The invention provides a control system and method for redundancy switching of a master motor and a slave motor of an electric locomotive. The control system comprises a master motor driving controller, a slave motor driving controller and a locomotive control module. The main motor driving controller is used for monitoring the communication state and the operation state of a motor main motor frequency converter; the slave motor driving controller is used for monitoring the communication state and the operation state of the slave motor frequency converter of the electric locomotive; the locomotive control module is used for determining whether the main motor frequency converter and the slave motor frequency converter fail or not according to the communication state and the operation state of the main motor frequency converter and the communication state and the operation state of the slave motor frequency converter, generating a control strategy if the main motor frequency converter and/or the slave motor frequency converter fail, and sending the control strategy to the locomotive control module. And switching the master motor and the slave motor of the motor based on the control strategy. According to the technical scheme provided by the invention, when the main motor has an irreversible fault, the slave motor can be quickly switched to the main motor, so that the locomotive runs normally.

    本申请提出一种电机车主从电机冗余切换的控制系统及方法,所述控制系统包括:主电机驱动控制器、从电机驱动控制器、机车控制模块;所述主电机驱动控制器,用于监测电机车主电机变频器的通讯状态和运行状态;所述从电机驱动控制器,用于监测电机车从电机变频器的通讯状态和运行状态;所述机车控制模块,用于根据主电机变频器的通讯状态和运行状态、所述从电机变频器的通讯状态和运行状态确定所述主电机变频器、所述从电机变频器是否故障,若所述主电机变频器和/或所述从电机变频器故障,则生成控制策略,并基于所述控制策略进行电机车主从电机切换。申请提出的技术方案,在主电机发生不可逆故障时,可将从电机快速切为主电机,使机车正常行驶。
