In a gas turbine plant with at least one compressor (1, 2) compressing intake air (10), with at least one component for heat supply (8) heating the intake air (12) compressed by the compressor (1, 2), with at least one gas turbine (3) using as a working medium the hot air (13) from the component for heat supply (8), and with at least one generator (5) coupled to the gas turbine (3), cooling means (20, 21) being present which permit the cooling of at least a portion of the intake air (10) and/or a portion of partially compressed intake air (11) within the at least one compressor (1, 2), cooling of the components is attained which protects materials and is economical and optimum, in that the cooling means (20, 21) is suitable for cooling at least a portion of the air mass flow before or within the compressor (1, 2) such that the air temperature and/or component temperature at critical places (30-38), such as at the outlet of the compressor (1, 2) or at another component of the gas turbine plant, does not exceed a prescribed maximum temperature predetermined by the thermal resistance of the component materials there, and such that temperature measuring devices (40) are arranged at at least one of the critical places (30, 38), their measured temperature value (42) being used for specific regulation or control of the cooling means (20, 21).
