Baolian wind farm is situated in Hunan, China. It was completed in 2014 and is owned by Sinohydro Corporation.
It is near Longhui, Shaoyang.
See below for data.
In most cases, economic wind power generators require a wind speed of 4.5 m/s (16 km/h) or more.
The best place for a project like Baolian would have a near constant flow of non-turbulent wind year round, having a minimum probability of sudden potent bursts of wind. Additionally, you would not get a turbine Sinohydro Corporation like Sinohydro Corporation included if Baolian was not built near local demand or transmission capaLonghui, Shaoyang.
Before construction, Baolian was probably screened on the basis of a wind atlas, and validated with wind measurements. However, Baolian wind farm might have needed more than just meteorological data and measurements.
Collection of site-specific data for wind speed and direction could have been imperative to determining site potential as a way to finance the project. Winds around Longhui, Shaoyang are examined for at least a year or so alongside the creation of detailed maps. Only then are wind turbines installed.
Altitude would also have a part to playin a project like Baolian. This is due to drag The increase in velocity with altitude is most dramatic at the surface and is impacted by landscape, surface roughness, and upwind obstructions such as trees or buildings. Velocity rises with altitude and is also more pronounced near land and is changed by geography, surface and obstructions.
Wind speeds raising 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, enhances 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 about between each turbine in a fully developed wind farm. But micrositing optimizes placement, particularly in hilly areas.
Baolian turbines are connected via medium voltage lines and communications.
At a substation, it medium-voltage electric energy is improved in voltage with a transformer for link with the high voltage transmission system. Building of a land-based wind farm requires setting up the collector system and substation, and probably access roads to each turbine site.
