It is near Dafeng.
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 something such as Dafeng II (Longyuan) is a steady supply of non-turbulent wind. Additionally, you would not get a turbine China Longyuan Power Group like China Longyuan Power Group included if Dafeng II (Longyuan) was not built near local demand or transmission capaDafeng.
Before construction, Dafeng II (Longyuan) was almost certainly screened on the basis of a wind atlas, and validated with wind specifications. However, Dafeng II (Longyuan) wind farm might have needed more than just meteorological data and measurements.
Site information around Dafeng is a major aspect in the development decision Winds around Dafeng are examined for at least a year or so plus the introduction of detailed maps. Only then are wind turbines installed.
The wind hits sooner at higher altitudes as a result of reduced influence of drag. The rise in velocity with altitude is most remarkable close to the surface and is affected by landscape, surface roughness, and upwind obstacles such as trees or buildings. Velocity increases with altitude and is also more obvious near land and is altered by landscape, surface and obstructions.
Normally, the rise of wind speeds with increasing height follows a wind profile power law, which predicts that wind speed rises proportionately to the seventh root of altitude. Increasing the height of a turbine, then, boosts the predicted wind speeds by 10%, and the estimated power by 34%.
In general, a range of 7D (7 × Rotor Diameter of the Wind Turbine) is set between each turbine in a fully developed wind farm. However this isn’t necessarily the situation in hilly areas.
Individual turbines at Dafeng II (Longyuan) 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 current is increased in voltage using 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 probably roads to each and every turbine site.
