Safety Systems
• Induction generator has inherent antiislanding
• Centrifugally actuated blade-tip brakes
• Fail safe hydraulic disc brake
• Gearbox heating for cold weather
• Grid monitoring for fault shutdown inputs:
- Line voltage
- Line frequency
- Overproduction
• Over-speed monitoring on hub and generator for fault shutdown
• Thermal protection on generator
• Vibration sensor for fault shutdown
• Automatic cable untwist with emergency override for fault shutdown
• Thermal protection for pump and yaw motor circuits
• 90° nacelle yaw on fault events
• High wind speed fault shutdown
