Online analysis and early-warning method of subsynchronous resonance based on time-domain simulation

Subsynchronous resonance risk assessment in power system is mainly accomplished by offline simulation analysis, for a practical project, researchers have to consider all kinds of possible typical system operation modes, which might be a huge amount for a large-scale transmission system. This paper comes up with subsynchronous resonance online monitoring, analyzing and early-warning technologies, applies time-domain simulation to adaption and process subsynchronous resonance online analysis, and develops an online analysis and early-warning system based on computer cluster.
