<p>Gas turbine and method for controlling an operating point of the gas turbine that includes a compressor, a combustor and at least a turbine. The method includes calculating an exhaust temperature reference curve of the turbine as a function of a turbine pressure ratio; determining whether condition IGV<sub>min</sub> + Î IGV1 â ¤ IGV<sub>set point </sub>â ¤ IGV<sub>max</sub> + Î IGV<sub>2</sub>, and condition ttx â ¥ ttxh + Î ttx<sub>3</sub>, are true; and changing, if both conditions are true, a split fuel quantity from a first value to a second value or otherwise maintaining the first value, the first value characterizing a lean-lean steady state mode and the second value characterizing a premixed secondary mode of a premixed mode.</p> |
