Characterization + Classification of the Class 1 Anemometer for IEC 61400‐12‐1 Compliance

This white paper documents the results and supporting work to characterize and classify the Class 1 Anemometer according to the guidelines documented in the DTU Wind Energy Department’s Accuwind reports and the IEC 61400‐12‐1 Standard.

Developing an Ultrasonic Acoustic Bat Deterrent System for the Wind Industry

Wind turbines have been shown to cause direct mortality to bat species, with bat deaths documented at wind energy facilities around the world. Building upon insights from nature and a great deal of previous research, NRG Systems developed its Bat Deterrent System to mitigate the wind industry's impact on bats. This white paper provides an overview of the development of this pioneering solution.

Post Calibrating the 40C Anemometer in the SOH Wind Engineering (SOH WE) Wind Tunnel

Two procedures – one simplified, one rigorous – are provided in this white paper, defining the process of evaluating SOH WE post-calibrations of 40C Anemometers initially calibrated at Otech.

Power Performance Testing with Stand-Alone WINDCUBE® Lidar

It is well known that the IEC ‐12‐1:2005 methodology requires the use of a hub height meteorological mast to measure the wind conditions upwind of the turbine(s) being tested. In this white paper, it is argued that ground‐based WINDCUBE Lidar technology provides a very similar input for assessing wind turbine performance in simple terrain sites, mimicking the role of an IEC met mast but with a much higher degree of flexibility and at a much lower cost.

Summary of Cup Anemometer Classification - WindSensor P2546A-OPR + P2546C-OPR

Danish Technical University (DTU) Wind Energy Department has classified the WindSensor P2546A-OPR anemometer in compliance with the procedures outlined in IEC 61400-12-1:2005 Annex I.
