The invention discloses a traction control system, which comprises a control module for controlling a traction converter and a bidirectional charger to be started after receiving an emergency power supply instruction, a storage battery pack comprising a plurality of storage batteries and being used for outputting direct currents, a traction converter for converting the direct current output by thestorage battery pack into an alternating current and outputting the alternating current to a traction motor after receiving a traction instruction so as to drive a train to run through the traction motor, a bidirectional charger for converting the direct current output by the storage battery pack into an alternating current and outputting the alternating current to an auxiliary load and/or the traction converter after receiving the traction instruction or the auxiliary instruction to enable the auxiliary load to work conveniently. Emergency power supply is started through the existing storagebattery on the train, autonomous operation of the faulty train can be achieved, the efficiency is high; meanwhile, the storage battery provides power for the auxiliary load, so that the comfort of the faulty train in the rescue returning process is improved. The invention further discloses a traction control method and a train, which have the above beneficial effects.
本发明公开了一种牵引控制系统,包括:控制模块,用于在接收到应急供电指令后,控制牵引变流器和双向充电机启动;包括多个蓄电池、用于输出直流电的蓄电池组;牵引变流器,用于在接收到牵引指令后,将蓄电池组输出的直流电转换为交流电输出至牵引电机,以通过牵引电机驱动列车运行;双向充电机,用于在接收到牵引指令或辅助指令后,将蓄电池组输出的直流电转换为交流电输出至辅助负载和/或牵引变流器,以便辅助负载工作。本发明通过列车上既有的蓄电池来启动应急供电,可以实现故障列车的自主运行,效率高,同时通过蓄电池为辅助负载供电,提高了故障的列车在救援回送过程中舒适性。本发明还公开了一种牵引控制方法及列车,具有上述有益效果。
