The invention relates to the field of internal combustion locomotive control, in particular to a low-speed control method for a reconnection direct-current transmission locomotive for realizing current complementation of a traction motor, which comprises the following steps of: S10, determining a master control locomotive and a controlled locomotive in two internal combustion locomotives adopting reconnection control, and setting the two internal combustion locomotives to be in low-speed control; s20, the main control locomotive completes traction motor current adjustment of the main control locomotive at least based on the motor current given reference value and the locomotive speed given reference value; s30, the master control locomotive determines a motor current given reference value of the controlled locomotive at least based on the motor current given reference value and sends the motor current given reference value of the controlled locomotive to the controlled locomotive; and S40, the controlled locomotive completes current adjustment of a traction motor of the controlled locomotive at least based on the given reference value of the current of the motor of the controlled locomotive so as to carry out power compensation on the main control locomotive. According to the invention, low-speed constant control under the condition of double-unit reconnection under the background of large-tonnage loading and traction can be met.

    本发明涉及内燃机车控制领域,尤其涉及一种实现牵引电机电流互补的重联直流传动机车低速控制方法,其包括以下步骤:S10.在采用重联控制的两个内燃机车中确定主控机车和被控机车,并且将两个内燃机车设置为低速控制;S20.主控机车至少基于电机电流给定基准值和机车速度给定基准值来完成主控机车的牵引电机电流调节;S30.主控机车至少基于电机电流给定基准值确定被控机车电机电流给定基准值并将被控机车电机电流给定基准值发送给被控机车;S40.被控机车至少基于被控机车电机电流给定基准值来完成被控机车的牵引电机电流调节以对主控机车实施动力补偿。本发明能够满足大吨位的装载和牵引背景下的双机重联情况下的低速恒定控制。
