A Brief Discussion on the Selection of Incoming Line Operation Modes and Protection Configurations for Electrified Railway Switching Stations

The establishment of switching stations in electrified railways plays a crucial role in realizing segmented power supply, enhancing power supply flexibility, and narrowing down fault scopes. By analyzing three catenary tripping faults, this paper explores the incoming line protection methods of switching stations, discusses their advantages and disadvantages, and proposes suggested schemes to enable switching stations to function more effectively.
