Amami wind project was set up in Kagoshima, Japan It was brought online in 2009 and is owned by .
It is near Amami City.
See below for data.
Wind farms, as a general rule need wind speeds of 4.5 metres per second or more.
An ideal place for a project like Amami might have a near constant flow of non-turbulent wind throughout the year, with a minimum probability of abrupt potent bursts of wind. Additionally, you wouldn’t get a turbine like associated if Amami was not built near local demand or transmission capaAmami City.
During the planning stages the Amami wind farm would have been checked and endorsed through wind measurements. Meteorological wind data alone is usually not enough for exact siting of a large wind power project.
Site data around Amami City would have been a major factor in the development final decision Winds around Amami City are analysed for over a year or so alongside the development of detailed maps. Only then are wind turbines installed.
Altitude would also possess a part to playin a project like Amami. This is due to drag The boost in velocity with altitude is most spectacular near the surface and is impacted by landscape, surface roughness, and upwind obstructions such as trees or buildings. Velocity boosts with altitude and is also more obvious near land and is altered by terrain, surface and limitations.
Sometimes, the growth of wind speeds with escalating height follows a wind profile power law, which anticipates that wind speed rises proportionately to the seventh root of altitude. Doubling the elevation of a turbine, then, raises the anticipated wind speeds by 10%, and the estimated power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they are spaced out to make sure they don’t affect one another. However this may not be the way it is in hilly areas.
Amami turbines are related via medium voltage lines and communications.
At a substation, this kind of medium-voltage electric energy is elevated in voltage with a transformer for connection to the high voltage transmission system. Development of a land-based wind farm requires installing of the collector system and substation, and possibly access roads to each turbine site.
