Lightning Safety Systems
6Stage Speed Control Design
Orenda Energy Solutions’ Skye™ wind turbine has a hierarchy of systems to control the turbine as wind-speed increases, and ultimately bring the turbine to a controlled stop:
1. Electrical Load Torque Control
2. Hydrostatic Braking (patent pending)
3. Stall Regulated Blades
4. Active Yaw
5. Emergency/Parking Brake
6. Dynamic Resistive Load (Grid loss)
System / Device Description
Nacelle The anemometer has integrated lightning protection
BladesThe blades have a copper cable from tip to base to channel lightningConforms to IEC 61400-2
Turbine Bearings
The turbine bearings are protected by 200kV insulation, the lightning charge is carried from the turbine shaft to the tower by dual 1,000 volt brushes
