Description
Die vorliegende Erfindung betrifft ein Verfahren und ein System zur Bereitstellung der elektrischen Leistung an dezentralen Feldelementen eines Eisenbahnnetzwerkes.The present invention relates to a method and system for providing electrical power to distributed field elements of a railway network.
Derartige dezentrale Feldelementen werden in Schienenverkehrsnetzwerken genutzt, um die Schienenfahrzeuge beeinflussende und/oder die Schienenfahrzeuge überwachende Einheiten zu steuern und bezüglich der Funktionalität zu überwachen und um Prozessdaten aufzunehmen und zurück zu melden. Als zugbeeinflussende Einheiten, die also Anweisungen an den Fahrzeugführer geben oder sogar direkt Eingriffe in der Fahrzeugsteuerung vornehmen oder direkt einen sicheren Fahrweg einstellen, können beispielsweise Signale, Weichen, Balisen, Linienleiter, Gleismagnete und dergleichen sowie auch Sensoren zum Erfassen von Prozessgrössen des fahrenden Zuges, wie Leistungsaufnahme, Geschwindigkeit und dergleichen, betrachtet werden. Als Zug- und Gleisabschnitt überwachende Einheiten können ebenfalls Balisen und Linienleiter, aber auch Achszähler und Gleisstromkreise genannt werden.Such decentralized field elements are used in rail transport networks to control the rail vehicles influencing and / or the rolling stock monitoring units and to monitor the functionality and to record and report back process data. As Zugbeeinflussende units that give instructions to the driver or even make direct intervention in the vehicle control or directly set a safe track, for example, signals, points, balises, line conductors, track magnets and the like, as well as sensors for detecting process variables of the moving train, such as power consumption, speed and the like. As train and track section monitoring units can also be called balises and line conductors, but also axle counters and track circuits.
Im Eisenbahnverkehr ist es üblicherweise so, dass diese dezentralen Feldelemente von einem Stellwerk oder einem abgesetzten Stellrechner gesteuert werden. Für den Datentransfer zwischen dem Stellwerk und den Feldelementen im Gleisbereich sind heute in der Regel standardisierte Kupferkabel vorgesehen, für deren klassische Stelldistanzlängen wegen der physikalischen Übertragungsparameter, den Kabelbelägen (RLC), bei 10 km in der Praxis die obere Grenze liegt. Bei gewissen Typen von Feldelementen kann diese obere Limite jedoch auch nur bei maximal 6,5 km liegen.In railway traffic, it is usually the case that these decentralized field elements are controlled by an interlocking or a remote control computer. For the data transfer between the interlocking and the field elements in the track area today standardized copper cables are usually provided, for their classical travel distances because of the physical transmission parameters, the cable coverings (RLC), at 10 km in practice is the upper limit. For certain types of Field elements, this upper limit, however, can only be at a maximum of 6.5 km.
Gemäss der europäischen Patentanmeldung
- a) ein übergeordnetes Steuerungssystem, das mit den dezentralen Feldelementen mittels Datentelegrammen Informationen austauscht,
- b) ein Datentransportnetzwerk mit einer Anzahl von Netzzugangspunkten, wobei das übergeordnete Steuerungssystem über mindestens einen Netzzugangspunkt an dem Datentransportnetzwerk angekoppelt ist;
- c) Kommunikationseinheiten, die jeweils an einem Netzzugangspunkt angeschlossen sind, wobei:
- d) die dezentralen Feldelementen zu Untergruppen mit jeweils eigenem Subnetzwerk zusammengefasst sind; und wobei
- e) das Subnetzwerk jeder der Untergruppen an jedem seiner beiden Ende jeweils über eine Kommunikationseinheit und über einem Netzzugangspunkt an dem Datentransportnetzwerk angekoppelt ist.
- a) a higher-level control system which exchanges information with the decentralized field elements by means of data telegrams,
- b) a data transport network having a number of network access points, wherein the higher-level control system is coupled to the data transport network via at least one network access point;
- c) communication units each connected to a network access point, wherein:
- d) the decentralized field elements are combined into subgroups, each with its own subnetwork; and where
- e) the subnetwork of each of the subgroups at each of its two ends is coupled to the data transport network via a communication unit and via a network access point.
