Harmonic suppression method, system and equipment for power distribution network

The invention discloses a power distribution network harmonic suppression method, system and equipment, and relates to the technical field of power distribution network harmonic suppression, and the method comprises the steps: obtaining the harmonic compensation current magnitude of a power grid and the harmonic data of a plurality of low-voltage users, carrying out the classification processing of each harmonic data, obtaining a plurality of evaluation index sets, carrying out the fixed weight processing of each evaluation index set, and obtaining a plurality of low-voltage users; the method comprises the steps of obtaining a judgment weight coefficient corresponding to each judgment index set, constructing a judgment index vector of each judgment index set according to a data type of each judgment index set, and performing compensation distribution on the power grid harmonic compensation current magnitude by adopting each judgment weight coefficient and each judgment index vector to obtain a compensation ha
