Abstract: A method is disclosed for operating a gas turbine having a compressor, a combustor, a turbine downstream of the combustor, and a total number of turbine outlet temperature measurements. The method includes locally measuring the turbine outlet temperature of the turbine with the turbine outlet temperature measurements of the respective turbine, and averaging measured temperatures of the selected turbine outlet temperature measurements to obtain an average turbine outlet temperature. The gas turbine operation is controlled depending on the determined average turbine outlet temperature.

Abstract: The present disclosure refers to a method for operating a gas turbine having a compressor, a combustor, a turbine downstream of the combustor, and a total number of turbine outlet temperature measurement sensors. The method can include supplying a first fuel flow to one of the burners of one combustor, which is smaller than a second fuel flow to another one of the burners the same combustor, selecting a number of turbine outlet temperature measurements which is smaller than a total number of the turbine outlet temperature measurement sensors, and averaging measured temperatures of the selected turbine outlet temperature measurements to obtain an trimmed turbine outlet temperature which is used for controlling operation of the gas turbine.

Abstract: A method for operating a gas turbine plant is provided. According to the method a first fuel gas with a first fuel reactivity and a second fuel gas with a second fuel reactivity which is higher than the first fuel reactivity are injected into a combustor of the gas turbine, and the ratio of the mass flows of the second fuel gas to the first fuel gas is controlled depending on the combustion behavior of the combustor. A gas turbine plant configured to carry out the method is further shown.

Abstract: A plant with a fuel system includes a gas separation system for separating at least a first fuel fraction with high hydrocarbons, which has a higher concentration of high hydrocarbons than an incoming fuel gas. A second fuel fraction with a reduced concentration of high hydrocarbons is provided. A fuel gas supply line for incoming fuel and/or a fuel line for the second fuel fraction leads to the combustor of the gas turbine for feeding fuel gas into the combustor. Further a fuel line for feeding the first fuel fraction leads to the at least one combustor to control the combustion behaviour by controlled addition of the first fuel fraction into the combustor. The disclosure further refers to the operation of such a plant by controlling the combustion behaviour with the controlled addition of a high hydrocarbon fuel.
