摘要：

Modular multilevel converter control system link delay may cause high frequency resonance phenomenon. This paper establishes a mathematical model of high-frequency impedance for a modular multilevel converter including a link delay link, and studies the generation mechanism of high-frequency resonance of a modular multilevel converter based on impedance analysis. On this basis, a high-frequency resonance suppression strategy with a band-stop filter in the voltage feed-forward stage is proposed, and the control parameters of the band-stop filter are designed. Finally, the effectiveness of the proposed control strategy is verified by electromagnetic transient simulation. © 2021, Electrical Technology Press Co. Ltd. All right reserved.
