郑州地铁1号线制动电阻选型方案分析

Analysis on the Selection Schemes of Braking Resistor for Zhengzhou Metro Line 1

结合国内外城市轨道交通制动电阻选型的发展趋势对制动电阻几种设置方案进行综合比较分析,最终确定郑州地铁1号线采用电阻+逆变型(回馈中压)地面化方案。该方案可将车辆制动时产生的电能有效转化利用,将本应被消耗的能量最大限度地实现回馈,达到节能减排的目标,为后续线路建设及其他城市的城市轨道交通建设提供了有益的参考。

According to the current situation and development trend of urban rail transit in the world, and with a comprehensive analysis on some selection schemes of braking resistor, the resistor and inverter （feedback to the medium voltage） on the groundis adopted for Zhengzhou Metro Line 1. This scheme could transform and utilize effectivelythe electric energy produced from train braking, and realize the maximum feedback, thus to achieve the goal of energy saving and emission reduction, and offer beneficial reference to the follow-up lines and other urban metros.
