摘要

Abstract

The fractional frequency transmission system is an emerging technology for long-distance wind power integration

and the modular multilevel matrix converter (M3C) is the keen equipment. Since the M3C directly connects two ac grids with different frequencies

the external and internal harmonics have complex coupling relationships with a unique dual-fundamental-frequency spectrum

which has not been properly investigated due to a lack of an effective method. To address this issue

a novel harmonic state-space method is proposed to achieve comprehensive modelling of the harmonic dynamics of the M3C. Based on the principle of two-dimensional Fourier transform

the decomposition of the dual-fundamental-frequency harmonics is realized

and the multiplicative coupling between time-domain variables is modelled through double-layer convolution on the frequency domain. Besides

the general expression of the proposed method is provided

which highlights a modularized matrix with easy scalability to meet different truncation requirements. Then

the HSS model of M3C considering the close-loop control is established

based on which a panoramic harmonic coupling relationship between the system- and the low-frequency side is concluded. Finally

the M3C model and harmonic coupling relationship are validated by simulation tests conducted in MATLAB/Simulink environment.
