Beschreibung
Zusammenfassung:	A method for operating a gas turbine plant with gaseous fuel, which is conveyed to the gas turbine plant through a gas line, burnt in a combustion chamber and then supplied to a gas turbine. At least one valve for controlling the flow of the fuel to the combustion chamber is installed in the gas line, a critical opening position being defined for the valve. To provide an improved method for operating a gas turbine plant in which the power of the gas turbine plant is kept at a maximum for as long as possible in the event of insufficient pressure in the gas line, a temperature of the fuel in the gas line is reduced when the valve is about to exceed the critical opening position.
