Description

Die Erfindung betrifft ein Antriebssystem für ein Schiff.The invention relates to a drive system for a ship.

Schiffe der in Rede stehenden Art sind insbesondere als Binnenschiffe, das heißt Frachtschiffe, die auf Binnengewässern fahren, ausgebildet.Ships of the type in question are designed, in particular, as inland vessels, that is to say freighters operating on inland waters.

Derartige Binnenschiffe weisen als Antriebsaggregat einen Dieselmotor auf, mit dem ein oder mehrere Antriebswellen mit jeweils einem Propeller angetrieben werden.Such inland vessels have as a drive unit to a diesel engine, with which one or more drive shafts are driven, each with a propeller.

Diese Binnenschiffe werden in vier unterschiedlichen Modes betrieben, nämlich dem Mode der Bergfahrt bei voll beladenem Schiff, den Modes der Talfahrt bei voll beladenem beziehungsweise leerem Schiff und dem Mode der Kanalfahrt.These inland vessels are operated in four different modes, namely the mode of uphill travel with fully loaded ship, the modes of descent in fully loaded or empty ship and the fashion of the canal cruise.

Die Auslegung der Antriebsleistung erfolgt dabei stets so, dass diese nach dem größtmöglichen Lastfall, nämlich der Bergfahrt bei voll beladenem Schiff, ausgelegt wird, um stets eine Leistungsreserve zur Verfügung zu haben, die ein Manövrieren des Schiffs auch unter ungünstigsten Bedingungen gewährleistet.The design of the drive power is always carried out so that it is designed for the largest possible load case, namely the uphill with fully loaded ship, to always have a power reserve available, which ensures maneuvering of the ship even under the most unfavorable conditions.

Nachteilig hierbei ist, dass in den meisten Modes, insbesondere dem Mode der Talfahrt und dem Mode der Kanalfahrt nur ein geringer Bruchteil der erzeugten Leistung benötigt wird, so dass das Antriebsaggregat in einem energetisch ungünstigen Teilfahrtbetrieb betrieben wird.The disadvantage here is that in most modes, in particular the mode of descent and the mode of channel travel only a small fraction of the power generated is needed, so that the drive unit is operated in an energetically unfavorable partial travel operation.

Weiterhin ist nachteilig, dass bei derartigen Binnenschiffen der Dieselmotor der oder den Antriebswellen unmittelbar räumlich zugeordnet sein muss, das heißt das gesamte Antriebssystem befindet sich im Heckbereich, so dass dieser Bereich nicht als Laderaum zur Verfügung steht.Another disadvantage is that in such vessels the diesel engine or the drive shafts must be assigned directly spatially, the means the entire drive system is located in the rear area, so this area is not available as a cargo space.

Aus der DE 35 31 990 A1 ist ein Antriebssystem für ein Fahrgastschiff bekannt. Dieses Antriebssystem weist als Antriebsmotor einen langsam laufenden Dieselmotor auf, der so ausgelegt ist, dass er die maximal benötigte Reisegeschwindigkeit abdeckt. Für den darüber hinaus gehenden Leistungsbedarf zum Erreichen der Spitzengeschwindigkeit ist mit dem Dieselmotor ein elektrischer Motor in Reihe geschaltet. Die Erzeugung der elektrischen Energie hierfür erfolgt mittels einer Anordnung schnell laufender Viertaktmotoren.From the DE 35 31 990 A1 is known a drive system for a passenger ship. This drive system has as a drive motor on a slow-running diesel engine, which is designed so that it covers the maximum travel speed required. For the additional power required to reach the top speed, an electric motor is connected in series with the diesel engine. The generation of electrical energy for this purpose by means of an arrangement of fast-running four-stroke engines.

