Dobberkau II wind project was installed in Saxony-Anhalt, Germany It was brought online in 2007 and is owned by .
It is near Dobberkau.
See below for data.
Wind farms, as a general rule require wind speeds of 4.5 metres per second or more.
A great destination for a project like Dobberkau II would have a near constant flow of non-turbulent wind year round, having a minimum likelihood of sudden powerful bursts of wind. Additionally, you wouldn’t get a turbine like included if Dobberkau II was not built near local demand or transmission capaDobberkau.
During the planning stages the Dobberkau II wind farm would’ve been checked and confirmed through wind measurements. However, Dobberkau II wind farm would have needed more than merely meteorological data and measurements.
Collection of site-specific data for wind speed and direction could have been vital to determining site potential in order to fund the project. Local winds are often checked for a year or more, and comprehensive wind maps made before wind generators are set up.
The wind blows more rapidly at greater altitudes due to the reduced influence of drag. The surge in velocity with altitude is most spectacular near the surface and is affected by geography, surface roughness, and upwind obstacles such as trees or buildings. Velocity grows with altitude and is also more distinct near land and is altered by landscape, surface and obstacles.
Wind speeds raising with altitude is part of a wind energy law. This predicts wind speed rises with the 7th root of altitude. Doubling the height of a turbine, then, increases the predicted wind speeds by 10%, and the expected power by 34%.
In general, a range of 7D (7 × Rotor Diameter of the Wind Turbine) is set between each turbine in a fully developed wind farm. However this is not always the case in hilly areas.
Individual turbines at Dobberkau II are interconnected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this medium-voltage electric current is enhanced in voltage with a transformer for connection to the high voltage transmission system. Building of a land-based wind farm requires installing of the collector system and substation, and perhaps roads to every turbine site.
