Abstract:
An important implementation issue for wind farms is the risk of birdcollision. A lot of the existing knowledge on birds and wind energy
is based on studies at onshore sites. With respect to wind energy implementation
especially offshore, more information about the environmental impact
is needed. Several countries carrying out environmental base line studies
focused on offshore wind farm sites. Monitoring wildlife is very labour
intensive. That's why ECN develops a computer based efficient environmental
monitoring tool.
The aim is to develop, demonstrate and evaluate a noise monitoring system,
which identifies bird impacts and also indicates the species. The system
must be relatively inexpensive, robust and applicable for offshore conditions.
The system identifies bird impacts by noise measurements and a camera
identifies the specific species. The system can also distinguish between
turbine specific sounds and a real collision agains tower, nacelle and
rotor.
The WT-Bird detection system built by ECN appears to be a very promising
way to detect bird collisions against wind turbines. The first experimental
results are good. This way of detecting the collisions of birds can
be very useful for the future implementation of offshore wind farms.
