Online Fatigue Monitoring System for Steam Turbine Rotor in Power Plants Considering Sub-Synchronous Oscillation
Year: 2012
Type: article
Abstract: This paper presents a system developed for online fatigue monitoring for steam turbine rotor in power plants. The system converts the plant transients to temperature and thermal stress responses using the analytical models modified by FEM. The torsional vibration caused by the possible sub-synchronous oscillation (SSO) phenomenon in power networks has been analyzed. The fatigue damage caused by thermal stress and SSO is studied based on the stress analysis and fatigue cumulation. The fatigue usage factor is computed using the rainflow cycle counting algorithm. The method can provide useful information in support of the unit’s life cycle management and efficient.
