PROBLEM TO BE SOLVED: To provide a method of managing transient events regularly seen during gas turbine operation that may cause undesirable operation and hardware damage. SOLUTION: 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 a 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. Combustion dynamics are known to cause damage that may require hardware replacement. Once the transient has completed, normal control operation is resumed. COPYRIGHT: (C)2009,JPO&INPIT |
