Croix des 3 Chesnots wind farm is situated in Bretagne, France. It was brought online in 2010 and is owned by .
It is near .
See below for data.
As a general rule, economic wind power generators require a wind speed of 4.5 m/s (16 km/h) or more.
The very best destination for something like Croix des 3 Chesnots would be a steady supply of non-turbulent wind. An essential aspect of turbine siting is also admittance to local requirement or transmission capa.
Before development, Croix des 3 Chesnots was probably screened on the foundation of a wind atlas, and validated with wind specifications. However, Croix des 3 Chesnots wind farm might have needed more than merely meteorological data and measurements.
Site information around is a major aspect in the development conclusion Winds around are analysed for at least a year or so plus the introduction of detailed maps. Only then are wind turbines installed.
The wind hits faster at greater altitudes as a result of reduced influence of drag. The rise in velocity with altitude is most spectacular close to the surface and is impacted by geography, surface roughness, and upwind obstructions such as trees or buildings. Velocity boosts with altitude and is also more distinct near land and is altered by topography, surface and limitations.
Wind speeds growing with altitude is part of a wind energy law. This Bretagnes wind speed rises with the 7th root of altitude. Increasing the elevation of a turbine, then, raises 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 so that they don’t affect one another. But micrositing optimizes placement, specially in hilly areas.
Individual turbines at Croix des 3 Chesnots are interconnected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this kind of medium-voltage electric current is increased in voltage with a transformer for link with the high voltage transmission system. Development of a land-based wind farm requires setting up the collector system and substation, and probably access roads to each turbine site.
