Claim:
1. A method for controlling an operation of a gas supply system of a gas turbine, the method comprising: providing a gas supply and a first valve connected in series to a set of second valves placed in parallel with each other, wherein at least one second valve from the set of second valves is connected to a combustion chamber of the gas turbine; and changing a degree of opening of the first valve and the at least one second valve so as to control a total mass flow of gas output by the set of second valves, wherein changing the degree of opening of the first valve and the at least one second valve further comprises linearly decreasing the degree of opening of the first valve and linearly increasing the degree of opening of the at least one second valve during a first phase so as to reduce a pressure in a pipe located between the first valve and the set of second valves; wherein the degree of opening of the first valve is characterized by: linearly decreasing with time during the first phase, being constant during a second phase, and linearly increasing with time during a third phase; and wherein the degree of opening of the at least one second valve with time is characterized by: linearly increasing with time during the first phase, being constant during the second phase, and linearly decreasing with time during the third phase.
