FIELD: electricity.SUBSTANCE: marine electric power plant comprises main engines or turbines, main synchronous generators, stator windings, automatic circuit-breakers, the main switchboard, transformers, frequency converters, power supply lines, propulsion motors. The primary windings of three-phase transformers are connected to three-phase lines of the main switchboard, the secondary three-phase windings of the transformers are connected in parallel to the three-phase line of the switchboard for the remaining shipboard consumers as well as an emergency diesel generator, which stator winding through the automatic circuit-breaker is connected to the supply line of the emergency switchboard. Two and more synchronous generators are coupled to the shaft of each main diesel engine or turbine, and each generator has an independent voltage stabilisation system.EFFECT: high efficiency factor, high quality of electric energy in the shipboard network.1 dwg |