Aus der DE 102 31 152 A1 ist ein Schiff, insbesondere ein Marine-(Navy-) Schiff bekannt, das mehrere Antriebe, die insbesondere mit Propellern ausgestattet sein können, aufweist. Die Antriebe werden über ein elektrisches Energieversorgungssystem versorgt. Dieses umfasst Brennstoffzellen die ein Gleichstromnetz speisen, mit dem die Energieversorgung von Normalfahrtantrieben erfolgt. Zudem umfasst das Energieversorgungssystem ein Wechselstromnetz mit Generatoren zur Energieversorgung für Schnellfahrtantriebe. Zwischen dem Gleich- und Wechselstromnetz kann Energie ausgetauscht werden.From the DE 102 31 152 A1 is a ship, in particular a marine (Navy) ship known, the multiple drives, which may be equipped in particular with propellers. The drives are powered by an electrical power supply system. This includes fuel cells that feed a DC grid, with which the power supply of normal drive drives takes place. In addition, the power supply system includes an AC power grid with generators for powering high-speed propulsion systems. Energy can be exchanged between the DC and AC mains.

Der Erfindung liegt die Aufgabe zugrunde, ein Antriebssystem für ein Schiff bereitzustellen, mittels dessen eine Verbesserung der Wirtschaftlichkeit des Betriebs des Schiffes erzielt wird.The invention has for its object to provide a drive system for a ship, by means of which an improvement in the efficiency of the operation of the ship is achieved.

Zur Lösung dieser Aufgabe sind die Merkmale des Anspruchs 1 vorgesehen. Vorteilhafte Ausführungsformen und zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.To solve this problem, the features of claim 1 are provided. Advantageous embodiments and expedient developments of the invention are described in the subclaims.

Das erfindungsgemäße Antriebssystem für ein Schiff umfasst Komponenten, die ein modulares System bilden und die räumlich innerhalb des Schiffs separierbar angeordnet sind. Erste modulare Einheiten sind von Antriebswellen mit jeweils einem Propeller und einer Mehrfachanordnung von elektrischen Antrieben auf jeweils einer Antriebswelle gebildet. Generatoren bilden als Energieversorgung für die elektrischen Antriebe zweite modulare Einheiten. Steuermittel bilden zur selektiven Aktivierung und Steuerung der elektrischen Antriebe und Generatoren dritte modulare Einheiten.The propulsion system according to the invention for a ship comprises components which form a modular system and which are arranged spatially separable within the ship. First modular units are of drive shafts with each formed a propeller and a multiple arrangement of electric drives on each of a drive shaft. Generators form second modular units as energy supply for the electric drives. Control means form for the selective activation and control of the electric drives and generators third modular units.

Durch den modularen Aufbau des Antriebssystems wird einerseits eine flexible und kostengünstige Montage der Komponenten dieses Antriebssystems ermöglicht. Weiterhin können durch die räumliche Separierbarkeit die einzelnen modularen Einheiten an optimierten Einbauorten des Schiffs angeordnet werden, wodurch die Wirtschaftlichkeit des Schiffsbetriebs erhöht werden kann.Due to the modular design of the drive system, a flexible and cost-effective installation of the components of this drive system is made possible on the one hand. Furthermore, the spatial separability, the individual modular units can be placed at optimized installation locations of the ship, whereby the efficiency of the ship operation can be increased.

Dieser Vorteil zeigt sich insbesondere bei Binnenschiffen, auf welche im Folgenden ohne Beschränkung der Allgemeinheit Bezug genommen wird.This advantage is particularly evident in inland waterway vessels, which are referred to below without restriction of generality.

Bei dem erfindungsgemäßen Antriebssystem bilden die Antriebswelle oder die Antriebswellen mit den darauf angeordneten elektrischen Antrieben und Propeller eine oder mehrere erste modulare Einheiten, die von den Generatoren als zweite modulare Einheiten unabhängig installiert werden können.In the drive system according to the invention, the drive shaft or drive shafts with the electric drives and propellers arranged thereon form one or more first modular units which can be installed independently by the generators as second modular units.

