It is near Aihui District, Heihe.
See below for data.
Typically, economic wind generators require a wind speed of 4.5 m/s (16 km/h) or bigger.
The best position for a project like Daheishan II might have a near constant flow of non-turbulent wind all year round, with a minimum chance of sudden potent bursts of wind. An important factor of turbine siting is moreover access to local requirement or transmission capaAihui District, Heihe.
Before building, Daheishan II was most likely screened on the foundation of a wind atlas, and validated with wind specifications. However, Daheishan II wind farm would have needed more than merely meteorological data and measurements.
Site info around Aihui District, Heihe is a major aspect in the development choice Winds around Aihui District, Heihe are examined for over a year or so alongside the introduction of detailed maps. Only then are wind turbines installed.
The wind hits quicker at greater altitudes because of the reduced influence of drag. The boost in velocity with altitude is most dramatic near the surface and is affected by geography, surface roughness, and upwind obstructions such as trees or buildings. Velocity increases with altitude and is more pronounced near land and is changed by landscape, surface and obstructions.
Normally, the growth of wind speeds with raising elevation 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, boosts the predicted wind speeds by 10%, and the expected power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out so they really don’t affect each other. However this might not be the way it is in hilly areas.
Daheishan II turbines are related via medium voltage lines and communications.
At a substation, this medium-voltage electric energy is improved in voltage using a transformer for link with the high voltage transmission system. Development of a land-based wind farm requires installing of the collector system and substation, and perhaps roads to each and every turbine site.
