Research on the Networking Scheme of Bidirectional Converter Units in the Vehicle-ground Cooperative State

The vehicle-ground cooperative power supply mode based on bidirectional converter units is an important component of the intelligent power supply system for urban rail transit. Research the networking mode of bidirectional converter units under different line conditions is conducive to the energy-saving transformation of existing lines. It can reduced the equipment investment and maintenance workload under the premise of meeting the traction and feedback requirements.