Damit können die Antriebswellen mit den elektrischen Antrieben im Heckbereich des Schiffes angeordnet werden, während die Generatoren im Bugbereich angeordnet werden können. Da somit die Generatoren als großvolumige Energieversorgungseinheiten aus dem Heckbereich herausverlagert sind, steht dieser frei gewordene Heckbereich als Ladefläche für zu ladende Fracht zur Verfügung. Bei sämtlichen Binnenschiffen ist der Heckbereich erheblich breiter als der nach vorne schmal zulaufende Bugbereich. Durch die erfindungsgemäße Verlagerung der Generatoren als Energieversorgungseinheiten in den Bugbereich und die sich daraus ergebende Nutzbarkeit des Heckbereichs als Ladefläche wird die Ladekapazität des Binnenschiffes signifikant erhöht. Da das Binnenschiff typischerweise im Heckbereich die größte Breite aufweist, stellt dieser Bereich eine besonders wertvolle Ladefläche dar, da dort auch große Frachtstücke wie Container in großer Zahl untergebracht werden können.Thus, the drive shafts can be arranged with the electric drives in the rear of the ship, while the generators can be arranged in the bow area. Since the generators are thus displaced out of the rear area as large-volume power supply units, this freed-up rear area is available as a loading area for freight to be loaded. In all inland vessels, the tail area is considerably wider than the forward narrow tapered bow area. Due to the inventive displacement of the generators as energy supply units in the bow area and the resulting usability of the rear area as a loading area, the loading capacity of the inland vessel is significantly increased. Since the inland vessel typically has the greatest width at the rear, this represents Area is a particularly valuable cargo area, since there can be housed large items such as containers in large numbers.

Das modulare Konzept des erfindungsgemäßen Antriebssystems kann dadurch besonders vorteilhaft ausgeprägt sein, dass eine oder alle Antriebswellen mit den daran angeordneten Propellern und elektrischen Antrieben eine vormontierte, mechanische Baueinheit bilden. Dabei sind zweckmäßig die elektrischen Antriebe auf Fundamenten gelagert.The modular concept of the drive system according to the invention can be particularly advantageous characterized in that one or all drive shafts with the propellers and electric drives arranged thereon form a preassembled mechanical unit. In this case, the electric drives are expediently mounted on foundations.

Die so gebildeten modularen Einheiten können rationell gefertigt werden und können zudem besonders einfach und schnell an geeigneten Einbauorten im Schiff installiert werden.The modular units thus formed can be produced efficiently and can also be installed particularly easily and quickly at suitable installation locations in the ship.

Dasselbe gilt für die Generatoren, die ebenfalls auf Fundamenten gelagerte, vormontierte Einheiten bilden können.The same applies to the generators, which can also form pre-assembled units stored on foundations.

Ein weiterer Vorteil der Erfindung besteht darin, dass mit den Generatoren die Komponenten zur Energieversorgung der elektrischen Antriebe und auch die elektrischen Antriebe selbst redundant vorgesehen sind, so dass für das gesamte Antriebssystem eine hohe Ausfallsicherheit erzielt werden kann.Another advantage of the invention is that the components for the power supply of the electric drives and also the electric drives themselves are provided redundantly with the generators, so that a high reliability can be achieved for the entire drive system.

Zur Erzielung dieser erhöhten Ausfallsicherheit weisen die Steuermittel des Antriebssystems bevorzugt eine zentrale Steuereinheit auf. In dieser Steuereinheit kann zweckmäßigerweise eine Ausfall- und/oder Fehlerkontrolle von Komponenten des Antriebssystems erfolgen, so dass in Abhängigkeit dieser Kontrolle die Generatoren und elektrischen Antriebe gesteuert, bevorzugt aktiviert oder deaktiviert werden. Zur Gewährleistung einer fehlersicheren Kontrollfunktion kann dabei die Steuereinheit selbst redundant, das heißt fehlersicher ausgelegt sein.To achieve this increased reliability, the control means of the drive system preferably have a central control unit. A failure and / or error control of components of the drive system may expediently ensue in this control unit, so that the generators and electric drives are controlled, preferably activated or deactivated, as a function of this control. To ensure a fail-safe control function while the control unit itself redundant, that is designed to be fail-safe.

