Abstract
A power supply system for a water-bound device and to an operating method, the water-bound device having an electric shaft and in particular a first zone and a second zone, the system includes: a first DC voltage bus for a first DC voltage and a second DC voltage bus for a second DC voltage; a first energy source and a second energy source, the first energy source being provided in the first zone for supplying at least one DC voltage bus of the at least two DC voltage buses, and the second energy source being provided in the second zone for supplying at least one DC voltage bus of the at least two DC voltage buses, the energy supply system being structured at least partially in a zone-dependent manner.
Claims13
A power supply system for a water-bound facility, comprising:
- an electrical shaft, wherein the electrical shaft is connectable to a first DC voltage bus for a first DC voltage and to a second DC voltage bus for a second DC voltage,
- wherein the electrical shaft comprises at least one variable-speed generator, driven by an internal combustion engine, for producing a motor voltage having variable amplitude and variable frequency and at least one variable-speed drive motor that is supplied with this motor voltage and coupled to a propulsion unit,
- wherein the first DC voltage bus is intended for a first DC voltage and the second DC voltage bus is intended for a second DC voltage, the first DC voltage being higher than the second DC voltage, and
- a coupling between the first DC bus and the second DC bus, wherein electrical power is transported from a low-voltage DC voltage bus to a higher-voltage DC voltage bus in order to supply at least one electrical shaft with electrical power.
