Abstract: Disclosed is a method of fast identifying the distribution rule of wind speed, for identifying an optimal distribution rule of known wind speeds, wherein transforming all types of distribution rules to be selected by Rosenblatt transformation to a uniform type based on the selected distribution type of the probability paper, and drawing the reference curve on the probability paper; selecting a plurality of distribution rules, selecting the known wind speed data as the sample data and comparing the point set of the sample data to the reference curve; judging the optimal distribution rule among the selected distribution rules according to the comparison result. The present invention is appropriate for identifying the distribution of wind speed of different range; the method is not specific to any probability paper that has wide applicability.
