Mechanical vibration. Torsional vibration of rotating machinery - Land-based steam and gas turbine generator sets in excess of 50 MW1 Scope This part of ISO 22266 provides guidelines for applying shaft torsional vibration criteria, under normal operating conditions, for the coupled shaft system and long blades of a turbine generator set. In particular, these apply to the torsional natural frequencies of the coupled shaft system at line and twice line frequencies of the electrical network to which the turbine generator set is connected. In the event that torsional natural
