Callahan Divide wind project was installed in Texas, USA It was completed in 2005 and is owned by NextEra Energy.
It is near Taylor County.
See below for data.
In most cases, economic wind machines require a wind speed of 4.5 m/s (16 km/h) or higher.
The best location for something such as Callahan Divide would be a steady availability of non-turbulent wind. Additionally, you would not get a turbine NextEra Energy like NextEra Energy included if Callahan Divide was not built near local demand or transmission capaTaylor County.
During the planning stages the Callahan Divide wind farm would have been checked and authenticated through wind measurements. However, Callahan Divide wind farm might have needed more than just meteorological data and measurements.
Collection of site-specific data for wind speed and direction could have been vital to determining site potential in order to fund the project. Local winds are frequently supervised for a year or more, and detailed wind maps created before wind generators are installed.
Altitude would also possess a part to performin a project like Callahan Divide. This is because of drag The boost in velocity with altitude is most remarkable near the surface and is affected by geography, surface roughness, and upwind obstacles such as trees or buildings. Velocity increases with altitude and is also more pronounced near land and is changed by topography, surface and obstacles.
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 elevation of a turbine, then, raises the predicted wind speeds by 10%, and the predicted power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out to make sure they don’t affect one another. But micrositing increases placement, specifically in hilly areas.
Individual turbines at Callahan Divide are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, it medium-voltage electric energy is increased in voltage using a transformer for link with the high voltage transmission system. Development of a land-based wind farm requires installing of the collector system and substation, and perhaps access roads to each turbine site.
