Abstract
A method for operating a gas turbine installation () includes sucking in a gaseous medium () by the compressor () and compressed in the compressor space, a liquid medium () being injected into the gaseous medium (), so that a two-phase flow comprising a gaseous phase and a liquid phase is formed at least in a subregion of the compressor (). The gaseous medium () is then burnt with fuel () in a combustion chamber () to form hot gases (), and the hot gases () are expanded in a turbine (), the hot components of the gas turbine installation () being cooled by cooling air () of a cooling air system. A measurement is carried out to determine whether a liquid phase is present in a region of the compressor () and/or of the cooling air system.
