Abstract
A virtual co-phase power supply system topology suitable for an electrical sectioning device at a sectioning and paralleling post (SP) includes a step-down transformer TR. A primary winding of the step-down transformer TRis electrically connected to a traction feeding section βin a train from a traction feeding section βto the traction feeding section β. Each secondary winding is electrically connected to one rectifier separately. DC buses output from the rectifiers are connected in parallel. The other end of the DC bus is electrically connected to a plurality of parallel inverter units. An LC filter is provided on a DC bus between a rectifier unit and the inverter unit, and the LC filter is connected in parallel to an energy storage unit. After filtering through the LC filter, an output end of the inverter unit is electrically connected to a primary winding of a step-up transformer TR.
