It is near Yunlong, Dali.
See below for data.
As a rule, economic wind power generators require a wind speed of 4.5 m/s (16 km/h) or bigger.
The best place for a project like Caojian Liangzi I would have a near constant flow of non-turbulent wind throughout the year, having a minimum chances of abrupt effective bursts of wind. An essential aspect of turbine siting is furthermore admission to local demand or transmission capaYunlong, Dali.
Before building, Caojian Liangzi I was most likely screened on the foundation of a wind atlas, and validated with wind specifications. However, Caojian Liangzi I wind farm might have needed more than simply meteorological data and measurements.
Site information around Yunlong, Dali is a major element in the ‘development’ decision Winds around Yunlong, Dali are analysed for at least a year or so plus the introduction of detailed maps. Only then are wind turbines installed.
The wind hits more rapidly at greater altitudes because of the reduced influence of drag. The boost in velocity with altitude is most extraordinary near the surface and is affected by landscape, surface roughness, and upwind limitations such as trees or buildings. Velocity rises with altitude and is more evident near land and is altered by terrain, surface and obstructions.
Commonly, the rise of wind speeds with growing 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, enhances the predicted wind speeds by 10%, and the anticipated power by 34%.
In general, a length of 7D (7 × Rotor Diameter of the Wind Turbine) is defined between each turbine in a fully developed wind farm. But micrositing maximizes placement, particularly in hilly areas.
Individual turbines at Caojian Liangzi I are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, that medium-voltage electric energy is elevated in voltage using a transformer for link with the high voltage transmission system. Building of a land-based wind farm requires installing of the collector system and substation, and possibly access roads to every turbine site.
