It is near Huanan County.
See below for data.
Wind farms, as a general rule require wind speeds of 4.5 metres per second or more.
The best place for a project like Dajiazishan might have a near constant flow of non-turbulent wind year round, having a minimum chance of sudden effective bursts of wind. Additionally, you wouldn’t get a turbine China Datang Corporation (CDT) like China Datang Corporation (CDT) included if Dajiazishan was not built near local demand or transmission capaHuanan County.
Before development, Dajiazishan was almost certainly screened on the foundation of a wind atlas, and validated with wind measurements. However, Dajiazishan wind farm might have needed more than just meteorological data and measurements.
Assortment of site-specific data for wind speed and direction could have been imperative to determining site potential to be able to finance the project. Local winds are often watched for a year or more, and comprehensive wind maps built before wind generators are installed.
The wind hits quicker at higher altitudes due to the reduced effect of drag. The surge in velocity with altitude is most extraordinary close to the surface and is impacted by topography, surface roughness, and upwind obstacles such as trees or buildings. Velocity grows with altitude and is also more pronounced near land and is changed by terrain, surface and obstacles.
Commonly, the rise of wind speeds with increasing height follows a wind profile power law, which forecasts that wind speed rises proportionately to the seventh root of altitude. Increasing the height of a turbine, then, enhances the predicted wind speeds by 10%, and the estimated power by 34%.
In general, a distance of 7D (7 × Rotor Diameter of the Wind Turbine) is set between each turbine in a fully developed wind farm. But micrositing increases placement, specifically in hilly areas.
Dajiazishan turbines are related via medium voltage lines and communications.
At a substation, that medium-voltage electric current is improved in voltage using 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.
