摘要：The presence of sub-synchronous torques on the rotor causes concern because the turbine-generator shaft itself has natural modes of oscillation that are typical of any spring mass system. It happens that the shaft oscillatory modes are at sub-synchronous frequencies. Sub-synchronous resonance can cause shaft fatigue and possible damage or failure. To improve system security, sub-synchronous resonance must be controlled. In this paper, modeling and analysis are established of Multi-Mass Turbine-Generator (MMTG) simulator in laboratory. Resonance frequency of MMTG simulator is analyzed by simulation and by experiment using impulse test