Auf diese Weise kann für die Ankopplung der dezentralen Feldelementen ein digitales Transportnetzwerk genutzt werden, welches in jeder Weise robust gegen ein einfaches Fehlerereignis ist, dennoch eine sehr geschickte Verwendung von sehr breit in der Bahntechnik eingesetzten Cu-Kabeln, zum Beispiel bisher vorhandenen Stellwerkskabeln, erlaubt und schliesslich auch nur eine vergleichsweise geringe Zahl von Netzzugangspunkten benötigt. Diese Lösung wird beispielsweise unter dem Namen SiNet® von der Siemens Schweiz AG vertrieben.In this way, a digital transport network can be used for the coupling of the decentralized field elements, which is robust in every way against a simple error event, yet a very clever use of very widely used in railway engineering Cu cables, for example, previously existing interlocking cables allowed and finally only a comparatively small number of network access points needed. This solution is sold, for example, under the name SiNet® by Siemens Switzerland AG.
Im Rahmen der Fortbildung dieses Projekts soll nun auch die elektrische Spannungsversorgung von dezentralen Feldelementen zunehmend nicht mehr aus dem Stellwerk heraus geleistet, sondern mit Hilfe des Einsatzes eines vom Stellwerk komplett unabhängigen Spannungsversorgungsnetzes gelöst werden.As part of the training of this project, the electrical power supply of decentralized field elements is now increasingly no longer made from the interlocking, but are solved by using a completely independent power supply network from the interlocking.
Hierbei sind gemäss der europäischen Patentanmeldung
Gemäss diesem neuen Konzept gehen einem Stellwerkrechner für die gleichen dezentralen Feldelemente dann nur noch vier Kabeladern für die elektrische Energie und bis zu vier Kabeladern für die Kommunikation heraus. Dabei ist der Stellwerkrechner ebenfalls über einen Netzzugangspunkt an dem Datentransportnetz angeschlossen.According to this new concept, only four cable cores for electrical energy and up to four cable cores for communication go out of one interlocking computer for the same decentralized field elements. The interlocking computer is also connected via a network access point to the data transport network.
Auf diese Weise ergibt sich eine hinsichtlich der verwendeten dezentralen Feldelemente und der intelligenten Energiespeicher eine skalierbare Situation im Gleisbereich. Dabei können auch skalierbare Leitungsmodelle und skalierbare Energiespeicher eingesetzt werden. Als Energiespeicher können dabei auch mechanische Schwungradspeicher und Super-Kondensatoren eingesetzt werden. Diese Lösung zeigt daher auch den Nutzen dieses Konzepts der dezentral verteilt angeordneten Energiespeicher im Energietransportnetz auf, sodass die Auslegung des Energietransportnetzes den Beitrag der Energiespeicher dahingehend nutzen kann, dass die Leitungsadern des Netzwerks nur für eine vorbestimmbare Basisleistung ausgelegt werden müssen.This results in a scalable situation in the track area with regard to the decentralized field elements used and the intelligent energy storage device. Scalable cable models and scalable energy storage can also be used. As energy storage and mechanical flywheel storage and super capacitors can be used. Therefore, this solution also shows the benefit of this concept of decentrally distributed energy storage in the energy transport network, so that the design of the energy transport network can use the contribution of the energy storage to the effect that the wires of the network must be designed only for a predeterminable basic performance.
Wie aus dieser Lösung nachvollziehbar, benötigen dabei besonders Weichen- und Schrankenantriebe kurzfristig relativ grosse Leistungen, deren Bereitstellung unter Zuhilfenahme der Speicherelement so erzielt werden soll, dass die über das Netz bereitgestellte Leistung eine gewisse Grundlast dauerhaft bereitstellt, die ausreichend ist, um die Speicherelemente periodisch wieder zur Bereitstellung der Spitzenlast aufladen zu können. Die Auslegung der Kapazität der Speicherelemente sowie der Kapazität des die Grundlast bereitstellenden Netzes sind jedoch recht komplex, da hierzu derzeit keinerlei verlässliche Planungsgrundlagen existieren.As can be understood from this solution, especially turnout and barrier drives require relatively high power in the short term, the provision of which is to be achieved with the aid of the memory element so that the power provided via the network permanently provides a certain base load, which is sufficient to the storage elements periodically recharge to provide the peak load. The design of the capacity of the storage elements as well as the capacity of the base load However, the provisioning network is quite complex, as there are currently no reliable planning foundations.
