BCAS Wind
The Bird Collision Avoidance System for wind farms is a fully automated detection and deterrence solution for on- and off-shore wind turbine generators. With detection distance of up to 1000 meters and targeted deterrence capabilities at 400 meters, it minimizes WTG stoppages providing uninterrupted operation and green power generation. The system operates without the need for human operator, 24/7 in all weather conditions.
The BCAS Wind Technology
Detection
Panoramic Thermal Imaging Camera
- Two BCAS Wind units on each wind turbine tower provide 360° coverage
- Up to 1000 m detection
- Detection, recognition, and tracking of birds in all weather conditions, even in zero-visibility
- Multiple bird detections
Deterrence
Acoustic Module
- Designed to evoke ASR (Acoustic Startle Reflex)
- Powerful acoustic emitter – 145 dB @ 1 m
- Effective deterrence at 400 m
- Unique sound wave – no habituation, no harassment ● Minimal noise disturbance – only upon detection
- Sound wave focused at targeted birds
Data
Monitoring and Control Center
- Modular web-based application
- Video record of every detection
- Remote control of all functions
- Quick storage and data retrieval
- Statistical database with detection logs
- Graphical display of data analyses
- WTGC modules for generator shutdown if needed
