ROMO Wind’s patented iSpin wind measurement technology has been installed on two of the Vestas V80 turbines in Energiekontor’s company-owned Thüle wind farm in Lower Saxonia, Germany, enabling wind measurement directly at the spinner.
The result of the measurements: both turbines were affected by yaw misalignment of 8 degrees, and after correction on average 3.2 percent more production could be achieved.
Now the wind farm operator plans to equip further turbines with the iSpin spinner anemometer:
“The iSpin system is very lucrative for us. At Thüle wind farm alone we expect to gain 20,000 Euros more revenue through better measurement data. The data of the turbine manufacturers is not sufficient for that”, says Carsten Schwarz, head of operations of company-owned wind farms at Energiekontor AG.
