FIELD: power supply systems for off-line electric mains such as those of oil boring platforms or ships.
SUBSTANCE: proposed power supply system has at least one generator 3 and at least two three-phase systems 1a, 1b, 1c; generator 3 has at least two three-phase sets of windings and two three-phase current systems 1a, 1b shifted in phase and fully or partially dispensing with converter transformers; sets of generator 3 windings are spatially disposed in them in compliance with electric phase shift of three-phase systems 1a, 1b. Both three-phase current systems 1a, 1b form together primary system 1 and supply with power secondary three-phase current system 3 by means of transformer unit 4.
EFFECT: reduced mass and size.
