Adapting wind turbines to bird behaviour

Norwegian researchers at SINTEF are currently working on a new concept – involving turbines that adapt to bird behaviour, rather than the other way around.

Official Press Release SINTEF:

Active control of wind turbine speed can lead to fewer bird strikes

Norwegian researchers are currently developing wind turbines that can adapt their blade rotation speeds to prevent bird strikes.

Sound signals, lights, painting the rotor blades, and rapid shutdowns have all been tried in an attempt to reduce bird mortality. But researchers Paula B. Garcia Rosa and John Olav Tande at SINTEF are currently working on a new concept – involving turbines that adapt to bird behaviour, rather than the other way around.  What happens when a bird approaches an ‘adaptable’ wind turbine? “As the bird approaches, it is identified using cameras and bird radar systems mounted on the turbine”, says Garcia Rosa. “This identification has to take place at least five seconds, or at a distance of at... ...
