Dorper wind farm is situated in Eastern Cape, South Africa. It was created in 2011 and is owned by Inkwanca Municipality.
It is near Molteno.
See below for data.
Wind farms, as a general rule require wind speeds of 4.5 metres per second or more.
The best destination for a project like Dorper could have a near constant flow of non-turbulent wind all year long, having a minimum likelihood of abrupt potent bursts of wind. An important factor of turbine siting is moreover admittance to local demand or transmission capaMolteno.
Before development, Dorper was probably screened on the basis of a wind atlas, and validated with wind measurements. However, Dorper wind farm might have needed more than just meteorological data and measurements.
Assortment of site-specific data for wind speed and direction might have been vital to determining site potential to be able to finance the project. Local winds are frequently checked for a year or more, and detailed wind maps built before wind generators are set up.
Altitude would also have a part to playwithin a project like Dorper. This is due to drag The rise in velocity with altitude is most extraordinary near the surface and is impacted by topography, surface roughness, and upwind obstacles such as trees or buildings. Velocity boosts with altitude and is also more evident near land and is altered by terrain, surface and obstacles.
Wind speeds increasing with altitude is part of a wind energy law. This anticipates wind speed rises with the 7th root of altitude. Doubling the altitude of a turbine, then, boosts 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 defined between each turbine in a fully developed wind farm. But micrositing increases placement, specially in hilly areas.
Dorper turbines are related via medium voltage lines and communications.
At a substation, this medium-voltage electric current is increased in voltage with a transformer for connection to the high voltage transmission system. Construction of a land-based wind farm requires setting up the collector system and substation, and perhaps roads to each and every turbine site.
