A method is provided for operating a stationary internal combustion machine including a compressor device of variable compressor geometry which compresses gas fed to the internal combustion machine, and a throttle device which is connected downstream of the compressor device and with which the amount of compressed gas fed to the internal combustion machine is variable. The internal combustion machine is regulated by way of the actuation of at least two adjusting members, wherein the internal combustion machine is regulated to a—preferably substantially constant—engine regulating value. Upon a deviation in the engine regulating value from a reference value, the amount of gas fed to the internal combustion machine is altered by the actuation of the throttle device as the first adjusting member and by the variation in the geometry of the compressor device as the second adjusting member so that the engine regulating value is re-set to the reference value.
