Method for operating a gas turbine during load control, device for regulating the operation of a gas turbine and power plant

The method involves burning fuel (F) with combustion air in a combustion chamber (22) of the gas turbine (12), such that combustion air is supplied through an air supply line (28) and fuel is supplied through a fuel line (26). The compression air is additionally supplied from a compressor (20) to combustion chamber in order to reduce overspeed of the gas turbine rotor (16) during load control or emergency shutdown condition. Independent claims are included for the following: (1) device for controlling operation of gas turbine; and (2) power plant.
