WT-BIRD BIRD COLLISION MONITORING SYSTEM FOR
MMW-WIND TURBINES
- Edwin Wiggelinkhuizen, ECN Wind Energy

The problem with bird collisions
- Hampers planning process and permits
- Bad examples harm reputation of wind energy
- Available collision monitoring methods are
- labor intensive
- not very accurate
- not applicable on large scale or offshore
- Urgent need for data to validate collision risk
models - WT-Bird specifications, development and field
test results

WT-Bird main specifications
- Continuously detect and count collisions
- Store video registrations (sufficient quality,
remote access to minimise analysis effort) - Simple installation with minor turbine
modifications - Maintenance interval of 1 year at least
- Calibrated for each configuration and type of
turbine
Acknowledgement WT-Bird development program has
been financially supported by SenterNovem (NL)

WT-Bird the system
- Detection
- acoustic sensors in blades
- real-time signal processing
- Registration
- cameras and IR-lights at tower
2.5MW, 80m tower

WT-Bird Future developments
- Verification together with ornithologists
- Design improvements
- optimize configuration at wind farm scale
- apply improved video equipment
- Application on different turbine designs
- tune triggering
- meet installation requirements
ECN is ready for large-scale implementation!
