Dishuihu wind farm is situated in Hebei, China. It was in fact brought online in 2010 and is owned by .
It is near Weichang, Chengde City.
See below for data.
As a rule, economic wind turbines require a wind speed of 4.5 m/s (16 km/h) or larger.
A great location for a project like Dishuihu would have a near constant flow of non-turbulent wind throughout the year, having a minimum probability of sudden powerful bursts of wind. An essential aspect of turbine siting is furthermore admittance to local demand or transmission capaWeichang, Chengde City.
Before development, Dishuihu was almost certainly 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.
Site data around Weichang, Chengde City would have been a major factor in the development final decision Winds around Weichang, Chengde City are evaluated for at least a year or so alongside the introduction of detailed maps. Only then are wind turbines installed.
Altitude would also have a part to playwithin a project like Dishuihu. This is due to drag The surge in velocity with altitude is most spectacular at the surface and is affected by geography, surface roughness, and upwind limitations such as trees or buildings. Velocity grows with altitude and is more pronounced near land and is changed by topography, surface and obstructions.
Wind speeds escalating with altitude is part of a wind energy law. This Hebeis wind speed rises with the 7th root of altitude. Doubling the elevation of a turbine, then, raises the expected 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, specially in hilly areas.
Individual turbines at Dishuihu are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this kind of medium-voltage electric energy is enhanced in voltage using a transformer for connection to the high voltage transmission system. Building of a land-based wind farm requires installing of the collector system and substation, and perhaps roads to each turbine site.
