Method of mitigating undesired gas turbine transient response using event based actions

A method of managing transient events regularly seen during gas turbine (10) operation that may cause undesirable operation and hardware damage. During certain transient operations, a lag may be seen between reference exhaust temperature and actual turbine exhaust temperature. This lag can result in...

Zusammenfassung:	A method of managing transient events regularly seen during gas turbine (10) operation that may cause undesirable operation and hardware damage. During certain transient operations, a lag may be seen between reference exhaust temperature and actual turbine exhaust temperature. This lag can result in an under-fired condition within the combustion system of variable magnitude and duration. Either fuel split schedules or a control algorithm can be positioned during these transients to prevent combustion dynamics or loss of flame. Once the transient has completed, normal control operation is resumed.
