It is near Jianchuan.
See below for data.
Generally speaking, economic wind power generators require a wind speed of 4.5 m/s (16 km/h) or bigger.
The best destination for a project like Diannan could have a near constant flow of non-turbulent wind all year round, with a minimum likelihood of abrupt effective bursts of wind. Additionally, you would not get a turbine China Longyuan Power Group like China Longyuan Power Group included if Diannan was not built near local demand or transmission capaJianchuan.
Before building, Diannan was most likely screened on the basis of a wind atlas, and validated with wind measurements. Meteorological wind data alone is usually not enough for accurate siting of a large wind power project.
Collection of site-specific data for wind speed and direction would have been imperative to determining site potential to be able to finance the project. Winds around Jianchuan are evaluated for over a year or so alongside the development of detailed maps. Only then are wind turbines installed.
Altitude would also possess a part to playin a project like Diannan. This is due to drag The boost in velocity with altitude is most spectacular near the surface and is affected by landscape, surface roughness, and upwind limitations such as trees or buildings. Velocity increases with altitude and is also more pronounced near land and is transformed by terrain, surface and hurdles.
Sometimes, the increase of wind speeds with escalating elevation 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, enhances the expected wind speeds by 10%, and the anticipated power by 34%.
In general, a distance of 7D (7 × Rotor Diameter of the Wind Turbine) is defined between each turbine in a fully developed wind farm. But micrositing optimizes placement, particularly in hilly areas.
Diannan turbines are linked via medium voltage lines and communications.
At a substation, that medium-voltage electric current is enhanced in voltage using a transformer for connection to the high voltage transmission system. Development of a land-based wind farm requires installation of the collector system and substation, and perhaps access roads to every turbine site.
