Description

Method and system for providing the electrical power to decentralized field elements of a

Railway network

The present invention relates to a method and system for providing electrical power to distributed field elements of a railway network.

Such decentralized field elements are in

Rail transport networks used to control the rail vehicles affecting and / or the rolling stock monitoring units and to monitor the functionality and to record and report back process data. As train-influencing units, that is

Give instructions to the driver or even make direct intervention in the vehicle control or directly set a safe track, for example, signals, switches, 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, are considered. As a train and track section monitoring units can also balises and line conductors, but also axle and

Track circuits are called.

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 are usually provided today standardized copper cables, for their classic

Travel distances because of the physical

Transmission parameter, 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.

According to European Patent Application EP 2 301 202 A1, a device and a method for controlling and / or monitoring decentralized devices arranged along a traffic network are available to remedy this limitation

Field elements are known, which comprise the following key points: a) a higher-level control system, with the

decentralized field elements by means of data telegrams

Exchanging information,

b) a data transport network with a number of

Network access points, wherein the higher-level control system via at least one network access point to the

Data transport network is coupled;

c) communication units, each at a

Network access point are connected, 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, each via a communication unit and via a network access point on the data transport network

is coupled. In this way, for the decoupling of the decentralized

Field elements a digital transport network can be used, which in any way robust against a simple

Error event is, nevertheless, a very skillful 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 will

for example under the name SiNet® from Siemens

Switzerland AG distributed. As part of the further education of this project, the electrical power supply of decentralized

Field elements increasingly no longer made from the interlocking, but with the help of the use of a

Signal box completely independent power supply network to be solved.

Here, according to the European patent application 11 189 530.6 in the power supply network and decentralized

Memory elements have been proposed which are to be used in particular for smoothing load peaks in the network. This solution proposed in the European patent application 11 189 530.6 includes the functionality of SiNet® according to the European patent application EP 2 301 202 A1 with regard to the data technology situation with a new energy supply concept. All element controllers of the decentralized field elements are now connected to a common energy transport network. The

Infeed of electrical energy is now no longer exclusively from the central interlocking, but also takes place via external power supplies, but otherwise no longer have any relation to the data processing of the element controller. At suitable positions of the energy transport network are now intelligent energy storage IES1 to IES4 on the energy transport network and the

Data transport network connected, so this

intelligent energy storage data technology over the

Datenentransportnet z can communicate with the central signal box and thus a power consumption and / or -abgäbe can be controlled by an implemented in the logic of the central signal box energy manager. In addition to a charging device with inverter and the actual energy store, the intelligent energy storage units have a local logic module, a regulation of an energy flow and a communication module.

According to this new concept, an interlocking computer for the same decentralized field elements then only needs four cable cores for the electrical energy and up to four

Cable wires for communication out. It is the

Interlocking computer also connected via a network access point to the data transport network.

In this way, there is a respect to the

used decentralized field elements and the intelligent energy storage a scalable situation in the track area. It is also possible to use scalable cable models and

Scalable energy storage can be used. When

Energy storage can also mechanical

Flywheel storage and super capacitors are used. Therefore, this solution also shows the usefulness of this concept of decentrally distributed energy storage in the

Energy transport network, so that the interpretation of the

Energy transport network can use the contribution of energy storage to the effect that the wires of the

Network only for a predeterminable basic service

must be interpreted.

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

Periodically recharge memory elements 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 bases

exist . The above-mentioned problem has not yet been solved because the concept of the decoupled from the signal box power supply network has not yet been implemented in the railway sector and a veritable

Paradigm shift represents because many decentralized

Field elements can no longer be monitored by the direct monitoring of the electrical power consumption from the interlocking ago.

The present invention is therefore based on the object, a system and a method for providing the

specify electrical power to decentralized field elements of a railway network, covered by means of a basic supply a base load and

Memory elements can be charged so that they can provide the required peak load if necessary.

