Bignan wind farm is located in Bretagne, France. It was created in 2009 and is owned by .
It is near .
See below for data.
Wind farms, as a general rule call for wind speeds of 4.5 metres per second or higher.
The best destination for a project like Bignan 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 involved if Bignan was not built near local demand or transmission capa.
During the planning stages the Bignan wind farm would have been checked and endorsed through wind measurements. Meteorological wind data alone is usually not enough for exact siting of a large wind power project.
Assortment of site-specific data for wind speed and direction would have been vital to determining site potential in order to fund the project. Winds around are evaluated for at least a year or so plus the introduction of detailed maps. Only then are wind turbines installed.
The wind hits sooner at higher altitudes due to the reduced effect of drag. The boost in velocity with altitude is most spectacular close to the surface and is affected by geography, surface roughness, and upwind obstacles such as trees or buildings. Velocity rises with altitude and is more obvious near land and is altered by topography, surface and obstacles.
Usually, the rise 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, enhances the predicted wind speeds by 10%, and the estimated power by 34%.
In general, a length of 7D (7 × Rotor Diameter of the Wind Turbine) is about between each turbine in a fully developed wind farm. However this is not always the situation in hilly areas.
Bignan turbines are linked via medium voltage lines and communications.
At a substation, that medium-voltage electric current is elevated in voltage using a transformer for connection to the high voltage transmission system. Development of a land-based wind farm requires installing of the collector system and substation, and possibly roads to every turbine site.
