The invention discloses a multi-system regenerative braking energy absorption system which comprises a box-type converter box, a switch cabinet, a filtering cabinet and a chopping cabinet, wherein the box-type converter box is electrically connected with the switch cabinet through a lead wire a, an isolating switch d is arranged on the lead wire a, the switch cabinet, the filtering cabinet and the chopping cabinet are sequentially connected, and the input end of the switch cabinet is connected with a direct current side. Through connecting the box-type converter box with the switch cabinet by using the lead wire a, and the isolating switch d is arranged on the lead wire a, so that when a bullet train runs in an urban area, a worker disconnects the isolating switch d, the box-type converter box does not work at the moment, and energy fed back to a power grid during braking of the bullet train is consumed through the switch cabinet, the filtering cabinet and the chopping cabinet; and when the bullet train runs in the outer suburb, as alternating current is adopted for power supply in the outer suburb, the worker turns off the isolating switch d, the alternating current is rectified into direct current, and then the energy is consumed through the switch cabinet, the filtering cabinet and the chopping cabinet, so that the stability of the voltage of the power grid can be maintained through one system.

    本发明公开了一种多制式再生制动能量吸收系统,包括箱式变流箱、开关柜、滤波柜和斩波柜,箱式变流箱通过导线a与开关柜电连接,导线a上设置有隔离开关d,开关柜、滤波柜和斩波柜依次连接,且开关柜的输入端与直流侧相连。通过将箱式变流箱通过导线a与开关柜连接,且导线a上设置有隔离开关d,当动车在城区运行时,工作人员就将隔离开关d断开,此时箱式变流箱不工作,动车制动时向电网回馈的能量通过开关柜、滤波柜和斩波柜将这部分能量消耗掉;当动车在远郊运行时,由于远郊采用交流供电,工作人员关闭隔离开关d,交流电整流为直流再通过开关柜、滤波柜和斩波柜将这部分能量消耗掉,从而通过一个系统就可以维持电网电压稳定。