Das vorstehend genannte Problem wurde bisher noch nicht gelöst, weil das Konzept des vom Stellwerk entkoppelten Spannungsversorgungsnetzwerks bisher im Bahnbereich noch nicht umgesetzt worden ist und einen regelrechten Paradigmenwechsel darstellt, weil viele dezentrale Feldelemente nun nicht mehr durch die direkte Überwachung der elektrischen Leistungsaufnahme aus dem Stellwerk her überwacht werden können.The above problem has not yet been solved because the concept of decoupled from the interlocking power supply network has not yet been implemented in the railway sector and is a veritable paradigm shift, because many decentralized field elements now no longer by the direct monitoring of electrical power consumption from the interlocking ago can be monitored.
In der
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein System und ein Verfahren zur Bereitstellung der elektrischen Leistung an dezentralen Feldelementen eines Eisenbahnnetzwerkes anzugeben, mit denen im Wege einer Grundversorgung eine Grundlast abgedeckt und Speicherelemente so aufgeladen werden können, dass diese die erforderliche Spitzenlast im Bedarfsfall bereitstellen können.The present invention is therefore based on the object of specifying a system and a method for providing the electrical power to decentralized field elements of a railway network, with which a base load covered by means of a basic supply and storage elements can be charged so that they provide the required peak load when needed can.

Bezüglich des Systems wird diese Aufgabe erfindungsgemäss durch ein System zur Bereitstellung der elektrischen Leistung an dezentralen Feldelementen eines Eisenbahnnetzwerkes gelöst, welches die folgenden Komponenten umfasst:
- a) Mittel zum Zuordnen der Leistungsaufnahme der dezentralen Feldelemente zu vorbestimmten Verbrauchsklassen;
- b) Mittel zum Aufsummieren der in einem Streckenabschnitt des Eisenbahnnetzwerks angeordneten dezentralen Feldelemente hinsichtlich ihrer den Verbrauchsklassen zugeordneten Leistungsaufnahme für die Einstellung einer ersten fahrplangemässen Fahrstrasse, wobei von einer eingestellten Grundfahrstrasse ausgegangen wird,

Auf diese Weise ergibt sich eine vorausschauende skalierte Prognose der Leistungsaufnahme von elektrischen Feldelementen aufgrund der mittels des Fahrplans prognostizierbaren Belegung des Gleiskörpers. Zunächst wird dabei einmal bestimmt, welche Anzahl von Leistungsverbrauchern (Signallampen, Weichenantriebe, Schrankenantriebe, Achszählpunkte, Gleisstromkreise, Balisen, Linienleiter und dergleichen) mit welchen Leistungsklassen im Gleisnetz angeordnet sind. Dabei wird auch die exakte Lage der Feldelemente bestimmt und diese bestimmten Fahrstrassen zugeordnet.In this way, a forward-looking scaled forecast of the power consumption of electric field elements results from the track plan's predictable occupancy of the track body. First of all, it is determined which number of power consumers (signal lamps, turnout drives, barrier drives, axle counting points, track circuits, balises, line conductors and the like) are arranged with which power classes in the track network. In this case, the exact position of the field elements is determined and assigned to specific routes.
Anhand des Fahrplans kann nun ganz exakt bestimmt werden, welche Züge den jeweiligen Streckenabschnitt unter Benutzung vorbestimmter Fahrstrassen benutzen werden. Bei der Projektierung der Fahrstrassen kann dann auch genau bestimmt werden, welche Feldelemente bei einem Wechsel von einer n-ten Fahrstrasse zur (n+1)-ten Fahrstrasse aktiviert werden müssen und welche Feldelemente innerhalb des Streckenabschnitts (Blockabschnitt) unabhängig von der jeweils eingestellten Fahrstrasse periodisch oder dauerhaft betrieben werden müssen. Im Rahmen dieser Projektierung wird den einzelnen dezentralen Feldelementen eine normierte Energie-/Leistungsaufnahme(klasse) zugeordnet, sodass für einen Streckenabschnitt die bereitzustellende Energie/Leistung im Rahmen dieser Projektierung zeitlich und räumlich aufgelöst relativ genau bestimmt werden kann.Based on the timetable can now be determined exactly which trains will use the respective route section using predetermined routes. In the Configuration of the routes can then also be determined exactly which field elements must be activated at a change from an n-th road to the (n + 1) -th road and which field elements within the section (block section) regardless of the selected route road periodically or must be operated permanently. In the context of this project planning, a standardized energy / power consumption (class) is assigned to the individual decentralized field elements, so that the energy / power to be provided can be determined relatively accurately in terms of time and space in the course of this project.
