The power plant Wienerbruck is in Annaberg in the southern Lower Austria located storage power plant of EVN . The historic building has been open to the public since 2015 with an exhibition in the gallery in the machine hall. The power plant is fed by the water of the Lassingbach and the Erlauf . The power plant is still in operation. The bottleneck capacity is 7.8 MW . The power station mainly generates 50 Hz three-phase current for the public network, two old machine sets were available as a reserve for generating traction current with the frequency of 25 Hz that is unique to the Mariazell Railway . (The Mariazellerbahn has been supplied from the Klangen converter plant since 2014.) An original machine is still operational. The electricity it generates is now converted to 50 Hz in the Erlaufboden power plant and fed into the national grid.
history
As a basis for the construction of the power plant, a contract for the supply of the Mariazellerbahn was signed in 1908. The power plant's planner and site manager was Eduard Engelmann junior , on whose initiative the entire electrification of the Mariazell Railway was tackled. Originally, the power plant was equipped with four 25 Hz three-phase generators with a total output of 6.6 MW. When it opened in 1911, it was the largest storage power plant in Austria-Hungary . In the region, the public supply was originally provided with 25 Hz three-phase current, for the single-phase supply of the Mariazellerbahn a maximum of 4.5 MW could be generated. In 1924, the Erlaufboden power plant was put into operation to provide support . The Wienerbruck power plant was partially renewed in 1972/76. In 2008, as in the neighboring Erlaufboden power station, the electrotechnical equipment as well as the control rooms and controls were revitalized and renewed.
Machine sets
The Wienerbruck power plant has four sets of machines:
- Machine set 1 was built in 1974 and is powered by water from the Wienerbruck reservoir via a Pelton turbine . The output of the 50 Hz generator is 2.1 MW.
- Machine set 2 dates from 1908/10 and is also driven by water from the Wienerbruck reservoir via a Pelton turbine, the 25 Hz generator has an output of 1 MW.
- Machine set 3 was powered by water from the Erlaufstausee and is similar to machine set 2 (shut down).
- The machine set 4 from 1972 is driven with water from the Erlaufstausee via a Francis turbine . The rated output of the 50 Hz generator is 4.8 MW.
The electricity generated is fed via a 30 kV line to the outdoor switchgear in the Erlaufboden power plant.
