Railway power plant

from Wikipedia, the free encyclopedia

A railway power plant is a power plant that generates electrical energy for rail operations . In Germany , Austria , Sweden , Norway and Switzerland , the single-phase alternating voltage with a frequency of 16 2 ⁄ 3  or 16.7 Hz. While the Austrian Federal Railways almost only operate pure rail power plants, such are rather rare in other countries, such as Germany. Far more common are power plants in which both industrial power generators and traction power generators are located. In addition, there are railway-owned power plants that are not traction power plants, as they cannot generate traction current, but only electricity for the public network, i.e. 50 Hz three-phase current in DA-CH . Railway power plants are designed as hydropower plants , conventional thermal power plants and nuclear power plants . Even wind and solar farms for the sole production of traction power have already been realized.

Railway power networks for long-distance rail transport in Europe

The traction current generators for alternating current with reduced frequency, the standard u. a. of the DACH countries are considerably larger than those for the public power grid, the associated turbines are custom-made.

Germany

Power plants in Germany that are wholly or partially used to generate traction power:

Wind farms

These generate three-phase alternating current with a frequency of 50 Hz, which the railways pick up. They are therefore not rail power stations in the strict sense of the word.

Hydropower plants

Nuclear power plants

Thermal power plants

In contrast to the current advertising strategy of DB AG, this part of the traction power supply is not “green traction power” in the sense of the general understanding of the term. See also: traction current -> energy consumption and origin

There are also connections to the traction current networks of the Austrian and Swiss Federal Railways , via which electrical energy can be exchanged with the German traction current network.

Former plants

The railway's own power plant for 300 V direct current of the Frankfurt-Offenbacher Trambahn-Gesellschaft from 1884

Austria

The Austrian Federal Railways produce most of their traction current themselves. 93 percent of the energy is currently obtained from renewable energy sources (mostly hydropower plants). Six percent of the energy is purchased from wind energy and biomass. In addition, negotiations were held on possible investments in wind power plants. In 2010, wind turbine manufacturer Leitner confirmed discussions and listed Burgenland as a possible location. In Burgenland, ÖBB does not currently have any power generation facilities.

Railway power plants

All of the railway's own power plants are operated unmanned and controlled and monitored by the central control center in Innsbruck.

Spullersee
This storage power plant was built between 1919 and 1925 as the second power plant of the Austrian State Railways to supply the Arlbergbahn . The construction of such a large power plant was a technical pioneering achievement at the time and was admired all over Europe.
Braz
This run-of- river power plant is located 10 km west of the Spullersee power plant. It was built between 1947 and 1954 to meet the increased energy requirements of the Austrian State Railways. The Braz power plant is the lower stage of the Spullersee power plant. The Braz power plant is served by the Alfenz or with water processed by the Spullersee power plant.
Fulpmes
This run-of-river power plant was built between 1977 and 1983 about 20 km south of Innsbruck in the municipality of Fulpmes in the Stubai Valley . The peculiarity of this is that in the Swedish construction, i.e. H. was built as a shaft power plant. The headwater is collected below Fulpmes in the Stubai Valley. The installed capacity is 15 MW, with two Francis turbines working on a gradient of 182 m. Before the completion of the Fulpmes power plant, the ÖBB operated the " Ruetzkraftwerk " in Schönberg , which was originally built to supply electricity to the Mittenwaldbahn .
Stubachtal power plant group
Group of four high-alpine storage power plants in the Hohe Tauern ; Expansion to pump storage, ÖBB's largest power plant.
Obervellach
This run-of-river power plant was put into operation together with the power plant-Enzigerboden storage plant in 1929 for the 16.7 Hz traction power supply of the Gisela-Bahn . Since the electrification of the Tauern Railway in 1935, the two steep ramps have also been supplied with 700 meters of altitude each.
Obervellach II
Only when planned, will Obervellach II from 2024 deliver 30 percent more electricity than the old systems at Obervellach and Mallnitz do today. The power plant is currently (as of 05/2018) in the tendering phase.
Lassach
This run-of-river power plant was built in 1905 as part of the construction site for the railway Tauern tunnel . It lies between Obervellach and Mallnitz am Mallnitzbach . It does not supply traction current, but three-phase current that is fed into the network of " KELAG " (Kärntner Elektrizitäts-Aktiengesellschaft).
Rosenbach
This was built in 1902 in the course of setting up the construction site for the railway Karawanken tunnel . It does not provide traction current, but three-phase current .

Non-rail power plants

Wienerbruck
This storage power plant is operated by " EVN AG " (Energieversorgung Niederösterreich AG), which is responsible for the overhead line of the Mariazellerbahn. The storage power plant is located in Annaberg in southern Lower Austria and is fed by the water of the Lassing and Erlauf with a total output of 6.6 MW. 4.5 MW of this is provided as single-phase alternating current with a frequency of 25 Hz for the Mariazell Railway.
Weyer
This run-of-river power plant on the Upper Austrian Enns River near the Styrian border is operated by Ennskraftwerke AG in surge operation. The total output of the two machine sets is 36.8 MW. The output of the machine set for single-phase alternating current is 18 MW.
St. Pantaleon
This diversion power plant at the confluence of the Enns into the Danube is operated by Ennskraftwerke AG in surge mode. The total output of the two machine sets is 51.9 MW. The output of the machine set for single-phase alternating current is 25 MW.

Switzerland

In Switzerland, traction current is partly obtained from SBB power plants and from third-party power plants.