Besonders vorteilhaft erfolgt die Steuerung der Komponenten des Antriebssystems nicht nur derart, dass die Ausfallsicherheit des Antriebssystems gewährleistet ist. Vielmehr erfolgt die Steuerung auch derart, dass ein möglichst energieeffizienter Betrieb des Antriebssystems gewährleistet ist. Hierzu wird in Abhängigkeit der aktuell benötigten Antriebsleistung eine geeignete Anzahl von elektrischen Antrieben auf der oder jeder Antriebswelle aktiviert. Zudem wird entsprechend dem aktuellen Energiebedarf eine geeignete Anzahl von Generatoren aktiviert. Die vorzugsweise jeweils aus einem Dieselmotor und einem elektrischen Generator bestehenden Generatoren werden dabei derart selektiv aktiviert, dass diese in ihren optimalen Betriebspunkten betrieben werden können, so dass der Betrieb der Generatoren hinsichtlich deren Energieverbrauch und Leistungsabgabe optimiert ist.Particularly advantageous is the control of the components of the drive system not only in such a way that ensures the reliability of the drive system is. Rather, the control is also such that the most energy-efficient operation of the drive system is ensured. For this purpose, a suitable number of electric drives on the or each drive shaft is activated depending on the currently required drive power. In addition, a suitable number of generators is activated according to the current energy demand. The preferably each consisting of a diesel engine and an electric generator generators are selectively activated so that they can be operated at their optimum operating points, so that the operation of the generators is optimized in terms of their energy consumption and power output.

Figur 1 zeigt ein Ausführungsbeispiel des erfindungsgemäßen Antriebssystems 1 für ein Schiff. Bei dem Schiff handelt es sich um ein Binnenschiff, das als Frachtschiff ausgebildet ist. Das Antriebssystem 1 weist im vorliegenden Fall zwei Propeller 2 auf, wobei jeder Propeller 2 am Ende einer Antriebswelle 3 angeordnet ist. Die Propeller 2 sind im vorliegenden Fall identisch ausgebildet und weisen eine Anordnung von in regelmäßigen Winkeln zueinander angeordneten Propellerblättern 2a auf. FIG. 1 shows an embodiment of the drive system 1 according to the invention for a ship. The ship is an inland vessel, which is designed as a cargo ship. The drive system 1 has two propellers 2 in the present case, each propeller 2 being arranged at the end of a drive shaft 3. The propellers 2 are identical in the present case and have an array of propeller blades 2a arranged at regular angles to one another.

Zum Antrieb der Propeller 2 sind auf jeder Antriebswelle 3 zwei elektrische Antriebe 4 vorgesehen. Generell können auch mehrere elektrische Antriebe 4 auf einer Antriebswelle 3 vorgesehen sein. Die elektrischen Antriebe 4 einer Antriebswelle 3 bilden für den zugeordneten anzutreibenden Propeller 2 eine redundante Antriebseinheit. Die einzelnen elektrischen Antriebe 4 können identisch oder unterschiedlich ausgebildet sein. Vorzugsweise werden als elektrische Antriebe 4 Torquemotoren eingesetzt, die bei geringen Drehzahlen bereits hohe Drehmomente erzeugen. Zweckmäßig sind die elektrischen Antriebe 4 als Hohlwellenmotoren ausgebildet, die als Direktantriebe auf der Antriebswelle 3 angeordnet werden können. Wie aus Figur 2 ersichtlich, ist an jeder Antriebswelle 3 zwischen dem elektrischen Antrieb 4 und dem Propeller 2 eine Kupplung 5 vorgesehen. Jedem elektrischen Antrieb 4 ist ein Wechselrichter 6 vorgeordnet. Zwischen dem Propeller 2 und dem daran anschließenden elektrischen Antrieb 4 einer Antriebswelle 3 kann ein nicht dargestelltes Drehlager vorgesehen sein. Die elektrischen Antriebe 4 sind zweckmäßig in Fundamenten gelagert.To drive the propeller 2 3 three electric drives 4 are provided on each drive shaft. In general, several electric drives 4 can be provided on a drive shaft 3. The electric drives 4 of a drive shaft 3 form a redundant drive unit for the associated propeller 2 to be driven. The individual electric drives 4 may be identical or different. Preferably as electrical Drives 4 torque motors used, which already generate high torques at low speeds. Suitably, the electric drives 4 are designed as hollow shaft motors, which can be arranged as direct drives on the drive shaft 3. How out FIG. 2 can be seen, a clutch 5 is provided on each drive shaft 3 between the electric drive 4 and the propeller 2. Each electric drive 4 is preceded by an inverter 6. Between the propeller 2 and the subsequent electric drive 4 of a drive shaft 3, a pivot bearing, not shown, may be provided. The electric drives 4 are expediently stored in foundations.

