TR6 (Rev. 11)
The technical guideline TR6, published by the German "Fördergesellschaft Windenergie und andere Erneuerbare Energien", describes processes to determine the wind potential and the energy yield at sites for wind turbines („Bestimmung des Windpotentials und Energieertrags an Standorten für Windkraftanlagen“). The guideline focuses on wind measurement considering wind met masts as well as SoDAR and LiDAR devices.
Under certain conditions, the guideline accepts wind speed and direction measurement exclusively with remote sensing systems.
The TR6 guideline also defines criteria for data quality. Thus measurement data has to be checked for integrity and plausibility on a regular basis. This guideline is mainly applied in Germany. more
