Ajigasawa I wind project was set up in Aomori, Japan It was brought online in 2003 and is owned by .
It is near Ajigasawa Town.
See below for data.
Typically, economic wind power generators require a wind speed of 4.5 m/s (16 km/h) or more.
An ideal place for a project like Ajigasawa I could have a near constant flow of non-turbulent wind year round, having a minimum probability of abrupt powerful bursts of wind. Additionally, you wouldn’t get a turbine like associated if Ajigasawa I was not built near local demand or transmission capaAjigasawa Town.
During the planning stages the Ajigasawa I wind farm would’ve been checked and endorsed through wind measurements. Meteorological wind data alone is usually not adequate for exact siting of a large wind power project.
Collection of site-specific data for wind speed and direction could have been crucial to determining site potential as a way to finance the project. Winds around Ajigasawa Town 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 higher altitudes due to the reduced effect of drag. The surge in velocity with altitude is most extraordinary at the surface and is impacted by geography, surface roughness, and upwind hurdles such as trees or buildings. Velocity rises with altitude and is more obvious near land and is changed by landscape, surface and obstacles.
Generally, the increase of wind speeds with raising elevation follows a wind profile power law, which forecasts that wind speed rises proportionately to the seventh root of altitude. Increasing the altitude of a turbine, then, raises the expected wind speeds by 10%, and the predicted power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out so they don’t affect each other. However this isn’t necessarily the way it is in hilly areas.
Individual turbines at Ajigasawa I are connected with a medium voltage (usually 34.5 kV) power collection system and communications network.
At a substation, that medium-voltage electric energy is enhanced in voltage using a transformer for connection to the high voltage transmission system. Development of a land-based wind farm requires setting up the collector system and substation, and perhaps access roads to every turbine site.