Die Spannungsversorgung erfolgt über einen Gleichspannungszwischenkreis 7. Eine im Gleichspannungszwischenkreis 7 zur Verfügung gestellte Gleichspannung wird in den Wechselrichtern 6 in eine Wechselspannung mit einer für die elektrischen Antriebe 4 geeigneten Frequenz umgesetzt.The voltage is supplied via a DC voltage intermediate circuit 7. A DC voltage provided in the DC intermediate circuit 7 is converted in the inverters 6 into an AC voltage having a frequency suitable for the electric drives 4.

Die einzelnen elektrischen Antriebe 4 können über Schalter 8, die von einer nicht dargestellten Steuereinheit gesteuert werden, einzeln durch An- oder Abkoppeln vom Gleichspannungszwischenkreis 7 aktiviert oder deaktiviert werden.The individual electric drives 4 can be activated or deactivated individually by switching on or uncoupling from the DC intermediate circuit 7 via switches 8, which are controlled by a control unit, not shown.

Zur Generierung der Zwischenspannung im Gleichspannungszwischenkreis 7 sind vier Generatoren 9 vorgesehen. Generell kann auch eine andere Auswahl von mehreren Generatoren 9 vorgesehen sein, wobei diese generell identisch oder unterschiedlich ausgebildet sein können. Im vorliegenden Fall ist ein Generator 9 mit einer kleinen Leistung vorgesehen. Die drei anderen Generatoren 9 weisen dieselbe Leistung auf, wobei diese größer ist als die Leistung der ersten Generatoren 9. Die einzelnen Generatoren 9 bilden eine redundante Energieversorgungseinheit. Die Generatoren 9 bestehen jeweils aus einem Dieselmotor und einem elektrischen Generator 9. Jedem Generator 9 ist ein Wechselrichter 10 nachgeordnet. Mit dem Wechselrichter 10 werden in dem Generator 9 generierte Wechselspannungen in eine Gleichspannung transformiert und in den Gleichspannungszwischenkreis 7 eingespeist. Die Generatoren 9 sind jeweils über einen Schalter 11 dem Gleichspannungszwischenkreis 7 selektiv zuschaltbar. Die Steuerung des Schalters 11 erfolgt wieder über die Steuereinheit.To generate the intermediate voltage in the DC intermediate circuit 7 four generators 9 are provided. In general, another selection of a plurality of generators 9 may be provided, wherein these may be generally identical or different. In the present case, a generator 9 is provided with a small power. The three other generators 9 have the same power, which is greater than the power of the first generators 9. The individual generators 9 form a redundant power supply unit. The generators 9 each consist of a diesel engine and an electric generator 9. Each generator 9 is followed by an inverter 10. With the inverter 10 AC voltages generated in the generator 9 are transformed into a DC voltage and in the DC intermediate circuit 7 is fed. The generators 9 are each selectively switchable via a switch 11 to the DC voltage intermediate circuit 7. The control of the switch 11 is again via the control unit.

