Dingbian Zhangjiashan I wind project was set up in Shaanxi, China It was finished in 2011 and is owned by .
It is near Yulin.
See below for data.
Wind farms, as a general rule call for wind speeds of 4.5 metres per second or more.
A perfect location for a project like Dingbian Zhangjiashan I might have a near constant flow of non-turbulent wind all year long, with a minimum chances of sudden powerful bursts of wind. An important factor of turbine siting is moreover admittance to local requirement or transmission capaYulin.
Before building, Dingbian Zhangjiashan I was most likely screened on the foundation of a wind atlas, and validated with wind measurements. Meteorological wind data alone is usually not enough for accurate siting of a large wind power project.
Collection of site-specific data for wind speed and direction could have been imperative to determining site potential to be able to finance the project. Winds around Yulin are analysed for at least a year or so plus the introduction of detailed maps. Only then are wind turbines installed.
Altitude would also have a part to playin a project like Dingbian Zhangjiashan I. This is because of drag The boost 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 more distinct near land and is changed by terrain, surface and hurdles.
Ordinarily, the increase of wind speeds with growing height follows a wind profile power law, which predicts that wind speed rises proportionately to the seventh root of altitude. Doubling the altitude of a turbine, then, raises the anticipated wind speeds by 10%, and the expected power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they are spaced out so they don’t affect one another. But micrositing increases placement, particularly in hilly areas.
Dingbian Zhangjiashan I turbines are related via medium voltage lines and communications.
At a substation, it medium-voltage electric energy is enhanced in voltage using a transformer for link with the high voltage transmission system. Development of a land-based wind farm requires installation of the collector system and substation, and perhaps roads to each and every turbine site.
