摘要： A method of controlling an operating temperature of a first combustion zone of a combustor of a rotary machine includes determining a current operating temperature and a target operating temperature of a first combustion zone using a digital simulation. The method further includes determining a derivative of the current operating temperature with respect to a current fuel split using the digital simulation. The fuel split apportions a total flow of fuel to the combustor between the first combustion zone and a second combustion zone. The method also includes calculating a calculated fuel split that results in a calculated operating temperature approaching the target operating temperature. The method further includes channeling a first flow of fuel to the first combustion zone and a second flow of fuel to the second combustion zone.

摘要： Methods and systems for detecting an oscillatory event are provided. According to one embodiment, a system may include a controller configured to provide a command signal to a positioning device and a processor communicatively coupled to the controller. The command signal may include a reference position. The processor may be configured to monitor a feedback signal responsive to the command signal. The feedback signal may include an actual position of the positioning device. The processor may be further configured to determine that within a predetermined period of time the actual position is both above a predetermined upper threshold and below a predetermined lower threshold. Based on the determination, the processor may declare the oscillatory event.