With regard to the method, this object is achieved according to the invention by a method for providing the electrical power to decentralized field elements of a

Railway network, in which the following steps are carried out:

a) allocate the power consumption of the decentralized

Field elements to predetermined consumption classes;

b) adding up in a section of the

Railway network arranged decentralized field elements in terms of their consumption classes associated

Power consumption for setting a first

Fahrplangemässen road, starting from a set basic route, c) repeating step b) for a number of

Fahrplangemäs sen roads for a predetermined

Time interval, wherein for the n-th road the previously set (n-l) -th road is used as a basic road;

d) determining a spatially and / or temporally resolved consumption profile for the considered time interval; e) according to the spatially and / or temporally resolved consumption profile, the assignment of a basic service in a the route section assigned

Energy supply network and the assignment of

rechargeable storage elements to this stretch, the basic performance and the performance of

Memory elements are designed, at least one

To provide power requirements of spatially and / or temporally resolved consumption profile in the required temporal and / or spatial granularity.

Regarding the system, this object is achieved by a system for providing the electrical

Power at decentralized field elements of a

Railway network solved the following

Components includes:

a) means for allocating the power consumption of the decentralized field elements to predetermined consumption classes;

b) means for summing the decentralized field elements arranged in a section of the railway network with regard to their consumption classes assigned

Power consumption for setting a first

Fahrplangemässen road, starting from a set basic route,

c) means for repeating step b) for a number of Fahrplangemäs sen roads for a predetermined time interval, wherein for the n-th road the previously set (nl) -th road is used as the basic road;

d) means for determining one for the considered one

Time interval spatially and / or temporally resolved

Consumption profile;

e) an associated with the route section

Energy supply network, according to the spatially and / or temporally resolved consumption profile the

Assignment of a basic service and the allocation of rechargeable storage elements is made so that the

Basic performance and the performance of the memory elements are designed together to provide at least the power requirement of the spatially and / or temporally resolved consumption profile in the required temporal and / or spatial granularity.

In this way, a predictive scaled forecast of the power consumption of electrical results

Field elements based on the timetable

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) with which

Performance classes are arranged in the rail network. In this case, the exact position of the field elements is determined and assigned to specific routes.

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 are activated when changing from an nth road to the (n + l) -th road must and which field elements within the

Track section (block section) must be operated periodically or permanently regardless of the selected route. In the context of this proecting, the individual decentralized field elements are standardized

Energy / Leistungsaufhähme (class) assigned, so for a section of the route to be provided

Energy / power can be determined relatively accurately in terms of time and space within the scope of this project.

By means of this configuration data, the electric supply network will then be determined with regard to the base load and the

projected memory elements and the distinct location of these memory elements projected 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. 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 profiles of the electrical and temporal resolution of the electrical system are obtained

Power consumption are derivable. With the help of these profiles, the basic electric load, the peak load as well as the capacity and the physical location of the energy storage

established. In this way results in a very detailed predictable models / profile of the electrical

Power consumption, which later according to this

Model / Profile can be provided. This makes the power supply network efficient and

according to the requirements, resulting in careful handling with resources such as copper cables, energy storage materials can be achieved.

In an advantageous embodiment of the present invention

Invention may be provided, at least two

To define consumption classes, with the first

Consumption class decentralized field elements with low and rather permanent power demand represents and the second consumption class decentralized field elements with

represents a comparatively high, but short-lasting power requirement. 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 only short lasting

Power requirements are, for example, the point machines and barrier drives and their respective

Control devices.

In particular, by delays or by

Special events, such as large fairs, concerts or sporting events, may be a temporary deviation of the determined spatially and / or temporally resolved

Consumption profiles occur. For this extra demand

Where appropriate, to be able to absorb the funds available, provision may be made for the provision of the service to include a reserve capacity of approximately 20 to 60 per cent of the power requirement of the spatially and / or temporally split consumption profile. Thus, the case of temporary deviations from the consumption profile will usually have to be mastered. However, should the amount of energy available be exceeded by the actual demand, for example, the reserve power of an adjacent Track section or another source of energy, such as a public network line or the contact wire, tapped temporarily. To facilitate the pro ecting, it can be provided that the usable energy storage devices can 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 may be provided which corresponds to the consumption classes

Energy storage of suitable power class faces. In this way, a pro ektierbarkeit quasi results according to the system of a modular system, which is so also preferably programmable, creating a pro ectiertes layout

For example, with an appropriate software would be automatically created. Any adjustments could then be configured by hand in this layout.

