Claim 0:
1. A method for regulating converters of wind turbines in a wind farm, comprising:
obtaining real-time voltage and current signals at a point of common coupling;
obtaining real-time status information of wind turbines on a same collecting line in the wind farm; and
generating a unified regulation instruction based on the real-time voltage and current signals and the real-time status information as obtained,
wherein the real-time status information comprises: a total number of three-phase bridge arms of converters of currently running wind turbines on the same collecting line in the wind farm, serial numbers dynamically assigned to the converters of the currently running wind turbines and the three-phase bridge arms of the converters, and a real-time power of each of the currently running wind turbines, and
wherein the unified regulation instruction comprises regulation instructions for all the converters of the currently running wind turbines, and each of the regulation instructions comprises a reference value of a phase shift angle and a reference value of a carrier ratio of a carrier, and a reference value of a characteristic quantity of a modulated wave, for regulation of each of three-phase bridge arms in a respective converter.
