The paper presents a modulation and iterative harmonic analysis method, which can be used for modeling the multi-harmonic sources in AC/DC hybrid transmission system. Based on the detailed nonlinear mathematical model the fast and separate calculation of harmonics in AC and DC networks can be implemented, and the generation mechanism of harmonics and interaction process of harmonics in AC and DC networks is analyzed. The fact that harmonic analytical calculation accord with the detailed digital simulation proves the proposed modeling method is valid