Mittels dieser Projektierungsdaten wird dann das elektrische Versorgungsnetz hinsichtlich der Grundlast und der einzusetzenden Speicherelemente sowie des distinkten Ortes dieser Speicherelemente projektiert und entsprechend erstellt. Der Fahrbetrieb wird anschliessend mit diesem Spannungsversorgungsnetzwerk für die in dem betreffenden Streckenabschnitt angeordneten dezentralen Feldelemente durchgeführt.By means of this configuration data, the electrical supply network is then configured with regard to the base load and the storage elements to be used as well as the distinct location of these storage elements and created accordingly. The driving operation is then carried out with this power supply network for the decentralized field elements arranged in the relevant road section.
Die vorliegende Erfindung führt daher im Ergebnis zu einer Skalierung der Leistungsaufnahme und liefert aufgrund der mittels des Fahrplans prognostizierbaren Streckenbelegung ein normatives Werkzeug, aus dem gezielt zeitlich und räumlich aufgelöste Profile der elektrischen Leistungsaufnahme ableitbar sind. Mit Hilfe dieser Profile werden die elektrische Grundlast, die Spitzenlast sowie die Kapazität und der physische Ort der Energiespeicher festgelegt. Auf diese Weise ergibt sich ein sehr detailliert vorausplanbares Models/Profil der elektrischen Leistungsaufnahme, welche später entsprechend dieses Modells/Profils bereitgestellt werden kann. Damit ist das Leistungsversorgungsnetzwerk effizient und anforderungsgerecht auslegbar, wodurch ein schonender Umgang mit Ressourcen, wie Kupferkabeln, Energiespeichermaterialien erreicht werden kann.As a result, the present invention results in a scaling of the power consumption and, on the basis of the route allocation which can be predicted by means of the timetable, provides a normative tool from which specifically timed and spatially resolved profiles of the electrical power consumption can be derived. These profiles are used to determine the base electric load, the peak load and the capacity and physical location of the energy storage devices. In this way results in a very detailed predictable models / profile of electrical power consumption, which can be provided later according to this model / profile. That's it Power supply network can be interpreted efficiently and according to requirements, whereby a careful handling of resources, such as copper cables, energy storage materials can be achieved.
In einer vorteilhaften Ausgestaltung der vorliegenden Erfindung kann es vorgesehen sein, mindestens zwei Verbrauchsklassen zu definieren, wobei die erste Verbrauchsklasse dezentralen Feldelemente mit niedrigem und eher permanenten Leistungsbedarf repräsentiert und die zweite Verbrauchsklasse dezentrale Feldelemente mit vergleichsweise hohem, aber kurz andauernden Leistungsbedarf repräsentiert. Dezentrale Feldelemente mit niedrigem und eher permanentem Leistungsbedarf sind zum Beispiel Lichtsignale, Balisen, Achszähler, Gleisstromkreise und ihre jeweiligen Steuerungseinrichtungen (sogenannte LEU's-Lineside Electronic Equipment). Dezentrale Feldelemente mit vergleichsweise hohem, aber nur kurz andauerndem Leistungsbedarf sind zum Beispiel die Weichenantriebe und Barrierenantriebe und ihre jeweiligen Steuerungseinrichtungen.In an advantageous embodiment of the present invention, it may be provided to define at least two consumption classes, the first consumption class representing decentralized field elements with low and rather permanent power requirements and the second consumption class representing decentralized field elements having comparatively high, but short-lasting power requirements. Decentralized field elements with low and rather permanent power requirements are, for example, light signals, balises, axle counters, track circuits and their respective control devices (so-called LEU's-Lineside Electronic Equipment). Decentralized field elements with comparatively high but short-lasting power requirements are, for example, the point machines and barrier drives and their respective control devices.