Figur 2 zeigt schematisch die Aufteilung der Komponenten des Antriebssystems 1 in unterschiedlichen Bereichen des Binnenschiffes. Der in Figur 2 mit I bezeichnete Bereich bildet den Heckbereich des Binnenschiffes. Dort sind die Antriebswellen 3 mit den Propellern 2 und den elektrischen Antrieben 4 angeordnet. Jede Antriebswelle 3 mit den dieser zugeordneten Komponenten bildet eine vorgefertigte und vorgeprüfte Baueinheit 12. In dieser Baueinheit 12 sind die elektrischen Antriebe 4 mit Fundamenten 13 auf einer Platte 14 oder einem Rahmengestell gelagert. Der Propeller 2 ist mittels eines Drucklagers 15 auf der Antriebswelle 3 angeordnet. Prinzipiell können beide Antriebswellen 3 mit den zugeordneten Komponenten eine Baueinheit 12 bilden. Durch die unmittelbare Anordnung dieser Baueinheiten 12 im Heckbereich und damit am Anbringungsort der Propeller 2 können die Längen der Antriebswelle 3 klein gehalten werden. FIG. 2 shows schematically the distribution of the components of the drive system 1 in different areas of the inland vessel. The in FIG. 2 I marked area forms the rear of the barge. There, the drive shafts 3 with the propellers 2 and the electric drives 4 are arranged. Each drive shaft 3 with its associated components forms a prefabricated and pre-tested unit 12. In this unit 12, the electric drives 4 are mounted with foundations 13 on a plate 14 or a frame. The propeller 2 is arranged on the drive shaft 3 by means of a thrust bearing 15. In principle, both drive shafts 3 with the associated components can form a structural unit 12. Due to the immediate arrangement of these units 12 in the rear area and thus at the mounting location of the propeller 2, the lengths of the drive shaft 3 can be kept small.

Im Maschinenraum, der in Figur 2 mit II bezeichnet ist, sind die einzelnen Generatoren 9 angeordnet. Die Generatoren 9 bilden ebenfalls auf Fundamenten 16 gelagerte vorgefertigte und vormontierte Baueinheiten. Der Maschinenraum befindet sich im Bugbereich des Binnenschiffes. Da somit die Generatoren 9 aus dem Heckbereich des Binnenschiffes herausverlagert sind, steht dieser Heckbereich als Ladefläche zur Verfügung. Im Heckbereich befinden sich zwar die modularen Einheiten mit den auf den Antriebswellen 3 angeordneten elektrischen Antrieben 4. Diese elektrischen Antriebe 4 weisen jedoch relativ kleine Bauformen auf und führen so zu keiner nennenswerten Reduzierung der Ladefläche im Heckbereich.In the engine room, in FIG. 2 denoted by II, the individual generators 9 are arranged. The generators 9 also form on foundations 16 stored prefabricated and pre-assembled units. The engine room is located in the bow area of the inland ship. Since thus the generators 9 are moved out of the rear of the barge, this rear area is available as a cargo area. Although the modular units with the electric drives 4 arranged on the drive shafts 3 are located in the rear area, these electric drives 4 have relatively small designs and thus do not lead to a significant reduction in the loading area in the rear area.

Im Bereich des Maschinenraums, vorzugsweise in einem von den Generatoren 9 abgeteilten, separaten Raum befindet sich eine Schaltanlage 17. Diese Schaltanlage 17 weist insbesondere Schaltschienen 18a, 18b mit den Schaltern 8, 11 zur Anschaltung der elektrischen Antriebe 4 beziehungsweise Generatoren 9 an den Gleichspannungszwischenkreis 7 auf. Auch die Komponenten des Gleichspannungszwischenkreises 7 sind in der Schaltanlage 17 integriert. Auch die Schaltanlage 17 bildet eine modulare Einheit und stellt eine vorgefertigte und vorgeprüfte Einheit dar.In the area of the engine room, preferably in a separate from the generators 9, separate room is a switchgear 17. This switchgear 17 has in particular switching rails 18a, 18b with the switches 8, 11 for connecting the electric drives 4 or generators 9 to the DC voltage intermediate circuit 7. The components of the DC intermediate circuit 7 are integrated in the switchgear 17. The switchgear 17 also forms a modular unit and represents a prefabricated and pre-tested unit.

In der Schaltanlage 17 sind vorteilhaft Schienentrenner oder ähnliche Schaltmittel vorgesehen, mittels derer die Anschaltung für die einzelnen Generatoren 9 und/oder elektrischen Antriebe 4 elektrisch separiert werden kann, wodurch voneinander getrennte Teilsysteme erhalten werden.In the switchgear 17 rail splitter or similar switching means are advantageously provided, by means of which the connection for the individual generators 9 and / or electric drives 4 can be electrically separated, whereby separate subsystems are obtained.

