摘要

•A wide-area monitoring and early-warning system of SSO is proposed.•The system incorporates locally deployed S-PMUs and a centralized DC&SDA.•A global view of SSO is established with the subsynchronous state estimation.•The subsynchronous power & current flow is formed to locate oscillation source/path.•Two stability criteria are used for the real-time evaluation of SSO stability.
