Dahai Liangzi I wind farm is situated in Yunnan, China. It was created in 2014 and is owned by CSIC Chongqing Haizhuang.
It is near Dahai Village, Huize County.
See below for data.
Wind farms, as a general rule require wind speeds of 4.5 metres per second or higher.
The best place for a project like Dahai Liangzi I might have a near constant flow of non-turbulent wind year round, with a minimum chances of abrupt powerful bursts of wind. An important factor of turbine siting is also admission to local requirement or transmission capaDahai Village, Huize County.
During the planning stages the Dahai Liangzi I wind farm would’ve been checked and confirmed through wind measurements. However, Dahai Liangzi I wind farm would have needed more than merely meteorological data and measurements.
Site data around Dahai Village, Huize County would have been a major factor in the ‘development’ final decision Winds around Dahai Village, Huize County are examined for over a year or so alongside the introduction of detailed maps. Only then are wind turbines installed.
The wind blows swifter at higher altitudes because of the reduced effect of drag. The boost in velocity with altitude is most remarkable at the surface and is affected by topography, 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 topography, surface and obstructions.
Generally, the rise of wind speeds with raising 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 expected wind speeds by 10%, and the estimated power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they are spaced out to make sure they don’t affect each other. But micrositing increases placement, specifically in hilly areas.
Dahai Liangzi I turbines are related via medium voltage lines and communications.
At a substation, this medium-voltage electric energy is elevated in voltage with a transformer for link with the high voltage transmission system. Development of a land-based wind farm requires setting up the collector system and substation, and possibly roads to every turbine site.
