WebGiven the discussion above about the importance of accurate wind speed measurements, it is clear that it will be important to measure the wind speed as near to the hub height of the proposed turbine as possible. If a hub height measurement is not made then it will be necessary to estimate the shear profile. Because wind is an element that varies rapidly over very short periods of time it is sampled at high frequency (every 0.25 sec) to capture the intensity of gusts, or short-lived peaks in speed, which inflict greatest damage in storms. The gust speed and direction are defined by the maximum three … Meer weergeven Wind speed is normally measured by a cup anemometer consisting of three or four cups, conical or hemispherical in shape, … Meer weergeven Where wind measurements are made in extreme weather conditions, such as on the top of mountains, a heated sonic anemometer is used having no moving parts.
