Alltwalis (formerly Blaengwen) wind project was installed in Wales, UK It was in fact brought online in 2009 and is owned by Statkraft.
It is near North-east of Alltwalis, 12km north of Carmarthen.
See below for data.
Wind farms, as a general rule require wind speeds of 4.5 metres per second or higher.
The best destination for something such as Alltwalis (formerly Blaengwen) would be a steady availability of non-turbulent wind. An important factor of turbine siting is furthermore admission to local demand or transmission capaNorth-east of Alltwalis, 12km north of Carmarthen.
Before building, Alltwalis (formerly Blaengwen) was probably screened on the foundation of a wind atlas, and validated with wind measurements. Meteorological wind data alone is usually not enough for correct siting of a large wind power project.
Collection of site-specific data for wind speed and direction could have been essential to determining site potential to be able to finance the project. Winds around North-east of Alltwalis, 12km north of Carmarthen are examined for over a year or so alongside the development of detailed maps. Only then are wind turbines installed.
The wind hits quicker at greater altitudes because of the reduced influence of drag. The surge in velocity with altitude is most spectacular at the surface and is impacted by landscape, surface roughness, and upwind limitations such as trees or buildings. Velocity increases with altitude and is also more distinct near land and is altered by topography, surface and limitations.
Ordinarily, the increase of wind speeds with increasing height follows a wind profile power law, which anticipates that wind speed rises proportionately to the seventh root of altitude. Doubling the height of a turbine, then, raises the anticipated wind speeds by 10%, and the estimated power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out so they really don’t affect each other. But micrositing maximizes placement, particularly in hilly areas.
Alltwalis (formerly Blaengwen) turbines are connected via medium voltage lines and communications.
At a substation, that medium-voltage electric energy is improved in voltage using a transformer for connection to the high voltage transmission system. Building of a land-based wind farm requires setting up the collector system and substation, and possibly roads to each turbine site.
