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
