Embodiment Construction

[0041] figure 1 The ship shown in a simplified manner in includes: an onboard network with a rated voltage U1 and a rated frequency f1; a plurality of generators 4 connected to the onboard network 2, and each generator 4 is driven by a diesel engine 3 in order to generate power for the onboard network 2 ; and a load 5 connected to the onboard network 2 . An electric machine in the form of a reactive power machine (reactive power generator) 6 connected to the onboard network 2 via a smoothing choke 21 is used to generate reactive power for the onboard network 2 . Alternatively, the reactive power machine 6 can be connected directly to the onboard network 2 .

[0042] The electric generator 7 can be coupled to the reactive power machine 6 via a transmission 8 and a switch coupling 9 . The switch coupling 9 allows operative coupling and decoupling of the electric motor 7 to and from the machine 6 . The electric generator 7 is connectable via an electrical line 11 to an onshore...

Abstract

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.

Description

technical field [0001] The invention relates to a method for supplying energy to an onboard electrical power network of a ship as claimed in claim 1 and to a ship with an external energy supplier as claimed in claim 10 . A method for retrofitting such an external energy supplier is the subject-matter of claim 16 . Background technique [0002] An on-board electrical power network of a ship is known from WO 2004 / 028899 A1, via which the electric drive motors of the ship and other loads of the ship's on-board diesel generators are supplied with electrical energy. For this method of supplying energy to a ship, the diesel generators and thus the energy source for operating the drive engines and other loads of the ship are located on board the ship. The boat also has an additional diesel generator for operation while in port, which can be connected to the onboard network. Alternatively, the onboard network may be powered via an onshore connection. For this type of external ene...
