Dabieshan wind farm is situated in Henan, China. It was in fact brought online in 2014 and is owned by Hongchang Power.
It is near Xinyang.
See below for data.
As a general rule, economic wind machines require a wind speed of 4.5 m/s (16 km/h) or greater.
A perfect place for a project like Dabieshan could have a near constant flow of non-turbulent wind year round, having a minimum chance of abrupt powerful bursts of wind. An essential aspect of turbine siting is furthermore admission to local requirement or transmission capaXinyang.
During the planning stages the Dabieshan wind farm would’ve been checked and authenticated through wind measurements. Meteorological wind data alone is usually not enough for correct siting of a large wind power project.
Site information around Xinyang is a major aspect in the ‘development’ conclusion Local winds are often monitored for a year or more, and comprehensive wind maps constructed before wind generators are set up.
The wind blows sooner at greater altitudes because of the reduced influence of drag. The rise in velocity with altitude is most spectacular at the surface and is impacted by geography, surface roughness, and upwind obstacles such as trees or buildings. Velocity grows with altitude and it is more pronounced near land and is transformed by terrain, surface and obstacles.
Wind speeds raising with altitude is part of a wind energy law. This Henans wind speed rises with the 7th root of altitude. Doubling the elevation of a turbine, then, raises the predicted 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 really don’t affect one another. But this is not always the way it is in hilly areas.
Individual turbines at Dabieshan are interconnected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, that medium-voltage electric energy is improved in voltage with a transformer for link with the high voltage transmission system. Construction of a land-based wind farm requires setting up the collector system and substation, and probably roads to each turbine site.
