Buffalo Ridge II wind farm is located in South Dakota, USA. It was brought online in 2010 and is owned by Iberdrola.
It is near Brookings and Deuel Counties.
See below for data.
Wind farms, as a general rule call for wind speeds of 4.5 metres per second or higher.
A perfect position for a project like Buffalo Ridge II could have a near constant flow of non-turbulent wind throughout the year, having a minimum chance of sudden powerful bursts of wind. An important factor of turbine siting is also admittance to local demand or transmission capaBrookings and Deuel Counties.
During the planning stages the Buffalo Ridge II wind farm would have been checked and confirmed through wind measurements. However, Buffalo Ridge II wind farm might have needed more than simply meteorological data and measurements.
Site information around Brookings and Deuel Counties would have been a major element in the ‘development’ final decision Winds around Brookings and Deuel Counties are analysed for over a year or so plus the introduction of detailed maps. Only then are wind turbines installed.
The wind blows faster at higher altitudes because of the reduced influence of drag. The surge in velocity with altitude is most remarkable close to the surface and is affected by geography, surface roughness, and upwind hurdles such as trees or buildings. Velocity increases with altitude and is also more distinct near land and is altered by landscape, surface and hurdles.
Typically, the rise of wind speeds with raising height follows a wind profile power law, which anticipates that wind speed rises proportionately to the seventh root of altitude. Doubling the altitude of a turbine, then, raises the expected wind speeds by 10%, and the estimated power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they are spaced out so they don’t affect one another. But micrositing optimizes placement, particularly in hilly areas.
Individual turbines at Buffalo Ridge II are interlocked with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this particular medium-voltage electric current is improved in voltage with a transformer for connection to the high voltage transmission system. Development of a land-based wind farm requires installation of the collector system and substation, and perhaps roads to every turbine site.
