Difwind Ltd I wind project was set up in California, USA It was in fact brought online in 1986 and is owned by EDF Energies Nouvelles.
It is near San Gorgonio.
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 Difwind Ltd I could have a near constant flow of non-turbulent wind throughout the year, with a minimum probability of abrupt effective bursts of wind. Additionally, you would not get a turbine EDF Energies Nouvelles like EDF Energies Nouvelles included if Difwind Ltd I was not built near local demand or transmission capaSan Gorgonio.
During the planning stages the Difwind Ltd I wind farm would have been checked and confirmed through wind measurements. However, Difwind Ltd I wind farm would have needed more than just meteorological data and measurements.
Collection of site-specific data for wind speed and direction could have been crucial to determining site potential as a way to fund the project. Winds around San Gorgonio are analysed for at least a year or so alongside the development of detailed maps. Only then are wind turbines installed.
The wind blows speedier at higher altitudes due to the reduced influence of drag. The surge in velocity with altitude is most remarkable close to the surface and is impacted by topography, surface roughness, and upwind hurdles such as trees or buildings. Velocity rises with altitude and is more pronounced near land and is transformed by topography, surface and limitations.
Sometimes, the increase of wind speeds with increasing elevation follows a wind profile power law, which forecasts that wind speed rises proportionately to the seventh root of altitude. Doubling the elevation of a turbine, then, boosts the expected wind speeds by 10%, and the estimated power by 34%.
In general, a range of 7D (7 × Rotor Diameter of the Wind Turbine) is scheduled between each turbine in a fully developed wind farm. However this might not be the way it is in hilly areas.
Individual turbines at Difwind Ltd I are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this particular medium-voltage electric current is enhanced in voltage with a transformer for connection to the high voltage transmission system. Construction of a land-based wind farm requires setting up the collector system and substation, and probably roads to each turbine site.
