摘要：
The subsynchronous oscillation (SSO) phenomenon may occur in a modular multilevel converter-based high-voltage dc (MMC-HVDC) transmission system for wind farm integration, which has already been observed in the real world. In this paper, the generation mechanism of the SSO phenomenon in the interconnected system is revealed by means of impedance-based analysis. On this base, from the HVDC converter control point of view, stabilization control methods are proposed to guarantee the stability of the interconnected system. Both frequency-domain analysis and time-domain simulations are carried out to validate the effectiveness of the proposed stabilization control methods.
