The invention provides an auxiliary converter grid-connected control method and device, a storage medium and electronic equipment. The auxiliary converter grid-connected control method comprises the following steps: detecting overcurrent protection signals of all auxiliary converters in a train in real time; if overcurrent protection signals reported by all the auxiliary converters are received, feedback signals reported by all the auxiliary converters according to internal detection results are received under the condition that all the auxiliary converters are restarted and internal detection is carried out; performing grid-connected power supply control on the auxiliary converter of which the feedback signal is an internal medium-voltage starting completion signal; and in the grid-connected power supply control process, if the first auxiliary converter receiving the grid-connected instruction reports an overcurrent protection signal again, determining that the train power supply has an external short-circuit fault. According to the invention, the grid-connected success rate and the grid-connected efficiency of the auxiliary converter are improved, so that the timeliness of the load work of the vehicle-mounted equipment can be controlled to the maximum extent.
本发明提供了一种辅助变流器并网控制方法、装置、存储介质及电子设备。所述辅助变流器并网控制方法,包括:实时检测列车中所有辅助变流器的过流保护信号;若接收到所有辅助变流器上报的过流保护信号,则在所有辅助变流器重新启动并进行内部检测的情况下,接收所有辅助变流器根据内部检测结果上报的反馈信号;对所述反馈信号为内部中压启动完成信号的辅助变流器进行并网供电控制;在所述并网供电控制过程中,若接收到并网指令的首台辅助变流器再次上报过流保护信号,则确定列车供电出现外部短路故障。本发明提高了辅助变流器并网的成功率和并网效率,从而能最大程度控制车载设备负载工作的及时性。