In Figur 2 ist mit III die Wohnraumebene, das heißt der sogenannte Accessoirbereich bezeichnet. In diesem Bereich befindet sich eine Anordnung von SPS-Steuerungen 19, die die zentrale Steuereinheit des Binnenschiffes bildet. Diese sind an die Schaltanlage 17 angeschlossen.In FIG. 2 III is the residential area level, ie the so-called accessory area. In this area is an array of PLC controls 19, which forms the central control unit of the inland vessel. These are connected to the switchgear 17.

Schließlich ist in Figur 2 mit IV der Bereich der Brücke des Binnenschiffes dargestellt. Hier sind in bekannter Weise von Bedienpersonen bedienbare Mittel zur Lenkung und Steuerung des Schiffes vorgesehen, insbesondere ein Telegraph 20 mit welchem die SPS-Steuerungen 19 angesteuert werden.Finally, in FIG. 2 represented with IV the area of the bridge of the inland vessel. Here are operated in a known manner by operators operable means for steering and control of the ship, in particular a telegraph 20 with which the PLC controls 19 are controlled.

Die Stromversorgung der SPS-Steuerungen 19 und des gesamten Bordnetzes erfolgt über die Generatoren 9. Hierfür sind geeignete Anschaltungen in den Schaltschienen 18a, 18b vorgesehen.The power supply of the PLC controls 19 and the entire electrical system via the generators 9. For this purpose, suitable interfaces in the shift rails 18a, 18b are provided.

Das Binnenschiff wird im vorliegenden Fall in vier unterschiedlichen Modes betrieben. Der erste Mode bildet die sogenannte Bergfahrt des Schiffs bei voller Beladung. In diesem Fall beträgt der Leistungsbedarf etwa 80 % der von den Generatoren 9 bereitstellbaren Leistung. In diesem Mode werden mittels der Steuereinheit 12 die drei Generatoren 9 mit hoher Leistung aktiviert, während der Generator 9 mit kleiner Leistung deaktiviert ist.The inland waterway vessel is operated in four different modes in the present case. The first fashion is the so-called ascent of the ship at full load. In this case, the power requirement is about 80% of the power that can be provided by the generators 9. In this mode, the three generators 9 are activated by means of the control unit 12 with high power, while the generator 9 is deactivated with low power.

Bei dem zweiten und dritten Mode (Talfahrt mit oder ohne Beladung) beträgt der Leistungsbedarf etwa 50 % beziehungsweise 35 % der maximal verfügbaren Leistung. Um diese Leistungen zur Verfügung zu stellen, werden zweckmäßig zwei der Generatoren 9 mit der größeren Leistung aktiviert, während die restlichen Generatoren 9 deaktiviert sind.In the second and third modes (deceleration with or without loading), the power requirement is about 50% and 35% of the maximum available power. In order to provide these services, two of the generators 9 with the larger power are expediently activated while the remaining generators 9 are deactivated.

Schließlich wird bei dem vierten Mode (Kanalfahrt), bei dem nur etwa 10 % der maximalen Leistung benötigt wird, nur der Generator 9 mit der kleineren Leistung aktiviert, während die übrigen Generatoren 9 deaktiviert sind.Finally, in the fourth mode (channel travel), where only about 10% of the maximum power is needed, only the smaller power generator 9 is activated while the other generators 9 are deactivated.

Durch die selektive Zuschaltung einzelner Generatoren 9 in den einzelnen Modes kann die Generatorleistung an die aktuell benötigte Leistung angepasst werden. Durch diese Leistungsanpassung können die jeweils aktivierten Generatoren 9 in ihren optimalen Arbeitspunkten betrieben werden. Durch die Ausnutzung der optimalen Arbeitspunkteinstellung der Generatoren 9 ergibt sich eine signifikante Energieeinsparung gegenüber Schiffen, deren Generatoren 9 nicht im optimalen Arbeitspunkt betrieben werden können.Through the selective connection of individual generators 9 in the individual modes, the generator power can be adapted to the currently required power. Through this power adjustment, the respective activated generators 9 can be operated at their optimum operating points. By exploiting the optimum operating point setting of the generators 9 results in a significant energy savings compared to ships whose generators 9 can not be operated at the optimum operating point.

