Crockahenny wind farm is situated in Donegal, Ireland. It was finished in 1998 and is owned by ESB, Enercon.
It is near Buncrana.
See below for data.
For the most part, economic wind machines require a wind speed of 4.5 m/s (16 km/h) or larger.
The best location for something similar to Crockahenny would be a steady supply of non-turbulent wind. Additionally, you would not get a turbine ESB, Enercon like ESB, Enercon associated if Crockahenny was not built near local demand or transmission capaBuncrana.
During the planning stages the Crockahenny wind farm would’ve been checked and confirmed through wind measurements. Meteorological wind data alone is usually not adequate for correct siting of a large wind power project.
Collection of site-specific data for wind speed and direction could have been vital to determining site potential in order to finance the project. Local winds are often supervised for a year or more, and detailed wind maps built before wind generators are set up.
The wind blows faster at greater altitudes because of the reduced effect of drag. The surge in velocity with altitude is most spectacular at the surface and is impacted by topography, surface roughness, and upwind obstructions such as trees or buildings. Velocity grows with altitude and it is more pronounced near land and is changed by terrain, surface and obstructions.
Wind speeds increasing with altitude is part of a wind energy law. This Donegals wind speed rises with the 7th root of altitude. Increasing the height of a turbine, then, enhances the anticipated wind speeds by 10%, and the anticipated power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out so that they don’t affect each other. However this is not always the situation in hilly areas.
Crockahenny turbines are related via medium voltage lines and communications.
At a substation, that medium-voltage electric energy is elevated in voltage with a transformer for connection to the high voltage transmission system. Construction of a land-based wind farm requires installing of the collector system and substation, and probably access roads to each and every turbine site.
