Cottonwood wind project was installed in Minnesota, USA It was completed in 2005 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 higher.
The best destination for something similar to Cottonwood is a steady availability of non-turbulent wind. Additionally, you wouldn’t get a turbine like included if Cottonwood was not built near local demand or transmission capa.
Before development, Cottonwood was probably screened on the basis of a wind atlas, and validated with wind measurements. Meteorological wind data alone is usually not sufficient for accurate siting of a large wind power project.
Site information around would have been a major element in the ‘development’ decision Local winds are frequently monitored for a year or more, and comprehensive wind maps created before wind generators are set up.
Altitude would also possess a part to playwithin a project like Cottonwood. This is due to drag The increase in velocity with altitude is most dramatic at the surface and is affected by topography, surface roughness, and upwind obstacles such as trees or buildings. Velocity boosts with altitude and is more obvious near land and is changed by terrain, surface and obstructions.
Normally, the rise of wind speeds with escalating elevation follows a wind profile power law, which predicts that wind speed rises proportionately to the seventh root of altitude. Increasing the elevation of a turbine, then, raises the anticipated wind speeds by 10%, and the predicted power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out so they don’t affect one another. But micrositing optimizes placement, specifically in hilly areas.
Individual turbines at Cottonwood are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this particular medium-voltage electric energy is increased in voltage using 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 and every turbine site.
