Arnold wind project was installed in Minnesota, USA It was completed in 2005 and is owned by .
It is near Wilmont.
See below for data.
As a general rule, economic wind machines require a wind speed of 4.5 m/s (16 km/h) or more.
An ideal place for a project like Arnold could have a near constant flow of non-turbulent wind all year round, having a minimum chances of abrupt effective bursts of wind. An important factor of turbine siting is also admittance to local requirement or transmission capaWilmont.
During the planning stages the Arnold wind farm would have been checked and authenticated through wind measurements. However, Arnold wind farm might have needed more than merely meteorological data and measurements.
Collection of site-specific data for wind speed and direction could have been imperative to determining site potential in order to finance the project. Winds around Wilmont are analysed for over a year or so plus the development of detailed maps. Only then are wind turbines installed.
The wind blows more quickly at higher altitudes due to the reduced influence of drag. The boost 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 is also more evident near land and is transformed by geography, surface and obstacles.
Wind speeds increasing with altitude is part of a wind energy law. This Minnesotas wind speed rises with the 7th root of altitude. Increasing the elevation of a turbine, then, enhances the anticipated 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 in order that they don’t affect one another. But micrositing maximizes placement, specifically in hilly areas.
Arnold turbines are related via medium voltage lines and communications.
At a substation, this kind of medium-voltage electric energy is increased 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 possibly access roads to each and every turbine site.
