System and method for compensating fuel composition variations in a gas turbine

Certain embodiments of the invention may include systems (100) and methods (200) for compensating fuel composition variations in a gas turbine (108). According to an example embodiment of the invention, a method (200) is provided for compensating for fuel composition variations in a turbine. The method can include: monitoring (202) at least one fuel parameter associated with a turbine combustor; monitoring one or more combustion dynamics characteristics associated with the turbine combustor; monitoring (204) one or more performance and emissions characteristics associated with the turbine; estimating (208) fuel composition based at least in part on the at least one fuel parameter, the one or more combustion dynamics characteristics, and the one or more performance and emissions characteristics, and adjusting (210) at least one fuel parameter based at least in part on the estimated fuel composition.
