Alegria II wind farm is located in Río Grande do Norte, Brazil. It was completed in 2012 and is owned by Multiner, Eólica Tecnologia.
It is near Guamare.
See below for data.
For the most part, economic wind generators require a wind speed of 4.5 m/s (16 km/h) or larger.
The very best location for something such as Alegria II is a steady supply of non-turbulent wind. An essential aspect of turbine siting is also access to local demand or transmission capaGuamare.
During the planning stages the Alegria II wind farm would’ve been checked and validated through wind measurements. Meteorological wind data alone is usually not sufficient for accurate siting of a large wind power project.
Assortment of site-specific data for wind speed and direction might have been important to determining site potential as a way to finance the project. Local winds are frequently watched for a year or more, and detailed wind maps constructed before wind generators are set up.
The wind hits more rapidly at higher altitudes due to the reduced effect of drag. The increase in velocity with altitude is most spectacular near the surface and is affected by geography, surface roughness, and upwind limitations such as trees or buildings. Velocity grows with altitude and is more obvious near land and is changed by terrain, surface and obstacles.
Wind speeds growing with altitude is part of a wind energy law. This anticipates wind speed rises with the 7th root of altitude. Increasing the height of a turbine, then, increases the expected wind speeds by 10%, and the estimated power by 34%.
In general, a distance of 7D (7 × Rotor Diameter of the Wind Turbine) is about between each turbine in a fully developed wind farm. But this might not be the case in hilly areas.
Individual turbines at Alegria II 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 elevated in voltage using a transformer for connection to the high voltage transmission system. Construction of a land-based wind farm requires installing of the collector system and substation, and probably access roads to each turbine site.
