Auwahi wind farm is situated in Hawaii, USA. It was in fact brought online in 2012 and is owned by Sempra Generation, BP Alternative Energy.
It is near Ulupalakua Ranch, about 10 miles south of Kula on the southeast coast of Maui.
See below for data.
In most cases, economic wind machines require a wind speed of 4.5 m/s (16 km/h) or more.
An ideal place for a project like Auwahi would have a near constant flow of non-turbulent wind throughout the year, having a minimum chance of abrupt powerful bursts of wind. An important factor of turbine siting is moreover admission to local requirement or transmission capaUlupalakua Ranch, about 10 miles south of Kula on the southeast coast of Maui.
During the planning stages the Auwahi wind farm would have been checked and validated through wind measurements. However, Auwahi wind farm might have needed more than merely meteorological data and measurements.
Collection of site-specific data for wind speed and direction could have been important to determining site potential in order to fund the project. Local winds are frequently examined for a year or more, and detailed wind maps created before wind generators are installed.
The wind blows sooner at greater altitudes due to the reduced effect of drag. The surge in velocity with altitude is most remarkable near the surface and is impacted by topography, surface roughness, and upwind limitations such as trees or buildings. Velocity grows with altitude and it is more pronounced near land and is changed by terrain, surface and obstacles.
Normally, 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 elevation of a turbine, then, boosts the anticipated wind speeds by 10%, and the expected 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. But micrositing optimizes placement, particularly in hilly areas.
Individual turbines at Auwahi are interlocked with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, it medium-voltage electric current is improved in voltage with a transformer for link with the high voltage transmission system. Construction of a land-based wind farm requires installing of the collector system and substation, and probably roads to each turbine site.
