SHIP ELECTRIC POWER PLANT (VERSIONS) Russian patent published in 2012 - IPC B63H21/17 B63H23/24 H02J3/16 

FIELD: transport.

SUBSTANCE: invention relates to ship building, particularly, to modification power generators with frequency converters and propulsion motors. Proposed power plant is available in two versions. In compliance with first version, power plant comprises propulsion diesel or turbine and main sync generators with stator windings connected to feeder switchboard, frequency converters including rectifiers and inverters with their inputs connected to main switchboard feed line and their outputs connected to propulsion motors, standby diesel generator with stator winding connected to standby switchboard feed line. Stator of every main sync generator is furnished with two or more isolated identical three-phase windings with linear voltages at proper angle. Main switchboard has three-phase feed lines, each being connected to main generator stator three-phase windings with liner voltages at proper angle. Outputs of rectifiers are connected to multilevel inverter inputs. In compliance with second version, stator of every main sync generator is furnished with two or more isolated identical three-phase windings with phase-shifted like voltages.

EFFECT: higher efficiency and reliability.
