Disclosed are a regulation method and a regulation device for a converter of a wind turbine generator in a wind power plant. The regulation method comprises: acquiring real-time voltage and current signals of a grid connection point (); acquiring real-time state information of each wind turbine generator on the same electrical circuit in a wind power plant (); and generating a unified regulation instruction on the basis of the acquired real-time voltage and current signals and the acquired real-time state information (). The real-time state information comprises the total number of three-phase bridge arms of converters of currently running wind turbine generators on the same electrical circuit in the wind power plant, serial numbers that are dynamically allocated for the converters of the currently running wind turbine generators and their respective three-phase bridge arms, and the real-time power of each currently running wind turbine generator. The unified regulation instruction comprises a regulation instruction for the converter of each currently running wind turbine generator, wherein the regulation instruction comprises a phase shift angle reference value of a carrier, a carrier ratio reference value, and a characteristic quantity reference value of a modulated wave, which are required for the regulation of each three-phase bridge arm in the converter.
