Day County wind farm is situated in South Dakota, USA. It was brought online in 2010 and is owned by NextEra Energy.
It is near Day County.
See below for data.
For the most part, economic wind turbines require a wind speed of 4.5 m/s (16 km/h) or higher.
A great position for a project like Day County could have a near constant flow of non-turbulent wind year round, having a minimum chances of abrupt potent bursts of wind. An essential aspect of turbine siting is also admission to local requirement or transmission capaDay County.
During the planning stages the Day County wind farm would’ve been checked and endorsed through wind measurements. However, Day County wind farm would have needed more than merely meteorological data and measurements.
Collection of site-specific data for wind speed and direction might have been essential to determining site potential to be able to fund the project. Winds around Day County are evaluated for at least a year or so alongside the creation of detailed maps. Only then are wind turbines installed.
The wind blows faster at greater altitudes due to the reduced influence of drag. The increase in velocity with altitude is most dramatic at the surface and is affected by geography, surface roughness, and upwind hurdles such as trees or buildings. Velocity boosts with altitude and is more evident near land and is transformed by landscape, surface and limitations.
Sometimes, the rise of wind speeds with escalating height follows a wind profile power law, which predicts that wind speed rises proportionately to the seventh root of altitude. Increasing the height of a turbine, then, boosts the expected wind speeds by 10%, and the anticipated power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they are spaced out so they really don’t affect one another. But micrositing maximizes placement, specially in hilly areas.
Day County turbines are connected via medium voltage lines and communications.
At a substation, that medium-voltage electric energy is increased in voltage using a transformer for connection to the high voltage transmission system. Building of a land-based wind farm requires installing of the collector system and substation, and probably access roads to each turbine site.
