TRACTION NETWORK BILATERAL POWER SUPPLY RIDE-THROUGH POWER UTILIZATION SYSTEM, AND CONTROL METHOD

The present application provides a traction network two-way feeding power supply ride-through power utilization system, and a control method, relating to the technical field of electrified railway power supply. The system comprises: a power conversion device BCSa and a controller CCa that are arranged at a substation TSa; a power conversion device BCSb and a controller CCb that are arranged at a substation TSb; and a traction network OCS between the substation TSa and the substation TSb, said traction network OCS using two-way feeding power supply; the controller CCa is used for acquiring power information of the substation TSa in real time, and the controller CCb is used for acquiring power information of the substation TSb in real time; the controller CCa and the controller CCb perform information exchange in respect of an OFL via optical fiber, on the basis of the result of the information exchange, either the controller CCa controls the power conversion device BCSa to use ride-through power or the controller CCb controls the power conversion device BCSb to use ride-through power, such that ride-through power returned to the power grid meets a preset requirement.
