Definitions

  • 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 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 Switzerlandbeeinlende 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.
  • train and track section monitoring units can also be called balises and line conductors, but also axle counters and track circuits.
  • intelligent energy stores IES1 to IES4 are now connected to the energy transport network and the data transport network, so that these intelligent energy storage devices can communicate with the central signal box via the data transport network and thus a power consumption and / or delivery of one in the logic of the central interlocking implemented energy manager can be controlled.
  • the intelligent energy storage units have a local logic module, a regulation of an energy flow and a communication module.
  • WO2008 / 025414A2 describes a system for supplying field elements in a tunnel in which there is a data bus for driving and a power bus for supplying the field elements.
  • 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.
  • 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.
  • 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.
  • the present invention 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.
  • 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.
  • the usable energy stores may be assigned power classes with regard to the amount of energy that can be provided by them.
  • a concordance list can be provided which compares the consumption classes corresponding energy storage suitable performance class.
  • FIG. 1 shows a schematic view of a section 2 of a railway double lane line.
  • This section of the route additionally has a junction and junction (hereinafter referred to as intersection 4) and a road 6 intersecting the double-track section at a railway crossing BÜ.
  • intersection 4 A total of six axle counters AZ1 to AZ6 are provided for checking the entry and the complete exit of a train from the section.
  • the adjacent driving terms are visually displayed on six signals S1 to S6 and also transmitted without contact by means of six mounted in the track area Beautys B1 to B6.
  • To operate the intersection 4 four switches W1 to W4 are provided.
  • a first deviating road F1 provides for the entrance of the train at axle counter AZ1 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 carriageway F3 deviating from the basic carriageway provides access to the train at axle counter AZ2 and the exit at axle counter AZ5.
  • a fourth carriageway deviating from the basic carriageway F4 provides for the entrance of the train at axle counter AZ1 and the exit at axle counter AZ6.
  • the four aforementioned roads F1 to F4 can of course also be traveled in the opposite direction.
  • the power bus EB 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.
  • 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 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 represents the signals S1 to S6
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the removal of the power from the contact wire not shown here is selected. Thanks to the energy storage ES1, the section 2 could even be used for a certain period of time on diesel or steam vehicles if the power supply fails due to the contact wire.
  • 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.
  • the usable energy storage devices are also assigned power classes with regard to the amount of energy that can be provided by them.
  • 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.
  • a normative tool from which specifically temporally and spatially resolved profiles of the electrical power consumption can be derived.
  • 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.
  • 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.
