摘要： A method of controlling operability of a gas turbine during part-speed operation includes identifying that a combustion system of the gas turbine is operating at part-speed, the combustion system including a fuel source, fuel circuits and valves operably interposed between the fuel source and the fuel circuits, respectively, defining first and second boundaries based on first and second parameters and automatically controlling each of the valves to control fuel flow to each of the fuel circuits in accordance with the defined first and second boundaries.
