Dratum wind farm is situated in Lower Saxony, Germany. It was finished in 2001 and is owned by .
It is near Dratum.
See below for data.
Wind farms, as a general rule call for wind speeds of 4.5 metres per second or more.
A great destination for a project like Dratum could have a near constant flow of non-turbulent wind all year long, with a minimum chance of abrupt potent bursts of wind. An important factor of turbine siting is moreover admittance to local requirement or transmission capaDratum.
During the planning stages the Dratum wind farm would have been checked and authenticated through wind measurements. However, Dratum wind farm would have needed more than merely meteorological data and measurements.
Site info around Dratum would have been a major factor in the ‘development’ choice Local winds are often watched for a year or more, and detailed wind maps constructed before wind generators are set up.
Altitude would also possess a part to performwithin a project like Dratum. This is due to drag The rise in velocity with altitude is most dramatic at the surface and is impacted by geography, surface roughness, and upwind limitations such as trees or buildings. Velocity rises with altitude and it is more pronounced near land and is changed by landscape, surface and obstacles.
Wind speeds escalating with altitude is part of a wind energy law. This forecasts wind speed rises with the 7th root of altitude. Increasing the altitude of a turbine, then, enhances 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 in order that they don’t affect each other. However this might not be the case in hilly areas.
Individual turbines at Dratum are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, it medium-voltage electric energy is enhanced in voltage using a transformer for connection to 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 and every turbine site.
