摘要
利用地铁直流供电系统能耗仿真软件对不同辅助功率下制动电阻能耗进行仿真,仿真结果表明,在高峰期,辅助功率从0 k W变化到300 k W时,制动电阻能耗占回馈能量的比例由10.74%降至2.29%。对南京地铁二号线进行测试,实验验证大功率辅助电源设备的使用能够大幅降低制动电阻能耗。
The results of simulating the braking resistor energy consumption under different auxiliary powers with the simulation software of Metro DC power supply system show that the proportion of braking resistor energy consumption in feedback amount has been decreased from 2.29% from 10.74% when the auxiliary power changes from 0 kW to 300 kW at the peak period. Testing on Nanjing subway line 2 and the experiment verify that the use of high-power auxiliary power equipment is able to reduce greatly the energy consumption of braking resistor.
