摘　　要：城市轨道交通逆变回馈型再生制动能量吸收装置有低压逆变-电阻混合型和中压能馈型2种。为了合理选择回馈型再生制动能量吸收装置,分别介绍2种再生制动能量吸收装置及其工作原理。统计北京地铁10号线应用的2种再生制动能量吸收装置的回馈电量,计算2种再生制动能量吸收装置的电能吸收比率、利用率和节能率并进行分析。分析结果表明,与低压逆变-电阻混和型再生制动能量吸收装置相比,中压能馈型再生制动能量吸收装置电能吸收比率、回馈电能利用率和节能率月平均值更高,吸收能量更高,回馈能量更多,节能效果更优,可为今后城市轨道交通回馈型再生制动能量吸收装置选型设计提供参考。There are two types of inverter feedback type regenerative brake energy absorption device for urban rail transit, namely, low voltage inverter-resistor hybrid type and medium voltage energy feedback type. To rationally select the feedback type regenerative brake energy absorption device, the paper respectively introduces two types of regenerative brake energy absorption device and their working principles. It makes statistics of the feed-back electric quantity of the two types of regenerative brake energy absorption devices used in Beijing Metro Line 10, calculates and analyzes the electric energy absorption ratio, utilization rate and energy saving rate of the two types of regenerative brake energy absorption devices. The result shows that, compared with low voltage inverter-resistor hybrid type regenerative brake energy absorption device, medium voltage energy feedback type regenerative brake energy absorption device have higher monthly average value in view of the electric energy absorption ratio, utilization ratio and energy saving rate, which absorbs more energy and feeds back more energy, with a better energy-saving effect, thus providing references for selecting feedback type regenerative brake energy absorption device for urban rail transit in the future.
