长沙地铁1号线再生电能吸收利用装置运行分析

Analysis of Energy Absorption Device Operation in Changsha Metro Line 1

根据长沙地铁1号线双向变流型再生电能吸收利用系统设备的性能和配置情况,制定了8种不同的运行模式并进行测试跟踪,通过试验数据对比,得出各运行模式节能情况,同时对再生电能吸收利用装置的无功补偿功能进行了测试。试验表明,再生电能吸收利用装置运行时节能效果明显,减少了制动电阻的电能消耗,同时具有无功输出功能。分析结果对后续建设线路相关设计方案有参考价值。

According to the performance and configuration of the regenerated energy absorption device for Changsha metro line 1, 8 different patterns of devices were set up and tested. By comparing the experimental data, the energy-saving situation of each operation mode was obtained. At the same time, the reactive power output function of the regenerated energy absorption device was tested. Experiments showed that the energy-saving effect of regenerated energy absorption device is obvious when it is running, which reduces the energy consumption of brake resistance and has the function of reactive power output. It provided a reference value for the relevant design schemes in the subsequent construction lines.
