Open-loop mode resonance risk determination based on measurement model

电力工程技术
The open-loop mode resonance theory is an important theoretical achievement to explain the mechanism of system instability caused by the grid connection of permanent magnet synchronous generator (PMSG), but the determination of the resonance risk of open-
