- 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.
