Butte Saint-Liphard wind project was installed in Île-de-France, France It was brought online in 2007 and is owned by Kallista Energy.
It is near Janville, Oinville-St-Liphard.
See below for data.
Wind farms, as a general rule require wind speeds of 4.5 metres per second or higher.
A great location for a project like Butte Saint-Liphard would have a near constant flow of non-turbulent wind all year round, with a minimum likelihood of abrupt potent bursts of wind. An important factor of turbine siting is furthermore admission to local demand or transmission capaJanville, Oinville-St-Liphard.
Before development, Butte Saint-Liphard was probably screened on the foundation of a wind atlas, and validated with wind specifications. However, Butte Saint-Liphard wind farm might have needed more than merely meteorological data and measurements.
Site information around Janville, Oinville-St-Liphard would have been a major element in the ‘development’ conclusion Winds around Janville, Oinville-St-Liphard are analysed 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 greater altitudes due to the reduced effect of drag. The surge in velocity with altitude is most dramatic near 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 pronounced near land and is transformed by terrain, surface and hurdles.
Ordinarily, the increase of wind speeds with growing height 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, boosts the predicted wind speeds by 10%, and the predicted 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 might not be the case in hilly areas.
Butte Saint-Liphard turbines are linked via medium voltage lines and communications.
At a substation, this particular medium-voltage electric energy 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 possibly access roads to each turbine site.