Im Besonderen durch Verspätungen oder durch Sonderereignisse, wie z.B. grosse Messen, Konzerte oder Sportveranstaltungen, kann eine temporäre Abweichung des ermittelten räumlich und/oder zeitlich aufgelösten Verbrauchsprofils auftreten. Um diesen Mehrbedarf gegebenenfalls mit den vorhandenen Mitteln auffangen zu können, kann es vorgesehen sein, dass die bereitgestellte Leistung eine Reserveleistung umfasst, die etwa 20 bis 60 Prozent des Leistungsbedarfs des räumlich und/oder zeitlich aufgelösten Verbrauchsprofils beträgt. Damit wird der Fall temporärer Abweichungen vom Verbrauchsprofil in der Regel zu beherrschen sein. Sollte die bereitstellbare Energiemenge allerdings vom tatsächlichen Bedarf überstiegen werden, könnte beispielsweise die Reserveleistung eines angrenzenden Streckenabschnitts oder eine weitere Energiequelle, wie z.B. eine Leitung des öffentlichen Netzes oder der Fahrdraht, temporär angezapft werden.In particular, by delays or by special events, such as large fairs, concerts or sporting events, a temporary deviation of the determined spatially and / or temporally resolved consumption profile may occur. In order to be able to absorb this additional demand with the available funds, it may be provided that the provided power comprises a reserve power which amounts to approximately 20 to 60 percent of the power requirement of the spatially and / or temporally resolved consumption profile. Thus, the case of temporary deviations from the consumption profile will usually have to be mastered. Should the amount of available energy However, for example, if the reserve power of an adjacent line segment or another source of energy, such as a public network line or trolley wire, could be tapped temporarily.
Zur Erleichterung der Projektierung kann es vorgesehen sein, dass die einsetzbaren Energiespeicher hinsichtlich der durch sie zur Verfügung stellbaren Energiemenge Leistungsklassen zugeordnet sein können. In vorteilhafter Weiterbildung dieser Ausgestaltung kann eine Konkordanzliste vorgesehen sein, die den Verbrauchsklassen entsprechende Energiespeicher geeigneter Leistungsklasse gegenüberstellt. Auf diese Weise ergibt sich eine Projektierbarkeit quasi nach dem System eines Baukastens, die so auch vorzugsweise programmierbar ist, wodurch ein projektiertes Layout beispielsweise mit einer entsprechenden Software automatisch erstellbar wäre. Allfällige Anpassungen könnten dann von Hand in diesem Layout projektiert werden.To facilitate the configuration, provision may be made for the usable energy stores to be assigned power classes with regard to the amount of energy that can be provided by them. In an advantageous embodiment of this embodiment, a concordance list can be provided which compares the consumption classes corresponding energy storage suitable performance class. In this way, a projectability quasi results according to the system of a modular system, which is also preferably programmable, whereby a projected layout would be automatically created, for example, with appropriate software. Any adjustments could then be configured by hand in this layout.

In der Grundstellung für diesen Streckenabschnitt 2 bestehen zwei nicht-abgelenkte Grundfahrstrassen, d.h. Einfahrt des Zuges bei Achszähler AZ1 und Ausfahrt bei Achszähler AZ3 und umgekehrt sowie Einfahrt des Zuges bei Achszähler AZ4 und Ausfahrt bei Achszähler AZ2 und umgekehrt. Eine erste davon abweichende Fahrstrasse F1 sieht die Einfahrt des Zuges bei Achszähler AZ1 und die Ausfahrt bei Achszähler AZ5 vor. Eine zweite von der Grundfahrstrasse abweichende Fahrstrasse F2 sieht die Einfahrt des Zuges bei Achszähler AZ6 und die Ausfahrt bei Achszähler AZ2 vor. Eine dritte von der Grundfahrstrasse abweichende Fahrstrasse F3 sieht die Einfahrt des Zuges bei Achszähler AZ2 und die Ausfahrt bei Achszähler AZ5 vor.

Die vier vorstehend genannten Fahrstrassen F1 bis F4 können dabei selbstverständlich auch in umgekehrter Richtung befahren werden.In the basic position for this
Zur elektrischen Spannungsversorgung sämtlicher dezentraler Feldelemente, worunter im vorliegenden Text die zugsichernde und zugbeeinflussende Einheit sowie deren Elementkontroller verstanden wird, erfolgt mittels eines Energiebusses EB. An diesen Energiebus EB sind sämtliche dezentrale Feldelemente angeschlossen.For the electrical power supply of all decentralized field elements, which is understood in the present text, the zugsichernde and zugbeeinflussende unit and the element controller, by means of a power bus EB. All decentralized field elements are connected to this energy bus EB.
