This part of ISO 22266 provides guidelines for applying shaft torsional vibration criteria, under normaloperating 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 frequenciesof the electrical network to which the turbine generator set is connected. In the event that torsional naturalfrequencies do not conform with defined frequency margins, other possible actions available to vendors aredefined.This part of ISO 22266 is applicable to? land-based steam turbine generator sets for power stations with power outputs greater than 50 MW andnormal operating speeds of 1 500 r/min, 1 800 r/min, 3 000 r/min and 3 600 r/min, and? land-based gas turbine generator sets for power stations with power outputs greater than 50 MW andnormal operating speeds of 3 000 r/min and 3 600 r/min.Methods currently available for carrying out both analytical assessments and test validation of the shaftsystem torsional natural frequencies are also described.
