This part of ISO22266 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 frequencies do not conform with defined frequency margins, other possible actions available to vendors are defined.
This part of ISO22266 is applicable to
-
land-based steam turbine generator sets for power stations with power outputs greater than 50MW and normal operating speeds of 1500r/min, 1800r/min, 3000r/min and 3600r/min, and
-
land-based gas turbine generator sets for power stations with power outputs greater than 50MW and normal operating speeds of 3000r/min and 3600r/min.
Methods currently available for carrying out both analytical assessments and test validation of the shaft system torsional natural frequencies are also described.