Zur Projektierung des Energiebusses EB ist es besonders vorteilhaft zu wissen, welche elektrischen Leistungen zu welcher Zeit von dem Energiebus EB bereitzustellen sind. Besonders in entlegenen Gegenden kann auf diese Weise bestimmt werden, ob gewisse lokal vorhandene Spannungsversorgungsquellen angezapft werden können oder ob zusätzliche, aber in Regel teure Massnahmen zur Bereitstellung von mehr elektrischer Leistung erforderlich sind.For configuring the power bus EB, it is particularly advantageous to know which electrical powers are to be provided by the power bus EB at which time. Especially in remote areas can be determined in this way, whether certain locally available power sources can be tapped or additional, but usually expensive measures to provide more electrical power required.
Aus diesem Grund ist es zunächst in diesem Ausführungsbeispiel vorgesehen, für die dezentralen Feldelemente zwei Verbrauchsklassen EK1 und EK2 zu definieren, wobei die erste Verbrauchsklasse EK1 dezentralen Feldelemente mit niedrigem und eher permanenten Leistungsbedarf, wie z.B. die Achszähler AZ1 bis AZ6, die Balisen B1 bis B6 und die Signale S1 bis S6 repräsentiert und die zweite Verbrauchsklasse EK2 dezentrale Feldelemente mit vergleichsweise hohem, aber kurz andauernden Leistungsbedarf, wie z.B. den Bahnübergang BÜ und die Weichen W1 bis W4, repräsentiert. Der Energieklasse EK1 kann daher eine mittlere permanente Leistungsaufnahme von 50 Watt, d.h. über ein ganzen Tag gesehen eine Energiemenge von 1,2 kWh, und der Energieklasse EK2 ein kurzzeitiger Leistungsbedarf von 6 kW für eine Zeitdauer von jeweils maximal einer Minute, also ein Energiebedarf von jeweils 0,06 kWh, zugeordnet werden.For this reason, it is initially provided in this embodiment, for the decentralized field elements to define two consumption classes EK1 and EK2, wherein the first consumption class EK1 decentralized field elements with low and rather permanent power requirements, such as the axle counter AZ1 to AZ6, the balises B1 to B6 and represents the signals S1 to S6 and the second consumption class EK2 decentralized field elements with comparatively high, but short-lasting power requirements, such as the level crossing BÜ and the points W1 to W4 represented. The energy class EK1 can therefore a mean permanent power consumption of 50 watts, ie seen over a whole day an amount of energy of 1.2 kWh, and the energy class EK2 a short-term power requirement of 6 kW for a period of one minute maximum, ie an energy requirement of 0.06 kWh each.
Unter der Annahme, dass die Achszähler AZ1 bis AZ6, die Balisen B1 bis B6 und die Signale S1 bis S6 permanent eingeschaltet sind, ergibt sich so für diesen Streckenabschnitt eine durchschnittliche Leistungsaufnahme von 900 Watt, was einer täglichen Energiemenge von 21,6 kWh entspricht. Eine derartige Leistung könnte beispielsweise (ohne Berücksichtigung von Leitungsverlusten) bereits durch eine mit 10 Ampere abgesicherte Leitung 8 mit 220 VAC mit entsprechender Reserve bereitgestellt werden.Assuming that the axle counters AZ1 to AZ6, the beacons B1 to B6 and the signals S1 to S6 are permanently switched on, this section results in an average power consumption of 900 watts, which corresponds to a daily amount of energy of 21.6 kWh. For example, such power could already be provided (without consideration of line losses) by a 10 amp HW line 220VAC with appropriate reserve.
Unter der Annahme folgender Streckenbelegung lässt sich dann auch die Leistungsaufnahme der dezentralen Feldelemente mit der Energieklasse EK2 abschätzen:
- Es verkehren von 5 Uhr bis 24 Uhr vier Züge stündlich auf jeder der beiden Grundfahrstrassen. Zusätzlich verkehrt in dieser Zeit pro Stunde je ein Zug auf der Fahrstrasse F1 und auf der Fahrstrasse F2. Die Fahrstrassen F3 und F4 werden im Regelbetrieb nicht genutzt. Dies bedeutet, dass der Bahnübergang BÜ in 19 Stunden pro Stunde 10-mal geschlossen und wieder geöffnet wird, was insgesamt über den Zeitraum der 19 Stunden
einer Energiemenge von 22,8 kWh entspricht. Zusätzlich laufen die beiden Weichen W2 und W3 pro Stunde zweimal um, was ingesamt über den Zeitraum von 19 Stundeneiner Energiemenge von 2,28 kWh entspricht. Damit benötigen die dezentralen Feldelemente mit der zweiten Energieklasse EK2 pro Tag eine Energiemenge von 25,08 kWh.
