There is provided an electric traction system, comprising: a step-down transformer comprising a primary winding for operatively coupling to an AC power supply and a secondary winding which is inductively coupled to the primary winding; a traction converter module comprising a first input terminal and a second input terminal which are operatively coupled to the secondary winding, and a plurality of AC-to-AC power converters, each of which comprises first and second input nodes, configured to receive AC power and output nodes configured to supply AC power, wherein the first and second input nodes, of the plurality of AC-to-AC power converters are electrically connected in series between the first input terminal and the second input terminal; and at least one electric motor configured to be driven by the traction converter module.

Electric traction system

Provided are a control method, apparatus and device for an automatic train operation system. The method includes: acquiring multiple preset traction distribution strategies; determining, for each traction distribution strategy, a performance index of the traction distribution strategy; determining an optimal traction distribution strategy based on performance indexes of the multiple traction distribution strategies; and controlling the automatic train operation system based on the optimal traction distribution strategy.

Energy-saving control method for automatic train operation, and related device and readable storage medium

Disclosed is an optimized energy interconnection system for an urban railway train in the technical field of urban railway transportation power supply, for addressing the technical problem that distribution of regenerative braking energy flows cannot be accurately determined. The system includes a DC intermediate bus and a multi-port flow controllable energy router. The multi-port flow controllable energy router can comprehensively control a source and a load connected in parallel on the DC intermediate bus and thus can accurately determine the distribution of regenerative braking energy flows, thereby forming a well-developed system for evaluating usage of the braking energy.
