Definitions

  • the invention relates to a ship with generators for power generation and with electrical consumers, e.g. electric mo ⁇ tors of the ship traction system, as well as an on-board electrical system, and with converters which supply the elec ⁇ trical consumers with electrical energy either directly or by way of the on-board electrical system, as appropriate.
  • electrical consumers e.g. electric mo ⁇ tors of the ship traction system
  • converters which supply the elec ⁇ trical consumers with electrical energy either directly or by way of the on-board electrical system, as appropriate.
  • WO 2004/028899 Al discloses the electrotechnical equipment of a ship, which corresponds to the above. Furthermore, the known electrotechnical equipment still comprises a generator for operation when in port, which can be replaced by a shore connection by way of a plug-in connector. When the shore connection is plugged in, it assumes the energy supply of the ship in the harbor. To enable assumption of the function, the shore connection must supply electricity at the voltage and frequency of the on-board electrical system. It is disadvan ⁇ tageous here that these types of shore connection must be es ⁇ pecially directed to the requirements of the supplied ship and are thus only rarely available.
  • a converter designed to be controllable in terms of frequency and voltage and in- stalled on board the ship can be connected to a shore-side power supply line by way of a switched electrical line.
  • This ensures the possibility of switching to shore-side electric ⁇ ity at any time without any problem by means of the ship' s own components, without a large number of shore connections with different electrical equipment having to be available on shore.
  • This gives rise to hitherto unachieved flexibility at low-cost, since a converter is mostly already available on board, which is converted into a shore connection converter when in harbor.
  • the monitoring devices available on board can also continue to be used.
  • the shore connection converter used is designed such that it can convert any input voltages and frequencies into voltages and frequencies, which are cur ⁇ rently present in the on-board electrical system.
  • On-board electrical systems also experience certain fluctuations in their voltage and their frequencies. It has thus hitherto been necessary for the onboard voltage and frequency to cor ⁇ respond to the voltage and frequency of the shore connection.
  • the onboard electrical system must thus always be adjusted to the shore connection values. This is not the case in accor- dance with the invention, since the converter is able to bal ⁇ ance out the differences between the voltage and the fre ⁇ quency in a dynamic fashion.
  • a simple connection to the shore electricity, together with adjustment of the output of the converter to the respective frequency voltage and phase posi- tion of the on-board electrical system is sufficient to sup ⁇ ply the ship with electrical energy when in port.
  • Synchronization of the onboard electrical system with the shore net ⁇ work i.e. changing the onboard frequency and voltage to net ⁇ work values on land, is very advantageously no longer neces- sary.
  • the shore connection converter comprises a control and regulating device, which, in the case of a changed power requirement on the output side, which manifests itself in a tendency towards a frequency change, adjusts the power output accordingly and keeps the frequency steady.
  • a control and regulating device which, in the case of a changed power requirement on the output side, which manifests itself in a tendency towards a frequency change, adjusts the power output accordingly and keeps the frequency steady.
  • the shore connection converter keeps the frequency and voltage in the on-board electrical system steady, without the crew of the ship having to intervene after connection to the shore connection converter.
  • the shore connection converter com ⁇ prises control and regulating components, in particular soft ⁇ ware-based components, which respond to a voltage drop or a voltage increase in the ship's network, e.g. by connecting or disconnecting generators or consumers, by means of frequency increase or reduction.
  • the shore connection converter can thus deploy its advantageous effect for the on-board electri ⁇ cal system.
  • the shore connection con ⁇ verter comprise a regulating device which enables four- quadrant operation, thereby rendering particularly favorable operation of the shore connection possible.
  • the land connection advantageously comprises a switched elec ⁇ trical line to the land connection converter within the ship and a moveable part outside the ship, e.g. in the form of a cable with a plug-in connector, to enable simple usage of the shore electricity.
  • a converter is mostly already present on board the ship, and comprises supply and discharge lines which can be used, only one additional switch and one short permanent connector frequently exist within the ship, as well as an outward plug-in connector. Changeover is thus very cost-effective .
  • a very great variety of shore connection converters can be used.
  • a PWM converter is particularly advantageous, on the one side of which the shore electricity with its voltage and frequency can be fed in and the other side of which then sup- plies the onboard electricity at the necessary voltage and frequency .
  • transformer which is advantageously carried on board, can also be an auto-transformer and should have different tapping points.
  • An adjustment to the most varied of voltage levels on shore is possible, without the shore connection converter having to be attuned to a very wide variety of voltages .
  • the conversion of the typically used 60 Hz input current into the possible 50 Hz onboard current or vice versa is no problem for a converter.
  • a converter using intermediate circuit technol ⁇ ogy is very advantageous, particularly if it has a static component in the regulator.
  • Two parts which are controlled and regulated independently of one another are provided in- ternally, between which parts electrical energy is trans ⁇ ferred.
  • This is a conventional solution, as to how the used converter and its controllers and regulators actually only require software adjustment, which is known to a person skilled in the art .
  • the invention is particularly favorable for ships having electrical traction systems. These can be both propeller drive engines as well as boosters on the propeller shaft. Nevertheless, ships with shaft generator systems also have the necessary large converter on board, which, in accordance with the invention, should be used for the operation in port. Boosters and shaft generator systems are nowadays already widespread in container ships, so that container ships with their large electrical energy requirements for operating reefer containers have proven themselves inter alia as par ⁇ ticularly suitable for the inventive solution. Cruise ships with their high hotel load while in port too, where up to 15 KW can be consumed, and which are nowadays already equipped with electrical drives for ride comfort purposes, are well suited to the application of the invention.
