Abstract:
1. A controller in a gas turbine having a compressor, a combustor and a turbine with a fuel split schedule, the controller comprising: sensor inputs receiving data for gas turbine operational parameters; a fuel control system including fuel splits according to the 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.
