It is near Laoting County.
See below for data.
Generally speaking, economic wind power generators require a wind speed of 4.5 m/s (16 km/h) or greater.
The best destination for a project like Daqinghe Yanchang would have a near constant flow of non-turbulent wind all year long, with a minimum likelihood of sudden potent bursts of wind. An essential aspect of turbine siting is also access to local demand or transmission capaLaoting County.
Before building, Daqinghe Yanchang was most likely screened on the foundation of a wind atlas, and validated with wind specifications. However, Daqinghe Yanchang wind farm would have needed more than merely meteorological data and measurements.
Site data around Laoting County is a major element in the ‘development’ conclusion Local winds are often checked for a year or more, and detailed wind maps constructed before wind generators are installed.
The wind blows swifter at greater altitudes due to the reduced effect of drag. The surge in velocity with altitude is most spectacular near the surface and is affected by landscape, surface roughness, and upwind obstructions such as trees or buildings. Velocity boosts with altitude and is also more distinct near land and is changed by terrain, surface and obstructions.
Wind speeds raising with altitude is part of a wind energy law. This forecasts wind speed rises with the 7th root of altitude. Increasing the elevation of a turbine, then, raises the anticipated wind speeds by 10%, and the anticipated power by 34%.
In general, a length of 7D (7 × Rotor Diameter of the Wind Turbine) is scheduled between each turbine in a fully developed wind farm. But micrositing optimizes placement, specifically in hilly areas.
Daqinghe Yanchang turbines are connected via medium voltage lines and communications.
At a substation, this medium-voltage electric current is elevated in voltage using a transformer for link with the high voltage transmission system. Building of a land-based wind farm requires installing of the collector system and substation, and possibly access roads to each turbine site.
