It is near Xiaochang County, Xiaogan.
See below for data.
As a general rule, economic wind power generators require a wind speed of 4.5 m/s (16 km/h) or greater.
The best destination for something such as Dawushan is a steady availability of non-turbulent wind. Additionally, you would not get a turbine China Power Investment Corporation like China Power Investment Corporation involved if Dawushan was not built near local demand or transmission capaXiaochang County, Xiaogan.
During the planning stages the Dawushan wind farm would have been checked and confirmed through wind measurements. However, Dawushan wind farm might have needed more than simply meteorological data and measurements.
Collection of site-specific data for wind speed and direction would have been crucial to determining site potential in order to finance the project. Winds around Xiaochang County, Xiaogan are analysed for at least a year or so alongside the creation of detailed maps. Only then are wind turbines installed.
Altitude would also have a part to performwithin a project like Dawushan. This is due to drag The increase in velocity with altitude is most spectacular near the surface and is impacted by landscape, surface roughness, and upwind obstructions such as trees or buildings. Velocity increases with altitude and it is more pronounced near land and is changed by geography, surface and obstacles.
Ordinarily, the rise of wind speeds with raising elevation follows a wind profile power law, which predicts that wind speed rises proportionately to the seventh root of altitude. Doubling the elevation of a turbine, then, enhances the expected wind speeds by 10%, and the estimated 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. But micrositing increases placement, specifically in hilly areas.
Individual turbines at Dawushan are interconnected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this medium-voltage electric energy is elevated in voltage with a transformer for link with the high voltage transmission system. Construction of a land-based wind farm requires setting up the collector system and substation, and possibly access roads to each turbine site.
