DTBird Successfully Tests its V4D4 Module in the United States

0
DTBird’s ability to detect and deter large raptors, particularly golden eagles, and to reduce the risk of collisions with wind turbines (WTG) was evaluated in the US by H.T. Harvey & Associates for the American Wind Wildlife Institute.

One of the unmanned aerial vehicles used in the tests

The evaluation was carried out in seven DTBirdV4D4 units installed in 2016 in a California wind farm, using eagle-like unmanned aerial vehicles (aka, UAV) with a 2 m wingspan, and studying in situ large raptor behavior registered during 2017.

 

 

 

 

 

From the evaluation, DTBird has calculated  and extracted the following major results:

    • DTBirdV4 Detection Module:
      •  Up to 99% over all eagle-like UAV Detection rate from > 230 m to the Rotor Swept Area (RSA). Calculated by DTBird Team.
      •  63% mean detection rate per distance band of 30 m (7 distance bands from >230 m to the RSA). Extracted from the report.
      • 2.5 false positive rate (flight recording of something other than birds)/WTG/day. Calculated by DTBird Team.
    •  DTBirdD4 Collision Avoidance Module:
      • Deterrence response rates when considering unequivocally successful deterrence and potential deterrence:
        • 52-83% for golden eagles.
        • 36-76% for buteos.
        • 39-78% for all raptors. 
    • DTBirdV4D4 service reliability(operation without failures) calculated by DTBird Team:
      • >98% System.
      • >98% HD Cameras.
      • 100% Collision Avoidance Module.
