Cruz Alta wind farm is situated in South, Brazil. It was finished in 2011 and is owned by Cruz Alta Energia Eolica.
It is near Agua Doce, Santa Catarina.
See below for data.
As a rule, economic wind power generators require a wind speed of 4.5 m/s (16 km/h) or greater.
The best location for a project like Cruz Alta might have a near constant flow of non-turbulent wind throughout the year, having a minimum chance of sudden effective bursts of wind. An essential aspect of turbine siting is also admittance to local demand or transmission capaAgua Doce, Santa Catarina.
Before development, Cruz Alta was most likely screened on the basis of a wind atlas, and validated with wind measurements. Meteorological wind data alone is usually not enough for accurate siting of a large wind power project.
Collection of site-specific data for wind speed and direction could have been imperative to determining site potential in order to finance the project. Local winds are frequently supervised for a year or more, and detailed wind maps constructed before wind generators are installed.
Altitude would also have a part to playin a project like Cruz Alta. This is due to drag The boost in velocity with altitude is most extraordinary at the surface and is impacted by landscape, surface roughness, and upwind obstructions such as trees or buildings. Velocity increases with altitude and it is more obvious near land and is altered by terrain, surface and limitations.
Wind speeds escalating with altitude is part of a wind energy law. This predicts wind speed rises with the 7th root of altitude. Increasing the height of a turbine, then, enhances the expected wind speeds by 10%, and the anticipated 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. But micrositing maximizes placement, specially in hilly areas.
Individual turbines at Cruz Alta are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this medium-voltage electric current is increased in voltage using a transformer for link with the high voltage transmission system. Building of a land-based wind farm requires installation of the collector system and substation, and probably access roads to every turbine site.
