The Koblenz run-of-river power plant (also Moselle power plant Koblenz ) is the first in a chain of twelve run-of-river power plants in the German section of the Moselle . It forms a unit with the Koblenz barrage and is located at 1.94 kilometers on the right bank of the Moselle in the immediate vicinity of the mouth of the Moselle ( Deutsches Eck ) in Koblenz . The power plant is operated by RWE Innogy and with an installed capacity of 16 MW, as a base load power plant , is able to cover the electricity needs of around 18,000 households.
history
The realization of the Moselle power station Koblenz goes on plans of the national government from the years 1938 to 1940 back to the expansion of the Mosel to the shipping lane with six barrages FROM ROCHE.
Construction of the Koblenz barrage by the Bauwens company from Cologne began in 1941, but had to be stopped during the Second World War . Construction work was not resumed until 1948 under the supervision of the French occupying forces . The power plant was commissioned in 1951.
technology
Four machine sets are installed in the Moselle power station in Koblenz . One set consists of a Kaplan turbine with a vertical shaft and a three-phase synchronous generator arranged above it , designed as a so-called screen generator . The electricity generated is fed into the power grid via two machine transformers . They are set up outdoors on the right bank of the Moselle in the area of the intake structure . The machine house has a length of 40.10 m from the inlet rake to the mouth of the turbine suction pipe. The inlet area of the turbines is 68.80 m wide. The gantry crane on the roof of the machine house enables assembly and maintenance work on the machine sets. The operation of the power plant is fully automatic and is monitored by the central control room at the Fankel barrage.
turbine
The turbines used in the Moselle power plant in Koblenz are double-regulated Kaplan turbines, which are designed for a volume flow of 95 m³ / s. They are controlled by the hydraulically adjustable blades of the rotating impeller or the fixed guide apparatus and by air vessels. The impeller is equipped with five blades and has a diameter of 4.9 meters. The nominal speed is 71.5 / min. The diffuser has 24 blades.
generator
The 84-pole salient pole machine is directly coupled to the turbine and delivers an electrical output of 4 MVA at a nominal voltage of 10.5 kV .
