Dransfeld wind farm is located in Lower Saxony, Germany. It was completed in 2001 and is owned by .
It is near Dransfeld.
See below for data.
In most cases, economic wind power generators require a wind speed of 4.5 m/s (16 km/h) or higher.
The best location for something such as Dransfeld is a steady supply of non-turbulent wind. An essential aspect of turbine siting is also admittance to local requirement or transmission capaDransfeld.
Before development, Dransfeld was probably screened on the foundation of a wind atlas, and validated with wind measurements. However, Dransfeld wind farm would have needed more than simply meteorological data and measurements.
Collection of site-specific data for wind speed and direction would have been vital to determining site potential as a way to finance the project. Local winds are frequently supervised for a year or more, and comprehensive wind maps built before wind generators are set up.
Altitude would also have a part to performin a project like Dransfeld. This is due to drag The rise in velocity with altitude is most spectacular at the surface and is impacted by geography, surface roughness, and upwind hurdles such as trees or buildings. Velocity grows with altitude and is more pronounced near land and is altered by terrain, surface and hurdles.
Generally, the rise of wind speeds with growing height follows a wind profile power law, which predicts that wind speed rises proportionately to the seventh root of altitude. Doubling the elevation of a turbine, then, raises the anticipated wind speeds by 10%, and the estimated power by 34%.
In general, a distance 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 situation in hilly areas.
Dransfeld turbines are linked via medium voltage lines and communications.
At a substation, this particular medium-voltage electric current is increased in voltage with a transformer for connection to the high voltage transmission system. Construction of a land-based wind farm requires installation of the collector system and substation, and probably access roads to each turbine site.
