Dongtai Phase II expansion wind project was set up in Jiangsu, China It was in fact brought online in 2013 and is owned by Guohua Energy Investment.
It is near Dongtai.
See below for data.
As a general rule, economic wind generators require a wind speed of 4.5 m/s (16 km/h) or greater.
A perfect destination for a project like Dongtai Phase II expansion might have a near constant flow of non-turbulent wind year round, having a minimum probability of abrupt powerful bursts of wind. An important factor of turbine siting is also admittance to local requirement or transmission capaDongtai.
Before development, Dongtai Phase II expansion was most likely screened on the foundation of a wind atlas, and validated with wind measurements. However, Dongtai Phase II expansion wind farm might have needed more than just meteorological data and measurements.
Assortment of site-specific data for wind speed and direction might have been imperative to determining site potential to be able to finance the project. Winds around Dongtai are analysed for over a year or so plus the introduction of detailed maps. Only then are wind turbines installed.
The wind hits speedier at greater altitudes due to the reduced effect of drag. The increase in velocity with altitude is most remarkable near the surface and is impacted by landscape, surface roughness, and upwind limitations such as trees or buildings. Velocity boosts with altitude and it is more evident near land and is transformed by terrain, surface and limitations.
Commonly, the growth of wind speeds with escalating elevation follows a wind profile power law, which anticipates that wind speed rises proportionately to the seventh root of altitude. Increasing the height of a turbine, then, boosts the anticipated wind speeds by 10%, and the expected power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they are spaced out in order that they don’t affect each other. But this isn’t necessarily the case in hilly areas.
Individual turbines at Dongtai Phase II expansion 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 improved in voltage with a transformer for link with the high voltage transmission system. Development of a land-based wind farm requires setting up the collector system and substation, and perhaps roads to each and every turbine site.
