Claim 3:
4. The method according to claim 3, wherein the step of calculating the reference value of the phase shift angle of the carrier for regulation of each of the three-phase bridge arms in the converters of each currently running wind turbine comprises:
calculating the reference value of the phase shift angle of the carrier based on the following formula:, θ
