FIELD: electricity.
SUBSTANCE: group of inventions relates to shipboard propulsors electric drive. Ship power plant comprises main diesels or turbines and main synchronous generators, on stator of which there are two three-phase, galvanically isolated windings shifted by 30 electric degrees. Stator windings are connected via automatic circuit breakers to two three-phase lines of the main switchboard, to which rectifier inputs are connected, to the output of which inputs of autonomous voltage inverters are connected, to the output of which the propulsion motors are connected. Permanent magnets are arranged on rotor of synchronous generators. To each line of main distribution board through automatic circuit breakers are connected primary windings of three-phase transformer, and secondary winding of transformer is connected to input of frequency converter. Output of frequency converter via automatic circuit breaker is connected to distribution board panel of other ship consumers. Also disclosed is an embodiment of ship electric power plant, in which rectifiers are part of main distribution board.
EFFECT: technical result consists in improvement of efficiency at reduction of weight and dimensions.
