Changshan wind farm is situated in Anhui, China. It was completed in 2015 and is owned by Jilin Electric Power Company.
It is near Nanqiao, Chuzhou.
See below for data.
Wind farms, as a general rule need wind speeds of 4.5 metres per second or more.
The very best destination for something such as Changshan is a steady availability of non-turbulent wind. An important factor of turbine siting is furthermore admission to local requirement or transmission capaNanqiao, Chuzhou.
During the planning stages the Changshan wind farm would have been checked and endorsed through wind measurements. However, Changshan wind farm might have needed more than simply meteorological data and measurements.
Site info around Nanqiao, Chuzhou is a major aspect in the ‘development’ choice Local winds are often examined for a year or more, and detailed wind maps built before wind generators are installed.
Altitude would also have a part to performwithin a project like Changshan. This is due to drag The boost in velocity with altitude is most dramatic at the surface and is impacted by landscape, surface roughness, and upwind obstructions such as trees or buildings. Velocity boosts with altitude and is more pronounced near land and is altered by topography, surface and obstacles.
Usually, the rise of wind speeds with raising elevation follows a wind profile power law, which forecasts that wind speed rises proportionately to the seventh root of altitude. Doubling the height of a turbine, then, enhances the predicted wind speeds by 10%, and the expected power by 34%.
In general, a distance of 7D (7 × Rotor Diameter of the Wind Turbine) is scheduled between each turbine in a fully developed wind farm. However this may not be the situation in hilly areas.
Individual turbines at Changshan are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, that medium-voltage electric current is increased in voltage with a transformer for link with the high voltage transmission system. Building of a land-based wind farm requires installing of the collector system and substation, and perhaps roads to every turbine site.
