It is near Weining County, Bijie City.
See below for data.
As a general rule, economic wind turbines require a wind speed of 4.5 m/s (16 km/h) or bigger.
An ideal destination for a project like Doukouzi would have a near constant flow of non-turbulent wind all year round, having a minimum likelihood of sudden potent bursts of wind. An essential aspect of turbine siting is also admission to local demand or transmission capaWeining County, Bijie City.
Before construction, Doukouzi was probably screened on the basis of a wind atlas, and validated with wind specifications. Meteorological wind data alone is usually not adequate for correct siting of a large wind power project.
Site info around Weining County, Bijie City would have been a major aspect in the development conclusion Local winds are often watched for a year or more, and detailed wind maps built before wind generators are installed.
The wind blows quicker at greater altitudes because of the reduced effect of drag. The rise in velocity with altitude is most extraordinary close to the surface and is impacted by geography, surface roughness, and upwind obstructions such as trees or buildings. Velocity rises with altitude and is also more evident near land and is altered by geography, surface and obstructions.
Wind speeds escalating with altitude is part of a wind energy law. This anticipates wind speed rises with the 7th root of altitude. Increasing the altitude of a turbine, then, boosts the expected wind speeds by 10%, and the estimated power by 34%.
In general, a distance of 7D (7 × Rotor Diameter of the Wind Turbine) is about between each turbine in a fully developed wind farm. But micrositing increases placement, particularly in hilly areas.
Doukouzi turbines are connected via medium voltage lines and communications.
At a substation, it medium-voltage electric current is increased in voltage with a transformer for link with the high voltage transmission system. Building of a land-based wind farm requires installation of the collector system and substation, and possibly access roads to each and every turbine site.