- There are four trains every hour from 5 am to midnight on each of the two basic routes. In addition, there is one train per hour per hour on the F1 road and on the F2 road. The routes F3 and F4 are not used in normal operation. This means that the level crossing BÜ is closed and reopened 10 times in 19 hours per hour, which corresponds to a total energy amount of 22.8 kWh over the 19-hour period. In addition, the two switches W2 and W3 run twice per hour, which corresponds to a total of 2.28 kWh over a period of 19 hours. Thus, the decentralized field elements with the second energy class EK2 require an energy quantity of 25.08 kWh per day.
Diese Energiemenge kann mit der oben bereits genannten Leitung 8 (220VAC, 10A) nicht zusätzlich zu der für die dezentralen Feldelemente der ersten Energieklasse EK1 benötigten Energiemenge von 21,6 kWh bereitgestellt werden. Unter der Annahme, dass die beiden Schrankenantriebe des Bahnübergangs BÜ parallel laufen, kann aus einer derartigen Leitung keine Leistung von 12 kW entnommen werden. Aus diesem Grund kommt daher den beiden bereits eingezeichneten Energiespeichern ES1 und ES2 eine besondere Bedeutung zu. Diese sind nun so zu dimensionieren, dass der Energiespeicher ES1 im Wesentlichen zur Speisung des Bahnübergangs BÜ diesem auch Energiebus-seitig zugeordnet ist. Er ist daher so zu dimensionieren, dass er täglich eine Energiemenge von etwa 32 kWh (wegen der Reserve) übernehmen kann, was etwa der Energiemenge von vierzig Autobatterien (80 Ah, 12 VDC) für PKW entspricht. Der Energiespeicher ES2 ist im Wesentlichen zur Speisung der Weichen W1 bis W4, insbesondere auch ihrer Weichenheizungen, denselben Energiebus-seitig zugeordnet. Hier würde eine Energiemenge von etwa 3,2 kWh als ausreichend erachtet, was in der vorstehenden Metrik der Autobatterien vier Batterien entsprechen würde.This amount of energy can not be provided with the already mentioned above line 8 (220VAC, 10A) in addition to the required for the decentralized field elements of the first energy class EK1 amount of energy of 21.6 kWh. Under the assumption that the two barrier drives of the level crossing BÜ run parallel, can from such a No power of 12 kW can be taken from the line. For this reason, therefore, the two energy storage devices ES1 and ES2 already drawn are of particular importance. These are now to be dimensioned so that the energy storage ES1 is assigned to this energy bus side substantially for feeding the level crossing BÜ this. It should therefore be dimensioned so that it can take over an energy amount of about 32 kWh per day (due to the reserve), which corresponds approximately to the amount of energy of forty car batteries (80 Ah, 12 VDC) for cars. The energy storage ES2 is essentially assigned to the supply of the switches W1 to W4, in particular also their point heaters, the same power bus side. Here, an amount of energy of about 3.2 kWh would be considered sufficient, which in the above metric of the car batteries would correspond to four batteries.
Aus diesem Grunde kann hier entschieden werden, dass die zum Aufladen des Energiespeichers ES2 erforderliche Energie insgesamt auch noch mit einer grosszügigen Reserve aus der bereits an dem Energiebus EB anliegenden Leitung 8 (220VAC, 10A) entnommen werden kann. Der Energiespeicher ES2 ist lediglich so zu dimensionieren, dass er quasi eine Art Kurzschlussleistung von 6kW für die Dauer einer Minute hinsichtlich des hierfür erforderlichen Stromflusses bereitstellen kann. An dieser Stelle ist daher der gekoppelte Einsatz von geeigneten Supercaps gepaart mit Batterien angezeigt.For this reason, it can be decided here that the energy required to charge the energy store ES2 can also be taken in total with a generous reserve from the line 8 (220VAC, 10A) already applied to the power bus EB. The energy storage ES2 is merely to be dimensioned so that it can provide a kind of short-circuit power of 6kW for a period of one minute in terms of the required current flow. At this point, therefore, the coupled use of suitable supercaps paired with batteries is indicated.
