SHIP ELECTRIC POWER GENERATOR UNIT Russian patent published in 2011 - IPC B63H21/17 

FIELD: transport.

SUBSTANCE: invention relates to ship building, particularly, to modification power generators with frequency and propulsion motors. Proposed unit comprises primary diesels or turbines and main synchronous generators with their stators connected via automatic circuit breakers to supply line of the main distribution panel, frequency converters, each made up of 12-pulse rectifier, and independent inverter. Propulsion motor is connected to output of each inverter as well as emergent diesel-generator with its stator winding being connected via automatic circuit breaker to supply line of the main distribution panel. Two identical three-phase windings with linear voltages shifted through 30 electrical degrees are arranged on stator of each main generator. Main distribution panel has two three-phase supply lines whereto connected are via automatic circuit breakers the main generator stator three-phase windings with linear voltages across them feature phase coincidence. Inputs of propulsion motor frequency inverter 12-pulse rectifiers are connected via automatic circuit breakers to two three-phase supply lines of the main distribution panel. First line transformer winding is star-connected while secondary of second supply line transformer is delta-connected.

EFFECT: higher efficiency, lower costs, weight and overall dimensions.
