CHARACTERISTICS

-IGBT's technique 

 
-Variable rotor speed in a wide range in order to increase the captured energy with low and medium wind speed.

 
-Generation of Active Power with Unit Power Factor.

 
-Possibility to couple the Wind Generator to weak grids.

-Possibility of injection of Reactive Energy for grid balance.

 
-Soft and progressive control of the slopes for Power capturing.

-Lower mechanical stress due to Wind gusts.

 
-Eliminates Start Up by means of thyristors, the control Rack and the Reactive Compensation. By being coupled to multipole synchronous generators eliminates the speed gear box.
