Dongbaishan I wind farm is situated in Zhejiang, China. It was completed in 2010 and is owned by Dongyang Wind Power Development.
It is near Dongyang, Jinhua.
See below for data.
As a general rule, economic wind machines require a wind speed of 4.5 m/s (16 km/h) or higher.
The best location for something similar to Dongbaishan I is a steady supply of non-turbulent wind. Additionally, you wouldn’t get a turbine Dongyang Wind Power Development like Dongyang Wind Power Development involved if Dongbaishan I was not built near local demand or transmission capaDongyang, Jinhua.
Before building, Dongbaishan I was almost certainly screened on the basis of a wind atlas, and validated with wind specifications. Meteorological wind data alone is usually not ample for accurate siting of a large wind power project.
Site information around Dongyang, Jinhua would have been a major aspect in the development final decision Winds around Dongyang, Jinhua are examined for at least a year or so plus the creation of detailed maps. Only then are wind turbines installed.
The wind blows more rapidly at higher altitudes due to the reduced influence of drag. The rise 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 grows with altitude and it is more distinct near land and is changed by landscape, surface and limitations.
Commonly, the growth of wind speeds with increasing height follows a wind profile power law, which anticipates that wind speed rises proportionately to the seventh root of altitude. Doubling the height of a turbine, then, raises the expected wind speeds by 10%, and the predicted power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out so they don’t affect each other. But this is not always the case in hilly areas.
Individual turbines at Dongbaishan I are connected 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 connection to the high voltage transmission system. Development of a land-based wind farm requires installing of the collector system and substation, and probably roads to every turbine site.
