Belrain wind farm is located in Lorraine, France. It was finished in 2011 and is owned by Allianz.
It is near Belrain.
See below for data.
Wind farms, as a general rule need wind speeds of 4.5 metres per second or higher.
An ideal destination for a project like Belrain could have a near constant flow of non-turbulent wind throughout the year, having a minimum likelihood of abrupt powerful bursts of wind. An important factor of turbine siting is also admission to local demand or transmission capaBelrain.
During the planning stages the Belrain wind farm would have been checked and endorsed through wind measurements. However, Belrain wind farm would have needed more than just meteorological data and measurements.
Site info around Belrain would have been a major element in the ‘development’ choice Local winds are often examined for a year or more, and comprehensive wind maps constructed before wind generators are installed.
The wind blows more rapidly at higher altitudes because of the reduced effect of drag. The rise in velocity with altitude is most dramatic near the surface and is impacted by landscape, surface roughness, and upwind hurdles such as trees or buildings. Velocity increases with altitude and is also more obvious near land and is transformed by terrain, surface and limitations.
Almost always, the growth of wind speeds with escalating height follows a wind profile power law, which anticipates that wind speed rises proportionately to the seventh root of altitude. Increasing the altitude of a turbine, then, enhances the expected 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 that they don’t affect each other. But micrositing optimizes placement, specially in hilly areas.
Individual turbines at Belrain are interconnected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this kind of medium-voltage electric current is enhanced in voltage using 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 possibly roads to every turbine site.
