The invention discloses the technical field of electrified railway traction power supply, and particularly discloses a train neutral section passing excitation inrush current suppression method and device and a train neutral section passing system.The train neutral section passing excitation inrush current suppression method comprises the steps that a drive-in signal generated when a train is about to drive into a neutral section is received, and a drive-in side power supply arm and a neutral section are controlled to be conducted according to the drive-in signal; the voltage of the drive-in side power supply arm, the voltage of the drive-out side power supply arm and the voltage of the neutral section are obtained, the optimal closing angle of the thyristor is obtained by calculating the integral of the voltage of the neutral section in real time, the precision of the closing angle is remarkably improved, overvoltage and overcurrent impact on a train can be reduced to the maximum extent, practicability is higher, implementation is convenient, and popularization is easy. The popularization is convenient.

    本发明公开了电气化铁路牵引供电技术领域,并具体公开了一种列车过分相励磁涌流抑制方法、装置及列车过分相系统,包括接收列车即将驶入分相区时生成的驶入信号,根据所述驶入信号控制驶入侧供电臂和中性段导通,获取驶入侧供电臂的电压、驶出侧供电臂的电压和中性段的电压,通过实时计算中性段电压积分的方式,获取晶闸管的最佳合闸角,显著提升了合闸角的精度,还能够最大程度减小对列车的过电压和过电流冲击,实用性更强,且实施方便,便于推广。
