Dannhausen wind project was installed in Lower Saxony, Germany It was created in 2008 and is owned by .
It is near .
See below for data.
Wind farms, as a general rule need wind speeds of 4.5 metres per second or more.
An ideal location for a project like Dannhausen would have a near constant flow of non-turbulent wind all year round, having a minimum likelihood of sudden powerful bursts of wind. An essential aspect of turbine siting is also access to local demand or transmission capa.
During the planning stages the Dannhausen wind farm would’ve been checked and endorsed through wind measurements. However, Dannhausen wind farm would have needed more than simply meteorological data and measurements.
Site info around would have been a major element in the ‘development’ final decision Local winds are often supervised for a year or more, and comprehensive wind maps built before wind generators are installed.
Altitude would also possess a part to performwithin a project like Dannhausen. This is because of drag The rise in velocity with altitude is most remarkable near the surface and is affected by topography, surface roughness, and upwind hurdles such as trees or buildings. Velocity increases with altitude and it is more obvious near land and is changed by geography, surface and obstacles.
Wind speeds increasing with altitude is part of a wind energy law. This predicts wind speed rises with the 7th root of altitude. Doubling the elevation of a turbine, then, raises the predicted wind speeds by 10%, and the anticipated power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they are spaced out to make sure they don’t affect each other. But micrositing increases placement, specially in hilly areas.
Individual turbines at Dannhausen are interconnected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, it medium-voltage electric energy is improved in voltage using a transformer for link with the high voltage transmission system. Building of a land-based wind farm requires installation of the collector system and substation, and possibly roads to each turbine site.
