Dechang I (Mali) wind project was installed in Sichuan, China It was finished in 2011 and is owned by Dechang Windpower Development Co.
It is near Dechang County.
See below for data.
In most cases, economic wind turbines require a wind speed of 4.5 m/s (16 km/h) or greater.
The best place for a project like Dechang I (Mali) could have a near constant flow of non-turbulent wind throughout the year, with a minimum probability of abrupt effective bursts of wind. Additionally, you would not get a turbine Dechang Windpower Development Co like Dechang Windpower Development Co involved if Dechang I (Mali) was not built near local demand or transmission capaDechang County.
Before development, Dechang I (Mali) was almost certainly screened on the foundation of a wind atlas, and validated with wind measurements. Meteorological wind data alone is usually not adequate for correct siting of a large wind power project.
Site information around Dechang County is a major factor in the ‘development’ decision Local winds are often supervised for a year or more, and detailed wind maps built before wind generators are set up.
The wind hits quicker at higher altitudes because of the reduced influence of drag. The increase in velocity with altitude is most dramatic close to the surface and is impacted by topography, surface roughness, and upwind limitations such as trees or buildings. Velocity boosts with altitude and it is more distinct near land and is changed by geography, surface and limitations.
Wind speeds increasing with altitude is part of a wind energy law. This anticipates wind speed rises with the 7th root of altitude. Doubling the elevation of a turbine, then, increases the anticipated wind speeds by 10%, and the anticipated power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out so they don’t affect each other. But this isn’t necessarily the way it is in hilly areas.
Individual turbines at Dechang I (Mali) are interlocked with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, this particular medium-voltage electric current is elevated 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 access roads to each and every turbine site.