Für den Energiespeicher ES1 ist daher zu prüfen, woher die benötigte Energiemenge von 32 kWh täglich stammen kann. Eine Option kann die Verstärkung der bestehenden Leitung sein. Unter der Annahme, dass diese Leitung aus einem entfernten Stellwerk herangeführt worden ist, kann eine weitere Option darin bestehen, eine zweite Leitung, insbesondere aus einem anderen öffentlichen Versorgungsnetz, heranzuführen. Diese Variante kann gegenüber der ersten Variante erheblich preiswerter sein, weil beispielsweise nur eine kurze Verlängerung einer Leitung des öffentlichen Versorgungsnetzes zu legen wäre. Eine dritte Variante könnte beispielsweise auch eine Speisung aus Photovoltaikelementen, Windturbinen oder Brennstoffzellen vorsehen. Auch eine Leistungsentnahme aus dem Fahrdraht kann eine valuable Option sein.For the energy storage ES1 it is therefore necessary to examine where the required amount of energy of 32 kWh per day can come from. One option may be the reinforcement of the existing line. Assuming that this line has been brought from a remote interlocking can be another option consist in introducing a second line, in particular from another public supply network. This variant can be considerably cheaper compared to the first variant, because, for example, only a short extension of a line of the public supply network would be to lay. A third variant could, for example, also provide a feed of photovoltaic elements, wind turbines or fuel cells. Also, a power withdrawal from the contact wire can be a valuable option.
Unter der Annahme, dass sich in der Nähe des Energiespeichers ES1 weder Versorgungslinien des öffentlichen Netzes noch Photovoltaik- und Windturbinenanlagen befinden, wird vorliegend die Entnahme der Leistung aus dem hier nicht weiter dargestellten Fahrdraht gewählt. Dank des Energiespeichers ES1 könnte der Streckenabschnitt 2 sogar eine gewisse Zeit lang mit Diesel- oder Dampffahrzeugen befahren werden, falls es zu einem Ausfall der Spannungsversorgung aus dem Fahrdraht kommen sollte.Assuming that there are neither supply lines of the public grid nor photovoltaic and wind turbine installations in the vicinity of the energy store ES1, in the present case the removal of the power from the contact wire not shown here is selected. Thanks to the energy storage ES1, the
Wie vorstehend bereits erläutert, umfasst die bereitgestellte Leistung eine Reserveleistung, die hier mindestens rund 40 Prozent des Leistungsbedarfs des räumlich und/oder zeitlich aufgelösten Verbrauchsprofils beträgt. Zur Erleichterung des Auffindens eines geeigneten Energiespeichers sind zudem die einsetzbaren Energiespeicher hinsichtlich der durch sie zur Verfügung stellbaren Energiemenge Leistungsklassen zugeordnet.As already explained above, the power provided comprises a reserve power, which here amounts to at least approximately 40 percent of the power requirement of the spatially and / or temporally resolved consumption profile. In order to facilitate the finding of a suitable energy storage device, the usable energy storage devices are also assigned power classes with regard to the amount of energy that can be provided by them.
Die vorliegende Erfindung führt daher im Ergebnis zu einer Skalierung der Leistungsaufnahme und liefert aufgrund der mittels des Fahrplans prognostizierbaren Streckenbelegung ein normatives Werkzeug, aus dem gezielt zeitlich und räumlich aufgelöste Profile der elektrischen Leistungsaufnahme ableitbar sind. Mit Hilfe dieser Profile sind im vorliegenden Ausführungsbeispiel die elektrische Grundlast, die Spitzenlast sowie die Kapazität und der physische Ort der Energiespeicher festgelegt worden. Auf diese Weise ergibt sich ein sehr detailliert vorausplanbares Modells/Profil der elektrischen Leistungsaufnahme, welche später entsprechend dieses Models/Profils bereitgestellt werden kann. Damit ist das Leistungsversorgungsnetzwerk effizient und anforderungsgerecht auslegbar, wodurch ein schonender Umgang mit Ressourcen, wie Kupferkabeln, Energiespeichermaterialien, erreicht wird.As a result, the present invention results in a scaling of the power consumption and delivers due to the predicted by means of the timetable route occupancy a normative tool, from which specifically temporally and spatially resolved profiles of the electrical power consumption can be derived. With the help of these profiles, the basic electric load, the peak load and the capacity and the physical location of the energy storage have been set in the present embodiment. In this way results in a very detailed predictable model / profile of electrical power consumption, which can be provided later according to this model / profile. This means that the power supply network can be designed efficiently and according to requirements, thus ensuring that resources, such as copper cables and energy storage materials, are used sparingly.
