坡能耗数据的严重不对称性，建议对正线上下行接触网在每个牵引供电区间中部并联一次，并设置并联开关。分析长大坡道上下行接触网并联后，牵引变电所的布点与接触网导线组合及重联列车追踪方式之间的关系。结果表明：重联列车紧密追踪对牵引变电所的布点有较大影响，同时接触网采用链形悬挂可以减少牵引变电所的设置。
Abstracts:
The traction power supply scheme for long and large ramp tram line is studied based on the characteristics of large natural slope, the train operation conditions of continuous climbing and descending on Line 1, which is the first phase of Lijiang Urban Comprehensive Rail Transit Project. By analyzing and calculating the serious asymmetry of the energy consumption data in the process of train climbing and descending, it is suggested to connect the contact line in the middle of each traction power supply section on the front and the down lines, and set up a parallel switch. The relationship between the distribution points of traction substations, the combination of catenary conductors and the tracking mode of coupled train is analyzed after the parallel connection of up and down catenaries on the long ramp. The results show that the close tracking of the coupled train has a great influence on the layout of the traction substations, and the adoption of chain suspension catenary can reduce the setting number of traction substations.
