城市轨道交通列车牵引和制动能耗实测分析
The analysis on the measured traction energy consumption and braking energy consumption of urban rail transit

针对上海地铁3、4号线列车运行能耗进行测试,分析列车牵引、惰行、制动工况下的牵引取流、牵引网网压、制动电阻电流、制动电阻电压与运行速度之间的关系,评估制动/牵引能耗比。以上海4号线为例对所选区间段进行建模仿真,再现列车运行和牵引、制动能耗过程,分析结果表明列车电阻制动能耗占牵引能耗的34.93%~55.71%,因此对制动能量通过回馈或存储的方式加以利用,其节能效果对我们国家的持续发展具有重要意义。
This paper analyses the relationship between traction current、traction network voltage、braking resistance current、braking resistance voltage and running speed under the traction、idle running and braking condition about the running energy consumption test of the shanghai metro line 3、4,and evaluates the ratio of braking and traction energy consumption. Meanwhile, take shanghai metro line 4 selected intervals for example to model and simulate, reappearing the traction and braking energy consumption process. The analysis results show that the ratio of braking and traction energy consumption in the range of 34.93%~55.71%.Thus, it’s a great significance to the sustainable development of our country which recycles the braking resistance consumption by the way of feedback or storage
