2. IEC 61400 - Wikipedia

   en.wikipedia.org/wiki/IEC_61400

   Considerable co-operation has been taking place between UK, USA, and more recently Japan, Denmark and other countries so that the IEC 61400-2 standard as interpreted within e.g. the MCS certification scheme (of UK origin) is interoperable with the USA (for example where it corresponds to an AWEA small wind turbine standard) and other countries.

3. Wind profile power law - Wikipedia

   en.wikipedia.org/wiki/Wind_profile_power_law

   The power law is often used in wind power assessments [4] [5] where wind speeds at the height of a turbine ( 50 metres) must be estimated from near surface wind observations (~10 metres), or where wind speed data at various heights must be adjusted to a standard height [6] prior to use. Wind profiles are generated and used in a number of ...

4. Wind turbine - Wikipedia

   en.wikipedia.org/wiki/Wind_turbine

   Offshore wind turbines are built up to 8 MW today and have a blade length up to 80 meters (260 ft). Designs with 10 to 12 MW were in preparation in 2018, [45] and a "15 MW+" prototype with three 118-metre (387 ft) blades is planned to be constructed in 2022. [needs update] [46] The average hub height of horizontal axis wind turbines is 90 ...

5. Wind resource assessment - Wikipedia

   en.wikipedia.org/wiki/Wind_resource_assessment

   Vertical shear to extrapolate measured wind speeds to turbine hub height: The hub heights of modern wind turbines are usually 80 m or greater, but developers are often reluctant to install towers taller than 60m due to the need for FAA permitting in the US, and costs. The power law and log law vertical shear profiles are the most common methods ...

7. New turbine design proposes to capture more of Tehachapi's wind

   www.aol.com/turbine-design-proposes-capture-more...

   Wind Harvest says recent modeling suggests that by capturing wind 15 to 100 feet above the ground, instead of hundreds, it may be able to nearly triple the power output of the Tehachapi Wind ...

8. Enercon E-126 - Wikipedia

   en.wikipedia.org/wiki/Enercon_E-126

   Enercon E-126 wind turbine. The Enercon E-126 [1] is an onshore [2] [3] wind turbine model manufactured by the German company Enercon.With a hub height of 135 m (443 ft), rotor diameter of 126 m (413 ft) and a total height of 198 m (650 ft), the turbine can generate up to 7.58 megawatts of power, making it the largest wind turbine in the world (by nameplate capacity) for several years, until ...

9. Roughness length - Wikipedia

   en.wikipedia.org/wiki/Roughness_length

   In wind vertical profile such the log wind profile, the roughness length (with dimension of length and SI unit of metres) is equivalent to the height at which the wind speed theoretically becomes zero in the absence of wind-slowing obstacles and under neutral conditions. In reality, the wind at this height no longer follows a logarithm.
