Birkholz II wind farm is located in Saxony-Anhalt, Germany. It was completed in 2009 and is owned by .
It is near Birkholz.
See below for data.
As a rule, economic wind machines require a wind speed of 4.5 m/s (16 km/h) or greater.
An ideal place for a project like Birkholz II would have a near constant flow of non-turbulent wind year round, having a minimum likelihood of sudden potent bursts of wind. An essential aspect of turbine siting is furthermore access to local requirement or transmission capaBirkholz.
During the planning stages the Birkholz II wind farm would have been checked and confirmed through wind measurements. However, Birkholz II wind farm might have needed more than just meteorological data and measurements.
Site information around Birkholz is a major factor in the development choice Local winds are often watched for a year or more, and detailed wind maps built before wind generators are installed.
The wind blows more rapidly at higher altitudes because of the reduced influence of drag. The increase in velocity with altitude is most dramatic close to the surface and is affected by geography, surface roughness, and upwind limitations such as trees or buildings. Velocity increases with altitude and it is more obvious near land and is changed by terrain, surface and limitations.
Ordinarily, the rise of wind speeds with raising height follows a wind profile power law, which forecasts that wind speed rises proportionately to the seventh root of altitude. Increasing the height of a turbine, then, raises the expected wind speeds by 10%, and the predicted power by 34%.
In general, a length of 7D (7 × Rotor Diameter of the Wind Turbine) is scheduled between each turbine in a fully developed wind farm. But micrositing optimizes placement, specifically in hilly areas.
Birkholz II turbines are linked via medium voltage lines and communications.
At a substation, this kind of medium-voltage electric energy is improved in voltage with a transformer for connection to the high voltage transmission system. Building of a land-based wind farm requires setting up the collector system and substation, and perhaps roads to each turbine site.
