Dechang II (Ayue) wind farm is located in Sichuan, China. It was finished in 2013 and is owned by .
It is near Dechang County.
See below for data.
In most cases, economic wind machines require a wind speed of 4.5 m/s (16 km/h) or bigger.
A great position for a project like Dechang II (Ayue) could have a near constant flow of non-turbulent wind throughout the year, with a minimum chance of sudden effective bursts of wind. An essential aspect of turbine siting is furthermore admission to local demand or transmission capaDechang County.
Before building, Dechang II (Ayue) was most likely screened on the foundation of a wind atlas, and validated with wind specifications. However, Dechang II (Ayue) wind farm would have needed more than just meteorological data and measurements.
Site info around Dechang County is a major aspect in the development choice Winds around Dechang County are analysed for at least a year or so plus the development of detailed maps. Only then are wind turbines installed.
Altitude would also possess a part to performin a project like Dechang II (Ayue). This is due to drag The rise in velocity with altitude is most extraordinary close to the surface and is affected by geography, surface roughness, and upwind hurdles such as trees or buildings. Velocity increases with altitude and is also more obvious near land and is altered by topography, surface and obstructions.
Wind speeds growing with altitude is part of a wind energy law. This predicts wind speed rises with the 7th root of altitude. Doubling the altitude of a turbine, then, increases the anticipated wind speeds by 10%, and the anticipated power by 34%.
In general, a range of 7D (7 × Rotor Diameter of the Wind Turbine) is scheduled between each turbine in a fully developed wind farm. But this isn’t necessarily the way it is in hilly areas.
Individual turbines at Dechang II (Ayue) are interlocked with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this medium-voltage electric current is increased in voltage using a transformer for link with the high voltage transmission system. Construction of a land-based wind farm requires installation of the collector system and substation, and probably access roads to each and every turbine site.
