The annual energy production of individual wind turbines in complex terrain varies more than 30 %

[Data from BWE yearbook 2018]

Especially in complex terrain steep slope sides, differences in roughness length or tunnel effects create wind phenomena that lead to energy yield differences of more than 30 % for individual wind turbines within a single wind farm. The airborne wind measurement system WindLocator, developed at the Center for Wind Power Drives, enables autonomous, position-controlled measurement of local wind situations and thus yield-optimized park planning.

WindLocator - airborne wind measurement system

Wind speed | Wind direction | Turbulence intensity

  • High-accuracy 3D ultrasonic anemometer

  • Evaluation unit for compensation of relevant motion and rotor influences by means of sensor fusion

  • Operational for wind speeds up to 25 m/s

  • Fast and efficient deployment compared to established systems (met mast, LIDAR and CFD)
