The invention provides a grid-connected control method and device for a train auxiliary power supply system, electronic equipment, a storage medium and a computer program product. The method comprises the steps of controlling a medium-voltage bus controller to be closed when it is detected that a network voltage signal of any auxiliary inverter SIV is larger than a voltage threshold value and output contactors KMA of all the auxiliary inverters SIV are in an open state; after a state signal fed back by a first auxiliary converter ACU is received, a grid connection instruction is sent to the first auxiliary converter ACU, so that the first auxiliary converter ACU closes an output contactor KMA of an auxiliary inverter SIV, the state signal is generated after the auxiliary inverter SIV is started, and the state signal is generated after the auxiliary inverter SIV is started. The first auxiliary converter ACU is one of the at least one auxiliary converter ACU; and after a feedback signal which is sent by the first auxiliary converter ACU after the output contactor KMA is closed and represents successful grid connection is received, alternating current bus voltage synchronization is carried out on other auxiliary converters ACU, and grid connection starting is completed.

    本申请提供了一种列车辅助供电系统的并网控制方法、装置、电子设备、存储介质及计算机程序产品;方法包括:所述方法包括:在检测到任意一个辅助逆变器SIV的网压信号大于电压阈值且所有辅助逆变器SIV输出接触器KMA均处于断开状态时,控制中压母线控制器闭合;在接收到第一辅助变流器ACU反馈的状态信号后,向所述第一辅助变流器ACU发送并网指令,以使所述第一辅助变流器ACU闭合辅助逆变器SIV的输出接触器KMA,所述状态信号为在所述辅助逆变器SIV启动后生成,所述第一辅助变流器ACU为所述至少一个辅助变流器ACU中的一个;在接收所述第一辅助变流器ACU在闭合输出接触器KMA后发出的表征并网成功的反馈信号后,对其他辅助变流器ACU进行交流母线电压的同步,完成并网启动。
