Simple mass-spring model is often used as the model of complex turbine-generator shaft when simulating subsynchronous oscillation (SSO). However, this model cannot precisely describe torsional vibration characteristics of turbine-generator shaft. For estimating the effect of shaft model on subsynchronous oscillation, simple mass-spring model of uncertain parameters was used in this paper. The AC-DC...
The An-Bao line low frequency oscillation occurred in Hebei province power grid of China was analyzed in this paper. The oscillation modes of Hebei power grid were obtained by eigenvalue analysis. The An-Bao line oscillation frequency was obtained though applying Prony method to analyze field data. Simulation results indicate that the An-Bao line low frequency oscillation cannot be interpreted by...
