DOUBLE CONVERTER FOR WIND GENERATORS WITH
VARIABLE SPEED AND SYNCHRONOUS GENERATION
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.
