Principle Of Operation 

 

Generator 

 
The 3 phase ac generator is driven directly by the aerofoil blades, rotating 
permanent magnets around the fixed stator winding.  The variable frequency 
alternating current is rectified within the generator housing, and the resulting 
rectified current is transmitted via the sliprings and brushes at the yaw axis to 
the output cable. 
 

Winding Over-Temperature Protection 

 
The generator stator winding incorporates embedded thermal protection to 
protect the winding from damage due to over temperature during extreme winds. 
On reaching the thermal protection limit, the device will reduce generator output 
current to allow the winding to cool, whereupon normal performance will be 
resumed.  If the thermal protection is active, the turbine may reduce to a slow 
rotational speed with a corresponding reduction in charge current, this is normal. 
 

Furling Tail System

 

 

The tail assembly is designed to direct the turbine into the main direction of the 
wind at windspeeds up to approx 15m/s.  Above this the automatic “furling” 
mechanism is activated to turn the generator at an angle to the wind to protect 
the turbine, generator and supporting structure from severe electrical and 
mechanical loads due to high winds.  When the wind speed subsides, the tail 
assembly will automatically return the turbine to normal operation.  In prolonged 
gusty & turbulent conditions, the system may be seen to repeat this cycle many 
times.  Power will be reduced during furling.  For effective operation of the furling 
system the wind turbine must be sited to ensure it is as free as possible from 
turbulence and in a stable upright position.
