Chaba wind farm is situated in Eastern Cape, South Africa. It was brought online in 2015 and is owned by .
It is near Great Kei Municipality.
See below for data.
In most cases, economic wind machines require a wind speed of 4.5 m/s (16 km/h) or greater.
A perfect location for a project like Chaba could have a near constant flow of non-turbulent wind year round, having a minimum probability of sudden potent bursts of wind. An essential aspect of turbine siting is moreover admission to local requirement or transmission capaGreat Kei Municipality.
During the planning stages the Chaba wind farm would have been checked and validated through wind measurements. Meteorological wind data alone is usually not ample for exact siting of a large wind power project.
Site data around Great Kei Municipality is a major element in the ‘development’ conclusion Local winds are often watched for a year or more, and comprehensive wind maps created before wind generators are installed.
The wind blows more quickly at higher altitudes because of the reduced influence of drag. The increase in velocity with altitude is most spectacular at the surface and is affected by landscape, surface roughness, and upwind obstructions such as trees or buildings. Velocity rises with altitude and is also more obvious near land and is changed by terrain, surface and obstructions.
Normally, the growth of wind speeds with growing elevation follows a wind profile power law, which anticipates that wind speed rises proportionately to the seventh root of altitude. Doubling the altitude of a turbine, then, enhances 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 defined between each turbine in a fully developed wind farm. But micrositing increases placement, specially in hilly areas.
Chaba turbines are linked via medium voltage lines and communications.
At a substation, it medium-voltage electric energy is enhanced in voltage with a transformer for link with the high voltage transmission system. Construction of a land-based wind farm requires setting up the collector system and substation, and perhaps access roads to each turbine site.
