Dongying Hekou wind farm is situated in Shandong, China. It was finished in 2009 and is owned by CLP Group, Guohua Energy Investment.
It is near Dongying.
See below for data.
As a rule, economic wind generators require a wind speed of 4.5 m/s (16 km/h) or bigger.
An ideal position for a project like Dongying Hekou might have a near constant flow of non-turbulent wind all year round, having a minimum probability of sudden powerful bursts of wind. An important factor of turbine siting is furthermore admission to local requirement or transmission capaDongying.
During the planning stages the Dongying Hekou wind farm would’ve been checked and endorsed through wind measurements. However, Dongying Hekou wind farm would have needed more than simply meteorological data and measurements.
Site info around Dongying is a major element in the development decision Winds around Dongying are analysed for over a year or so plus the introduction of detailed maps. Only then are wind turbines installed.
The wind blows more quickly at higher altitudes as a result of reduced effect of drag. The rise in velocity with altitude is most remarkable near the surface and is affected by topography, surface roughness, and upwind obstructions such as trees or buildings. Velocity rises with altitude and it is more pronounced near land and is altered by topography, surface and limitations.
Wind speeds raising with altitude is part of a wind energy law. This Shandongs wind speed rises with the 7th root of altitude. Increasing the elevation of a turbine, then, increases the expected wind speeds by 10%, and the expected power by 34%.
In general, a range of 7D (7 × Rotor Diameter of the Wind Turbine) is set between each turbine in a fully developed wind farm. But this may not be the case in hilly areas.
Individual turbines at Dongying Hekou are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, it medium-voltage electric energy is increased in voltage using 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 roads to each and every turbine site.
