Cabreirens wind farm is located in Midi-Pyrénées, France. It was finished in 2009 and is owned by .
It is near .
See below for data.
Wind farms, as a general rule demand wind speeds of 4.5 metres per second or more.
An ideal location for a project like Cabreirens could have a near constant flow of non-turbulent wind all year round, having a minimum likelihood of abrupt effective bursts of wind. Additionally, you wouldn’t get a turbine like associated if Cabreirens was not built near local demand or transmission capa.
Before development, Cabreirens was almost certainly screened on the basis of a wind atlas, and validated with wind specifications. Meteorological wind data alone is usually not adequate for exact siting of a large wind power project.
Site information around would have been a major aspect in the ‘development’ decision Winds around are evaluated for over a year or so alongside the development of detailed maps. Only then are wind turbines installed.
The wind hits sooner at greater altitudes as a result of reduced influence of drag. The rise in velocity with altitude is most spectacular at the surface and is impacted by landscape, surface roughness, and upwind obstacles such as trees or buildings. Velocity grows with altitude and is more distinct near land and is transformed by terrain, surface and obstructions.
Wind speeds raising with altitude is part of a wind energy law. This Midi-Pyrénéess wind speed rises with the 7th root of altitude. Increasing the altitude of a turbine, then, boosts the anticipated wind speeds by 10%, and the estimated power by 34%.
In general, a length of 7D (7 × Rotor Diameter of the Wind Turbine) is set between each turbine in a fully developed wind farm. But this might not be the way it is in hilly areas.
Individual turbines at Cabreirens are interconnected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this medium-voltage electric current is improved in voltage with a transformer for link with the high voltage transmission system. Development of a land-based wind farm requires installing of the collector system and substation, and perhaps access roads to every turbine site.
