Century expansion wind farm is situated in Iowa, USA. It was brought online in 2008 and is owned by MidAmerican Energy.
It is near .
See below for data.
As a general rule, economic wind turbines require a wind speed of 4.5 m/s (16 km/h) or higher.
The best location for something similar to Century expansion would be a steady availability of non-turbulent wind. An essential aspect of turbine siting is also admission to local requirement or transmission capa.
Before building, Century expansion was most likely screened on the basis of a wind atlas, and validated with wind measurements. Meteorological wind data alone is usually not adequate for exact siting of a large wind power project.
Site information around is a major element in the development final decision Winds around are evaluated for over a year or so alongside the introduction of detailed maps. Only then are wind turbines installed.
Altitude would also possess a part to performin a project like Century expansion. This is because of drag The rise in velocity with altitude is most spectacular near the surface and is impacted by geography, surface roughness, and upwind obstacles such as trees or buildings. Velocity rises with altitude and it is more distinct near land and is changed by topography, surface and obstructions.
Typically, the increase 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. Doubling the height of a turbine, then, boosts the predicted wind speeds by 10%, and the predicted power by 34%.
In general, a length of 7D (7 × Rotor Diameter of the Wind Turbine) is about between each turbine in a fully developed wind farm. But micrositing optimizes placement, particularly in hilly areas.
Century expansion turbines are linked via medium voltage lines and communications.
At a substation, it medium-voltage electric current is elevated in voltage using a transformer for link with the high voltage transmission system. Building of a land-based wind farm requires setting up the collector system and substation, and perhaps roads to each turbine site.
