摘要：The harmonic transfer characteristics in the distribution network were analyzed from two aspects of harmonic current and harmonic voltage in this paper. The analysis results show that the harmonic current mainly flows into the upper system when the filter device is not input. The transmission coefficient is related to the transformer ratio when the harmonic current is injected into the upper system and transmitted from the low pressure side to the high pressure. The harmonic voltage of the higher-level power grid is mainly concentrated on the load equivalent impedance of the current-level power grid when passing through the distribution network. When the harmonic filter voltage of the upper-level power grid is mainly transmitted, the system is mainly concentrated on the system of the current-level power grid.
