Abstract

The invention relates to a method for operating one or multiple compressors (110, 120, 130, 140), wherein the multiple compressors are arranged in series for compressing a fluid (a) in successive manner, in particular in order to achieve a pre-defined suction pressure upstream of the one or the most upstream one (110) of the multiple compressors, wherein for the one or each of the multiple compressors, a safety operating correlation and an optimum operating correlation are provided, wherein each of the safety operating correlation and the optimum operating correlation provide a correlation between a rotational speed of the respective compressor and a volume flow of fluid through the respective compressor, wherein each of the safety operating correlations is defined with a respective safety margin to a respective surge limit of the respective compressor, wherein each of the optimum operating correlations is shifted, with respect to the respective safety operating correlation, towards higher volume flows and/or lower rotational speeds, the method comprising, for the one or each of the multiple compressors: controlling a pressure at an inlet of the compressor by adjusting a rotational speed of the respective compressor, such that an operating point of the compressor does not go beyond a current operating correlation towards the surge limit, wherein the current operating correlation is between the respective safety operating correlation and the respective optimum operating correlation or equal to one of them
