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.