Further advantageous embodiments of the present invention

Invention can be found in the remaining subclaims.

Preferred embodiments of the present invention are explained below with reference to a drawing. Showing:

Figure 1 is a schematic view of a section of track with a double track section with branch point; and

Figure 2 is a tabular view of this

Route section arranged decentralized

Field elements with their associated positioning and securing devices. FIG. 1 shows a schematic view of a section 2 of a railway double lane line. This section also has a branch and

Junction parts (hereinafter referred to as Junction 4) on and a double track at a level crossing BÜ intersecting road 6 on. To control the input and output

complete exit of a train from the section a total of six axle counter AZl to AZ6 are provided. The adjacent driving terms are visually displayed on six signals Sl to S6 and also by means of six in the

Track area mounted balises Bl to B6 transmitted without contact. To operate the intersection 4 four switches Wl to W4 are provided. In the basic position for this section 2 there are two non-deflected basic routes, i. Entry of the train at axle counter AZl and exit at axle counter AZ3 and vice versa and entrance of the train at axle counter AZ4 and exit at axle counter AZ2 and vice versa. A first deviating road Fl provides for the entrance of the train at axle counter AZl and the exit at axle counter AZ5. A second route F2 deviating from the basic route provides access to the train at axle counter AZ6 and the exit at axle counter AZ2. A third of the

Basic route deviating route F3 sees the

Entry of the train at axle counter AZ2 and exit at axle counter AZ5. A fourth route F4 deviating from the basic route provides access to the train at the axle counter AZl and the exit at the axle counter AZ6. The four above-mentioned routes Fl to F4 can of course be traveled in the opposite direction. 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.

For pro ecting the power bus EB, it is particularly advantageous to know which electrical powers are to be provided at which time by the power bus EB. Especially in remote areas can be determined in this way, whether certain locally existing

Voltage supply sources can be tapped or whether additional, but usually expensive measures to

Provision of more electrical power is required.

That's why it's first in this

Embodiment provided for the decentralized

Field elements two consumption classes EK1 and EK2 too

define, with the first consumption class EK1 decentralized field elements with low and rather permanent

Power requirements, such as the axle counters AZ1 to AZ6, the balises B1 to B6 and the signals S1 to S6 and the second consumption class EK2 decentralized field elements with relatively high, but short-lasting

Power requirements, such as the level crossing BÜ and the

Weichen Wl to W4, represented. The energy class EK1 can therefore have a mean permanent power consumption of 50 watts, i. 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, assigned. Assuming that the axle counters AZ1 to AZ6, the balises B1 to B6 and the signals S1 to S6 are permanently switched on, this results in this case

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.

Assuming the following line assignment, the power consumption of the decentralized field elements with the energy class EK2 can then also be estimated:

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 Fl 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 opened 10 times in 19 hours per hour, which corresponds to an energy quantity 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.

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 already recorded energy storage ESI and ES2 is of particular importance. These are now to be dimensioned so that the

Energy storage ESI essentially to power the

Level crossing BÜ this energy bus side is assigned. 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 the same for feeding the switches Wl to W4, in particular also their point heaters

Energy bus side assigned. 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.

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 is therefore the

coupled use of suitable supercaps paired with batteries displayed. For the energy storage ESI 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 significantly cheaper compared to the first variant, because, for example, only a short

Extension of a public administration

Supply network would be. 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.

Assuming that is close to the

Energy storage ESI neither supply lines of the

public grid still photovoltaic and

Wind turbine plants are present is the removal of the power from the not shown here

Contact wire selected. Thanks to the energy storage ESI, section 2 could even be used on diesel or steam vehicles for a certain period of time if there is a loss of power from the contact wire.

As already explained above, the

provided capacity is at least about 40 percent of the power requirement of the spatially and / or temporally resolved consumption profile. To facilitate the finding of a suitable

Energy storage are also the usable energy storage in terms of them available

Energy quantity assigned to performance classes.

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 are derivable. 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 in line with requirements, which enables the careful use of resources such as copper cables,

Energy storage materials, is achieved.
