Abstract

The invention provides a traction network bilateral power supply crossing power utilization system and a control method, and relates to the technical field of electrified railway power supply. Including power conversion device BCSa and controller CCa installed in substation TSa, power conversion device BCSb and controller CCb installed in substation TSb, the traction network OCS between substation TSa and substation TSb adopts bilateral Power supply; the controller CCa is used to obtain the power information of the substation TSa in real time, and the controller CCb is used to obtain the power information of the substation TSb in real time; the controller CCa and the controller CCb exchange information with the OFL through the optical fiber, and the controller CCa Control the power conversion device BCSa to use the ride-through power according to the information interaction result or the controller CCb controls the power conversion device BCSb to use the ride-through power according to the information interaction result, so that the ride-through power returned to the grid meets the preset requirements.

Description

technical field

[0001] The invention relates to the technical field of AC electrified railway traction power supply, in particular to a traction network bilateral power supply ride-through power utilization system and a control method. Background technique

[0002] Electric phase separation of electrified railways is a weak link in the entire traction power supply system. The neutral section of the electric phase separation forms a no-power area, resulting in interruption of power supply. Although the no-power zone in the neutral section is generally only a few tens of meters, the train control automatically over-phases. The distance of the power outage is more than 500 meters, which seriously restricts the good operation of the train, and even causes the train to stop on the slope when going uphill. The bilateral power supply of the electrified railway can cancel the electrical phase separation where the partition is located, eliminate the powerless area here, ensure the un...
