It is near Guyuan County.
See below for data.
For the most part, economic wind turbines require a wind speed of 4.5 m/s (16 km/h) or more.
An ideal position for a project like Danaobao II might have a near constant flow of non-turbulent wind all year round, with a minimum probability of abrupt effective bursts of wind. An important factor of turbine siting is also admission to local requirement or transmission capaGuyuan County.
During the planning stages the Danaobao II wind farm would’ve been checked and confirmed through wind measurements. However, Danaobao II wind farm would have needed more than just meteorological data and measurements.
Site data around Guyuan County would have been a major factor in the development choice Local winds are frequently checked for a year or more, and comprehensive wind maps constructed before wind generators are installed.
The wind blows sooner at greater altitudes as a result of reduced effect of drag. The rise in velocity with altitude is most extraordinary at the surface and is impacted by geography, surface roughness, and upwind limitations such as trees or buildings. Velocity boosts with altitude and it is more distinct near land and is altered by terrain, surface and hurdles.
Commonly, the growth of wind speeds with escalating height follows a wind profile power law, which forecasts that wind speed rises proportionately to the seventh root of altitude. Increasing the altitude of a turbine, then, raises the anticipated wind speeds by 10%, and the predicted power by 34%.
In general, a range of 7D (7 × Rotor Diameter of the Wind Turbine) is defined between each turbine in a fully developed wind farm. However this isn’t necessarily the situation in hilly areas.
Danaobao II turbines are linked via medium voltage lines and communications.
At a substation, that medium-voltage electric energy is improved 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 turbine site.
