On The Theory of SODAR Measurement Techniques Report

There are many things regarding intensity, signal, comparison, spectrum, wind, error, the turbulence intensity, measurements, and measurement are explained in this report. Inside the report the reader can read things around resolution, speed measurements, volume measurements, sodar, errors, range, turbulence, and wind speed measurements.

This report presents info around speeds, direction, anemometer, turbulence intensity, frequency, anemometers, wind speeds, and power. The following are chosen from this report:

The cost and the technical difficulties for performing wind speed measurements has also increased with the size of the wind turbines, since it is demanded that the wind speed has to be measured at the rotor center of the turbine and the size of both the rotor and the hub height have grown following the increase in the size of the wind turbines. 36 Risø-R-1410(EN) Figure 22 Lifting (tangential) force along a rotor blade (left: stall regulated wind turbine, right: pitch regulated wind turbine) (From: Hau 2002) Figure 23 Overestimation of wind speed (left) and available wind energy (right) as a function of hub height and rotor diameter in % when using point measurement of wind speed at hub height instead of using a wind profile measurement by SODAR. Risø-R-1410(EN) 37 Figure 24 Vertical profiles of mean wind speed and available wind energy 5.2.2 Consequences due to the wind speed difference between the lower and the upper rotor part The knowledge of the wind speed all over th

Even more, this report explains information regarding parameters, background noise, sodar measurements, rise time, the wind speed, speed, wind speed, and pulse.