Bei sämtlichen Modes des Schiffes ist zumindest ein Generator 9 deaktiviert. Vorteilhaft ist auch immer ein elektrischer Antrieb 4 pro Antriebswelle 3 deaktiviert.In all modes of the ship at least one generator 9 is deactivated. Advantageously, an electric drive 4 per drive shaft 3 is always deactivated.

Diese im regulären Betrieb des Schiffes nicht genutzten Einheiten werden für eine mittels der Steuereinheit 12 durchgeführte Überwachung zur Ausfallsicherung des Antriebssystems 1 genutzt. Bei dieser Überwachung überprüft die Steuereinheit 12 fortlaufend die Funktion der angeschlossenen Einheiten, insbesondere aller elektrischen Antriebskomponenten. Wird ein Fehler oder ein Ausfall wenigstens einer dieser Komponenten registriert, wird ein Alarmsignal generiert. Vorteilhaft wird bei Auftreten des Alarmsignals das Antriebssystem 1 durch die Steuereinheit 12 selbsttätig in einen sicheren Zustand überführt.These unused in the regular operation of the ship units are used for a performed by the control unit 12 monitoring failover of the drive system 1. In this monitoring, the control unit 12 continuously checks the function of the connected units, in particular all electric drive components. If an error or a failure of at least one of these components is registered, an alarm signal is generated. Advantageously, when the alarm signal occurs, the drive system 1 is automatically transferred by the control unit 12 into a safe state.

Ist beispielsweise auf einer Antriebswelle 3 ein elektrischer Antrieb 4 ausgefallen, wird dies von der Steuereinheit 12 detektiert, worauf durch Betätigen der Schalter 8 der defekte elektrische Antrieb 4 vom Gleichspannungszwischenkreis 7 abgekoppelt und ein intakter elektrischer Antrieb 4 auf dieser Antriebswelle 3 dadurch aktiviert wird, dass der zugeordnete Schalter 8 geschlossen ist. Das Antriebssystem 1 ist damit wieder voll funktionsfähig.If, for example, an electric drive 4 has failed on a drive shaft 3, this is detected by the control unit 12, whereupon the defective electric drive 4 is decoupled from the DC voltage intermediate circuit 7 by actuation of the switches 8 and an intact electric drive 4 is activated on this drive shaft 3 by the associated switch 8 is closed. The drive system 1 is thus fully functional again.

Ist einer der im Betrieb befindlichen Generatoren 9 ausgefallen, so wird auch dies von der Steuereinheit 12 detektiert und durch Betätigen der Schalter 11 wird der defekte Generator 9 vom Gleichspannungszwischenkreis 7 abgekoppelt und ein intakter, bisher nicht aktivierter Generator 9 an den Gleichspannungszwischenkreis 7 angekoppelt.If one of the operating generators 9 has failed, this is also detected by the control unit 12 and by operating the switch 11, the defective generator 9 is decoupled from the DC intermediate circuit 7 and an intact, previously not activated generator 9 is coupled to the DC voltage intermediate circuit 7.

Hierbei ist vorteilhaft, dass in allen vier Betriebsmodes des Binnenschiffs immer zumindest ein Generator 9 nicht aktiviert ist. Damit kann, unabhängig davon, welcher Typ von Generator 9 in welchem Betriebsmode ausfällt, der bislang deaktivierte Generator 9 den jeweils ausgefallenen Generator 9 ersetzen, so dass das Antriebssystem 1 wieder voll funktionsfähig ist.It is advantageous that in all four operating modes of the inland ship always at least one generator 9 is not activated. Thus, regardless of which type of generator 9 fails in which operating mode, the previously deactivated generator 9 replace the respective failed generator 9, so that the drive system 1 is fully functional again.
