Abstract:
A gas turbine plant, comprising:at least one compressor for compressing intake air; at least one component that supplies heat for heating the air compressed by the compressor; at least one gas turbine using as a working medium hot gas from the at least one component for heat supply; at least one generator coupled to the at least one gas turbine, cooling means for cooling at least a portion of the intake air, wherein the cooling means is suitable for cooling at least a portion of intake air mass flow before the at least one compressor such that at least one of the air temperature and component temperature at critical places within the at least one gas turbine does not exceed a prescribed maximum temperature predetermined by the component materials arranged at the critical places, wherein temperature measuring devices are arranged at the location of at least one of the critical places, the temperature measurement values measured by the temperature measuring devices being used for specific regulation or control of the cooling means; and a control unit to which the temperature measurement values are supplied, and which control unit outputs control signals for the control of the cooling means, and two or more measuring devices used in combination in the control, wherein the temperature measurement value that first reaches the prescribed maximum value controls the control unit.
