The Fankel run-of-river power plant (also known as the Fankel Moselle power plant ) is the fourth in a chain of twelve run-of-river power plants in the German section of the Moselle . It is part of the Fankel barrage , which is located at 59.38 kilometers of water in the area of Bruttig-Fankel on the Middle Moselle. The power plant is located on the left bank of the Moselle. It is operated by RWE Innogy as a base load power plant and is able to cover the electricity needs of around 20,000 households. The central control room, from which all Moselle power plants are monitored, is also located in the immediate vicinity of the power plant.
The construction of the plant in Fankel is exemplary for all German Moselle power plants.
history
In a treaty on October 27, 1956, Germany , France and Luxembourg agreed to develop the Moselle into a major shipping route. During the extensive construction work between 1958 and 1964, the Moselle power station in Fankel was also built. Siemens-Schuckertwerke , based in Erlangen, was responsible for the design and construction management, while the construction work was carried out by Siemens- Bauunion from Munich , which is experienced in the construction of hydropower plants . In 2001 the power plant was completely overhauled.
technology
The special feature of the Moselle power station in Fankel is the flat construction of the machine hall, which, together with the barrage, fits harmoniously into the landscape .
In order to achieve this goal, the previous design with horizontally positioned Kaplan turbines , as implemented in the Moselle power station in Koblenz , was out of the question. Instead, the nacelle was designed for the installation of bulb turbines . This also made it possible to reduce the width of the intake structure by around 30 percent.
The four machine sets of the Moselle power station in Fankel consist of a bulb turbine with a planetary gear connected downstream and a three-phase synchronous generator . Each machine set is located in a streamlined steel housing that is washed by the water and rests on a concrete foundation at an angle of 8 ° to the horizontal. The gearbox and generator are accessible from the machine hall. A gantry crane is installed in the hall for assembly and maintenance work . The electricity generated is fed into the power grid via machine transformers . The operation of the power plant is fully automatic and is monitored by the nearby central control room at the Fankel barrage.
turbine
The power plant's double-regulated bulb turbines are designed for a water throughput of 100 m³ / s. They are controlled by the hydraulically adjustable blades of the rotating impeller or the fixed guide apparatus and by air vessels. The four-blade impeller has a diameter of 4.72 meters and runs at a speed of 77 rpm. The diffuser has 20 blades.
Gearbox and generator
The input speed of the turbine is increased to the generator speed of 750 / min via a planetary gear from Bayerische Hüttenwerke Sonthofen . As a result, a comparatively compact generator can be used. The 8-pole three-phase synchronous generator , which is designed as a salient pole machine, develops an electrical output of 4775 kVA at a nominal voltage of 6.3 kV . Generators and planetary gears are air-cooled; their waste heat is sufficient to heat the turbine hall.
