Cookhouse wind farm is located in Eastern Cape, South Africa. It was finished in 2015 and is owned by African Clean Energy Developments (ACED).
It is near Cacadu.
See below for data.
Typically, economic wind power generators require a wind speed of 4.5 m/s (16 km/h) or bigger.
An ideal position for a project like Cookhouse could have a near constant flow of non-turbulent wind all year round, with a minimum probability of sudden effective bursts of wind. An essential aspect of turbine siting is furthermore admittance to local requirement or transmission capaCacadu.
During the planning stages the Cookhouse 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.
Collection of site-specific data for wind speed and direction could have been imperative to determining site potential to be able to fund the project. Winds around Cacadu are evaluated for at least a year or so plus the introduction of detailed maps. Only then are wind turbines installed.
Altitude would also possess a part to playwithin a project like Cookhouse. This is because of drag The boost in velocity with altitude is most spectacular close to the surface and is affected by topography, surface roughness, and upwind obstacles such as trees or buildings. Velocity rises with altitude and is more obvious near land and is transformed by topography, surface and obstructions.
Wind speeds increasing with altitude is part of a wind energy law. This Eastern Capes wind speed rises with the 7th root of altitude. Doubling the altitude of a turbine, then, enhances 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 are spaced out so they don’t affect one another. However this is not always the situation in hilly areas.
Cookhouse turbines are connected via medium voltage lines and communications.
At a substation, that medium-voltage electric current is improved in voltage with 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 possibly access roads to each turbine site.
