  • Patent number: 12109914
    Abstract: The present invention relates to the technical field of train power supply and operation control, and provides a three-rail power supply control system for an electrical railway train. Power supply rails in the system are divided into a first power supply rail, a second power supply rail, and a third power supply rail, wherein the first power supply rail, the second power supply rail, and a running rail constitute a three-phase AC power supply loop, and the third power supply rail and the running rail constitute a DC power supply loop. An AC-DC-AC variable voltage variable frequency device supplies power to a train traction motor by means of the three-phase AC power supply loop and current collectors. Frequency modulation and voltage regulation power supply is conducted by means of the AC-DC-AC variable voltage variable frequency device on the ground to achieve train driving and operation control.
