Claim 8:
9. The method according to claim 7, wherein the step of regulating based on the regulation instruction comprises:
performing the following operations for each of the three-phase bridge arms of the converters of each currently running wind turbine:
determining a carrier and a modulated wave for modulation of an IGBT on each of the three-phase bridge arms, based on the reference value of the phase shift angle of the carrier, the reference value of the carrier ratio and the reference value of the characteristic quantity of the modulated wave;
generating a trigger pulse sequence for the IGBT on each of the three-phase bridge arms, based on the carrier and the modulated wave as determined for modulation of the IGBT on each of the three-phase bridge arms; and
modulating the IGBT on each of the three-phase bridge arms based on the generated trigger pulse sequence for the IGBT on each of the three-phase bridge arms.
