Zusammenfassung:The invention belongs to the technical field of wind power distribution, and provides a wind power distribution method and system, a medium and equipment. The method comprises the following steps: screening out an optimal state unit; decomposing the power sequence of the unit in the optimal state, and calculating the envelope entropy of a first mode obtained by decomposition; the envelope entropy of the first mode serves as a fitness function, and hyper-parameters of a variational mode decomposition algorithm are optimized; decomposing all wind turbine generator power sequences, and extracting modal features of each wind turbine generator power sequence; performing compression dimension reduction on the modal features of the power sequence of each wind turbine generator, and calculating the distance between the modal features of each wind turbine generator and the modal features of the optimal-state generator so as to obtain the relative health degree of each wind turbine generator; and when the wind power pl
