Abstract

The invention discloses a rail power supply system fault detection method and a device, a server and a storage medium, and relates to the technical field of rail transit. The track power supply systemfault detection method comprises the steps of generating an expected backflow proportion of an earth screen based on impedance and a pre-established actual backflow proportion prediction model; if the expected reflux ratio is not within the preset threshold range, generating a fault alarm prompt and transmitting the fault alarm promp to electronic equipment for displaying; according to the method, the fault alarm prompt of the rail power supply system is generated, the rail power supply system does not need to be put into use after a railway rail is built or the rail power supply system is put into use, adjustment of the rail power supply system is simple and convenient, and a large amount of labor cost and time cost do not need to be consumed.

Description

technical field [0001] The present application relates to the technical field of rail transit, and in particular to a fault detection method and device for a rail power supply system, a server, and a storage medium. Background technique [0002] Electrified railways require external power to provide trains with AC power frequency 25kV traction power. Therefore, traction substations are required to convert the high-voltage level (such as 110kV, 220kV, etc.) The AC power frequency 25kV voltage is then transmitted to the railway catenary to deliver energy for the train. There are a large number of high-power electrical and electronic equipment inside the traction substation. Therefore, a ground grid composed of horizontal and vertical grounding bodies such as flat steel or copper cables is installed at a specific position below the ground. The ground grid is used to collect the traction return current that leaks into the ground through the rails during the traction process of ...
