The invention discloses a phase selection control system and a control method suitable for passing neutral section of electric locomotive. The phase selection control system comprises an A-phase voltage and current acquisition module, a B-phase voltage and current acquisition module, a position signal induction module, a ground console, a main control module and a GTO bidirectional switch module, wherein according to the phase selection control method, the phase selection control system is used; when an electric locomotive passes through a neutral section, the electric locomotive enters a B-phase power supply arm from an A-phase power supply arm and sequentially passes through a first ground position sensor and a second ground position sensor; when the electric locomotive passes through the first ground position sensor, the phase selection control system carries out switching-off operation; and when the electric locomotive passes through the second ground position sensor, the phase selection control system performs switching-on operation. According to the invention, overvoltage and overcurrent generated when the electric locomotive passes through the neutral section can be reduced and even eliminated, and electrical equipment damage, insulation breakdown and misoperation of a relay protection device in the electric locomotive are avoided.

    本发明公开了一种适用于电力机车过分相的选相控制系统及控制方法,选相控制系统包括A相电压电流采集模块、B相电压电流采集模块、位置信号感应模块、地面控制台、主控模块和GTO双向开关模块;选相控制方法使用该选相控制系统,当电力机车进行过分相时,从A相供电臂经中性段进入到B相供电臂,会依次经过一号地面位置传感器和二号地面位置传感器;当电力机车经过一号地面位置传感器时,选相控制系统进行分闸操作;当电力机车经过二号地面位置传感器时,选相控制系统进行合闸操作。本发明能减小甚至消除电力机车在过分相时产生的过电压和过电流,避免电力机车中的电气设备损坏、绝缘击穿、继电保护装置误动作。
