De Bjirmen wind farm is located in Friesland, The Netherlands. It was finished in 1995 and is owned by .
It is near Oosterbierum.
See below for data.
Generally speaking, economic wind turbines require a wind speed of 4.5 m/s (16 km/h) or bigger.
The best destination for something such as De Bjirmen would be a steady supply of non-turbulent wind. An important factor of turbine siting is moreover admittance to local demand or transmission capaOosterbierum.
Before development, De Bjirmen was probably screened on the foundation of a wind atlas, and validated with wind measurements. Meteorological wind data alone is usually not enough for precise siting of a large wind power project.
Assortment of site-specific data for wind speed and direction would have been imperative to determining site potential to be able to fund the project. Winds around Oosterbierum are analysed for at least a year or so alongside the introduction of detailed maps. Only then are wind turbines installed.
Altitude would also have a part to playwithin a project like De Bjirmen. This is because of drag The boost in velocity with altitude is most dramatic near the surface and is affected by landscape, surface roughness, and upwind hurdles such as trees or buildings. Velocity rises with altitude and is more obvious near land and is transformed by topography, surface and limitations.
Wind speeds raising with altitude is part of a wind energy law. This anticipates wind speed rises with the 7th root of altitude. Doubling the height of a turbine, then, enhances the anticipated wind speeds by 10%, and the estimated power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they are spaced out so they don’t affect each other. But micrositing maximizes placement, specially in hilly areas.
Individual turbines at De Bjirmen are interconnected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this medium-voltage electric current is improved in voltage using a transformer for connection to the high voltage transmission system. Development of a land-based wind farm requires setting up the collector system and substation, and probably access roads to every turbine site.
