Dachen Island Phase I wind project was installed in Zhejiang, China It was in fact brought online in 2009 and is owned by .
It is near Taizhou.
See below for data.
Wind farms, as a general rule require wind speeds of 4.5 metres per second or more.
The best destination for a project like Dachen Island Phase I might have a near constant flow of non-turbulent wind year round, having a minimum chances of abrupt powerful bursts of wind. Additionally, you would not get a turbine like involved if Dachen Island Phase I was not built near local demand or transmission capaTaizhou.
During the planning stages the Dachen Island Phase I wind farm would’ve been checked and confirmed through wind measurements. Meteorological wind data alone is usually not ample for precise siting of a large wind power project.
Site data around Taizhou is a major factor in the ‘development’ conclusion Winds around Taizhou are evaluated for over a year or so alongside the creation of detailed maps. Only then are wind turbines installed.
The wind hits more quickly at higher altitudes as a result of reduced effect of drag. The surge in velocity with altitude is most dramatic close to the surface and is affected by topography, surface roughness, and upwind obstructions such as trees or buildings. Velocity rises with altitude and is also more evident near land and is altered by terrain, surface and hurdles.
Wind speeds increasing with altitude is part of a wind energy law. This Zhejiangs wind speed rises with the 7th root of altitude. Increasing the height of a turbine, then, enhances the expected 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 micrositing increases placement, particularly in hilly areas.
Individual turbines at Dachen Island Phase I are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, that medium-voltage electric current is enhanced in voltage using 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 possibly access roads to each turbine site.
