FIELD: railway transport.
SUBSTANCE: invention relates to dc electrified railway system containing traction substations converting three-phase ac current received from power system into dc current supplied through contact system to rolling stock, both equipped with regeneration system and without such system. DC traction substation with superconductor inductive energy accumulator contains power transformer, rectifier, smoothing filter with reactor, capacitor bank, superconductor inductive energy accumulator, four cryotrons, six semiconductor controllable switches, control unit of cryotrons and semiconductor switches, current and voltage transmitters. Invention makes it possible to eliminate partially of completely irregularity power consumption in system, maintain power of traction substation in operation at preset level, reduce power losses in inner and outer power supply system, reduce power rating of sets of traction substation and receive regeneration energy.
EFFECT: enhanced reliability in operation.
