Asahi II wind farm is located in Chiba, Japan. It was in fact brought online in 2006 and is owned by .
It is near Asahi City.
See below for data.
Wind farms, as a general rule require wind speeds of 4.5 metres per second or more.
An ideal place for a project like Asahi II might have a near constant flow of non-turbulent wind all year long, with a minimum chance of sudden powerful bursts of wind. An important factor of turbine siting is furthermore admittance to local demand or transmission capaAsahi City.
During the planning stages the Asahi II wind farm would have been checked and endorsed through wind measurements. Meteorological wind data alone is usually not enough for precise siting of a large wind power project.
Assortment of site-specific data for wind speed and direction might have been essential to determining site potential to be able to finance the project. Winds around Asahi City are examined for at least a year or so plus the introduction of detailed maps. Only then are wind turbines installed.
The wind hits more rapidly at greater altitudes as a result of reduced influence of drag. The increase in velocity with altitude is most dramatic at the surface and is impacted by topography, surface roughness, and upwind limitations such as trees or buildings. Velocity rises with altitude and it is more obvious near land and is altered by geography, surface and obstructions.
Wind speeds escalating with altitude is part of a wind energy law. This forecasts wind speed rises with the 7th root of altitude. Doubling the altitude of a turbine, then, enhances the expected wind speeds by 10%, and the estimated power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out so that they don’t affect each other. But micrositing maximizes placement, particularly in hilly areas.
Individual turbines at Asahi II are interlocked with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, that medium-voltage electric current is improved in voltage with a transformer for connection to the high voltage transmission system. Building of a land-based wind farm requires installation of the collector system and substation, and perhaps roads to each turbine site.
