摘要:: 针对城市轨道交通供电牵引负荷对城网的影响,结合郑州轨道交通1,2号线的规划设计数据,对近期、中期和远期轨道交通线网规模,采用经验公式法对牵引电量进行了具体的量化计算；运用回归分析法进行负荷预测,对郑州轨道交通牵引负荷对城市配电网的影响进行评价,结果表明:轨道交通电力峰值负荷和城网峰值负荷基本不会重叠,负荷峰值最大贡献率约2％,因此,郑州轨道交通系统负荷对电网的影响相对较小.

Abstract:: In view of the impact of metro traction power load on the urban network ， according to the pre-designdata and the short 、 mid and long-term metro transit scale of Zhengzhou metro transit line 1 and 2， this paperused the average volume method to obtain the transit supply power by specifically quantum calculation ， and theload forecast can be got with linear regression method. Finally，the evaluation of the impacts of Zhengzhoumetro traction power supply system to urban distribution network can be achieved. The analysis showed thatthe contribution rate of rail transport electricity to the distribution network is about 2% , and the rail transitpeak load with urban network peak load does not overlap, so the impact of Zhengzhou rail transit system elec-tricity grid is very small. Its conclusions can provide a reference for the network planning in Zhengzhou.
