Big Horn II wind farm is located in Washington, USA. It was finished in 2010 and is owned by Iberdrola.
It is near Klickitat.
See below for data.
Wind farms, as a general rule need wind speeds of 4.5 metres per second or more.
An ideal place for a project like Big Horn II would have a near constant flow of non-turbulent wind year round, with a minimum chance of sudden powerful bursts of wind. Additionally, you would not get a turbine Iberdrola like Iberdrola associated if Big Horn II was not built near local demand or transmission capaKlickitat.
Before development, Big Horn II was probably screened on the basis of a wind atlas, and validated with wind specifications. Meteorological wind data alone is usually not ample for precise siting of a large wind power project.
Assortment of site-specific data for wind speed and direction might have been essential to determining site potential to be able to fund the project. Winds around Klickitat are evaluated for at least a year or so plus the creation of detailed maps. Only then are wind turbines installed.
The wind blows more rapidly at higher altitudes as a result of reduced effect of drag. The rise in velocity with altitude is most extraordinary close to the surface and is affected by landscape, surface roughness, and upwind hurdles such as trees or buildings. Velocity rises with altitude and is also more evident near land and is transformed by landscape, surface and obstacles.
Typically, the growth of wind speeds with growing height follows a wind profile power law, which anticipates that wind speed rises proportionately to the seventh root of altitude. Increasing the altitude of a turbine, then, enhances the expected wind speeds by 10%, and the anticipated power by 34%.
In general, a distance of 7D (7 × Rotor Diameter of the Wind Turbine) is defined between each turbine in a fully developed wind farm. However this isn’t necessarily the case in hilly areas.
Big Horn II turbines are linked via medium voltage lines and communications.
At a substation, this kind of medium-voltage electric current is increased in voltage using a transformer for link with the high voltage transmission system. Building of a land-based wind farm requires setting up the collector system and substation, and possibly access roads to each turbine site.
