Beschreibung
Zusammenfassung:	The invention relates to the technical field of alternating-current and direct-current power transmission, in particular to a CLCC harmonic suppression method based on a switching function, which comprises the following steps: S1, establishing a CLCC switching function model, and representing the transformation relation of CLCC alternating-current and direct-current side voltage and current through the switching function model; s2, harmonic transmission from the alternating current side to the direct current side of the CLCC and harmonic transmission from the direct current side to the alternating current side of the CLCC are analyzed; s3, during operation of the CLCC, a direct current filter is additionally arranged on the direct current side, and generation and propagation of harmonic waves on the direct current side are inhibited; and S4, if the non-characteristic harmonics exist on the alternating current side, adding an alternating current filter on the alternating current side, and inhibiting generation
