    摘要： A method (300) for determining fuel splits includes monitoring (302) an airflow-related parameter of a gas turbine (100) and determining (304) first (212) and second reference values (214) for the airflow-related parameter based on a combustion reference temperature (CRT). The first reference value (212) is associated with a first load path (10) of the gas turbine (100) and the second reference value (214) is associated with a second load path (12) of the gas turbine (100). The method (300) also includes determining (310) first (252) and second fuel split commands (254) based on the combustion reference temperature (CRT). In addition, the method (300) includes determining a fuel split value (260) to be applied in association with a monitored value of the airflow-related parameter based at least in part on the reference values (212, 214) and the fuel split commands (252, 254) and applying the fuel split value (260) to regulate an amount of fuel supplied to one or more fuel circuits of the gas turbine (100).
