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

A method for mitigating undesired gas turbine transient response using event-based actions wherein a difference between a measured reference exhaust temperature and an actual turbine exhaust temperature may result in at least one of combustion dynamics or loss of flame;

• the method comprising:
• sensing input data for gas turbine operational parameters;
• determining which event from a set of predetermined transient events included in Table I has occurred based on the sensed operational parameters;
• and
• initiating a predetermined priority of response for the predetermined transient event.

A gas turbine comprising:

• a compressor;
• a combustor;
• a turbine;
• sensors providing data for gas turbine operational parameters;
• a fuel control system, including fuel split schedules according to operational parameters;
• and
• a controller including:
• sensor inputs including data for gas turbine operational parameters;
• a processor executing a program, wherein the program includes a set of predetermined gas turbine transient events, including at least one transient event listed in Table I wherein a difference between a measured reference exhaust temperature and an actual turbine exhaust temperature may result in at least one of combustion dynamics or loss of flame;
• a function of recognition of the transient events from the gas turbine operational parameters based on the sensor inputs, and
• a programmed response to mitigate the effects of the gas turbine transient events on the combustion dynamics or the loss of flame.
