FIELD: transport.
SUBSTANCE: invention relates to electrically driven propulsion systems for transport facilities. Electrically driven propulsion plant comprises electric power source, main switchboard with generator, feeder and section circuit breakers, multiwinding transformers of frequency converter with primaries, input rectifier modules, isolator, DC link capacitors, inverters, and motor with two windings. One primary of said multiwinding transformers is connected in star circuit and another one is connected in delta circuit. Frequency converters for supply of every motor winding are integrated in common circuit by series connection of rectifier modules. Isolator is connected between extreme internal assemblies of rectifiers and capacitors of frequency converters feeding different motor windings.
EFFECT: higher reliability.
