Alto Douro – Armamar wind project was set up in Viseu, Portugal It was in fact brought online in 2010 and is owned by .
It is near São Martinho de Chãs, São Cosmado, Santa Cruz and Cimbres, municipality of Armamar.
See below for data.
As a rule, economic wind machines require a wind speed of 4.5 m/s (16 km/h) or larger.
The best location for something like Alto Douro – Armamar is a steady availability of non-turbulent wind. An important factor of turbine siting is moreover admission to local demand or transmission capaSão Martinho de Chãs, São Cosmado, Santa Cruz and Cimbres, municipality of Armamar.
During the planning stages the Alto Douro – Armamar wind farm would have been checked and authenticated through wind measurements. However, Alto Douro – Armamar wind farm would have needed more than simply meteorological data and measurements.
Collection of site-specific data for wind speed and direction would have been vital to determining site potential in order to fund the project. Local winds are frequently monitored for a year or more, and detailed wind maps created before wind generators are installed.
The wind hits quicker at greater altitudes because of the reduced influence of drag. The surge in velocity with altitude is most spectacular near the surface and is affected by landscape, surface roughness, and upwind obstacles such as trees or buildings. Velocity boosts with altitude and is also more obvious near land and is altered by terrain, surface and obstacles.
Sometimes, the growth of wind speeds with increasing height follows a wind profile power law, which forecasts that wind speed rises proportionately to the seventh root of altitude. Doubling the height of a turbine, then, raises the predicted wind speeds by 10%, and the predicted power by 34%.
In general, a distance of 7D (7 × Rotor Diameter of the Wind Turbine) is scheduled between each turbine in a fully developed wind farm. But micrositing optimizes placement, specially in hilly areas.
Individual turbines at Alto Douro – Armamar 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 enhanced in voltage with a transformer for link with the high voltage transmission system. Building of a land-based wind farm requires installing of the collector system and substation, and probably roads to every turbine site.
