Abstract:The safety and stability of power systems is seriously threatened by subsynchronous oscillation (SSO) caused by integration of large-scale wind power. Due to the widespread adoption of power electronic devices, the mechanism and mode of the new type of SSO involving wind power are different from those of traditional SSO. Particularly, the SSO in doubly-fed induction generator (DFIG) based wind farms and direct-drive permanent magnet synchronous generator (PMSG) based wind farms have attracted extensive attention and research both at home and abroad. The commonly used analysis methods and their applicability were summarized. Then, the theoretical results and engineering practices in the aspects of analysis, control and protection of wind power SSOs in recent years were summarized based on typical engineering incidents. The paper aims to provides a reference for the future study of wind power SSO.
