Method for supplying external energy to an onboard power network in a ship, a ship with such a source of external energy

摘要

A method for supplying outside energy to an onboard electrical power network of a ship, a ship with such an outside energy supply and a retrofitting method for said outside supply. To supply outside energy to a ship's onboard electrical power network (2), with the ship (1) featuring an electrical machine (6) which, when the ship (1) is being supplied with its own energy, is driven by at least one energy source (3, 28) on board the ship, for supplying the ship's onboard network (2) with outside energy the electrical machine (6) is operated in accordance with the invention as a generator and is driven in this case with current from at least one energy source (13) outside the ship (1) such that it generates a current with the frequency and voltage of the onboard network (2) for feeding into the onboard network (2). The invention is particularly suitable for retrofitting an outside energy supply on board a ship.
