ELECTRIC ENERGY SUPPLY SYSTEM FOR A SHIP, IN PARTICULAR A NAVY SHIP THAT CAN BE OPERATED WITH A LOW IR SIGNATURE

摘要

The invention relates to an electric energy supply system for a ship, in particular for a navy ship that can be operated with a low IR signature and that is configured as an <> (AES). Said system comprises a direct current network (DC), supplied by fuel cells (1, 2, 3, 4), as a ship electrical system and network for normal propulsion and an alternating current network (AC) comprising generators, in particular for generating energy for high-speed propulsion. According to the invention, the generators (10) are motor-driven, e.g. by means of at least one gas turbine (11) or one diesel motor, preferably supercharged and the AC and DC network are interconnected in such a way that electric energy can be exchanged between them, in particular that electric energy can be withdrawn from the DC network and transferred to the AC network to start the motor-driven propulsion.
