Abstract: A method for avoiding pump surges in a compressor is provided, wherein a plurality of parameters of the compressor are monitored during operation and a desired value range for the plurality of parameters is predetermined, wherein a reaction that counteracts the pump surge is triggered if a number of parameters from the desired value range are exceeded or fallen below. The method also reliably prevents pumping of the compressor during a comparatively high running performance. For this purpose, the plurality of parameters has a parameter assigned to the rotational noise of the compressor.

Abstract: A method for operating a gas turbine comprising a compressor, a combustion chamber and a turbine is to allow a particularly safe and reliable operation of the gas turbine. Furthermore, a gas turbine and gas and steam turbine plant, which are especially suitable for carrying out the method, are disclosed. For this purpose, the compressor discharge pressure is used as a control variable.
