It is near Mengzi, south east of Yunnan Province.
See below for data.
Wind farms, as a general rule require wind speeds of 4.5 metres per second or more.
The best location for a project like Duogu would have a near constant flow of non-turbulent wind throughout the year, with a minimum probability of sudden powerful bursts of wind. An essential aspect of turbine siting is moreover admittance to local requirement or transmission capaMengzi, south east of Yunnan Province.
Before development, Duogu was most likely screened on the foundation of a wind atlas, and validated with wind specifications. Meteorological wind data alone is usually not adequate for precise siting of a large wind power project.
Collection of site-specific data for wind speed and direction might have been essential to determining site potential to be able to fund the project. Winds around Mengzi, south east of Yunnan Province are analysed for at least a year or so alongside the creation of detailed maps. Only then are wind turbines installed.
Altitude would also possess a part to performwithin a project like Duogu. This is because of drag The rise in velocity with altitude is most spectacular at the surface and is affected by geography, surface roughness, and upwind obstacles such as trees or buildings. Velocity increases with altitude and it is more pronounced near land and is altered by geography, surface and obstacles.
Wind speeds growing with altitude is part of a wind energy law. This forecasts wind speed rises with the 7th root of altitude. Increasing the height of a turbine, then, increases the expected wind speeds by 10%, and the expected power by 34%.
In general, a distance of 7D (7 × Rotor Diameter of the Wind Turbine) is scheduled between each turbine in a fully developed wind farm. However this may not be the way it is in hilly areas.
Individual turbines at Duogu are interlocked with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this kind of medium-voltage electric energy is enhanced in voltage with a transformer for connection to the high voltage transmission system. Development of a land-based wind farm requires setting up the collector system and substation, and perhaps access roads to every turbine site.
