Cagliari II wind project was set up in Sardinia, Italy It was completed in 2012 and is owned by .
It is near municipalities of Uta and Assemini.
See below for data.
Generally speaking, economic wind generators require a wind speed of 4.5 m/s (16 km/h) or larger.
A perfect destination for a project like Cagliari II could have a near constant flow of non-turbulent wind year round, with a minimum likelihood of abrupt effective bursts of wind. Additionally, you wouldn’t get a turbine like included if Cagliari II was not built near local demand or transmission capamunicipalities of Uta and Assemini.
During the planning stages the Cagliari II wind farm would’ve been checked and validated through wind measurements. However, Cagliari II wind farm would have needed more than merely meteorological data and measurements.
Site information around municipalities of Uta and Assemini is a major aspect in the ‘development’ decision Local winds are frequently supervised for a year or more, and comprehensive wind maps made before wind generators are set up.
The wind hits quicker at greater altitudes because of the reduced effect of drag. The boost in velocity with altitude is most extraordinary at the surface and is impacted by landscape, surface roughness, and upwind obstacles such as trees or buildings. Velocity grows with altitude and is more obvious near land and is altered by terrain, surface and hurdles.
Typically, the growth of wind speeds with escalating elevation follows a wind profile power law, which anticipates that wind speed rises proportionately to the seventh root of altitude. Increasing the height of a turbine, then, increases the expected wind speeds by 10%, and the estimated power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they are spaced out so they really don’t affect each other. However this may not be the case in hilly areas.
Individual turbines at Cagliari II are interlocked with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this particular medium-voltage electric energy is increased in voltage using a transformer for link with the high voltage transmission system. Construction of a land-based wind farm requires installation of the collector system and substation, and probably roads to each turbine site.
