Distributed maglev traction control system

The invention relates to the field of maglev transportation systems, in particular to a distributed maglev traction control system. The invention provides the distributed maglev traction control system, which comprises a plurality of traction converter modules, motor control units and data transmission equipment, and is characterized in that the traction converter modules and the motor control units are intensively arranged in a traction substation and form a communication ring network through the data transmission equipment; the motor control unit, a linear motor long stator laid along a line and a feed cable form a traction subarea; and when a maglev vehicle runs to a certain traction subarea, the motor control unit of the traction subarea controls the corresponding traction converter module to output the traction current required by the maglev vehicle through the communication ring network. Based on an optical transmission communication technology, the redundancy design principle is adopted, the real-time
