Abstract
A method of operating turbo compressors. To prevent pumping surges, blow-off valves are opened upon reaching a blow-off line extending parallel, with respect to time, to the pumping limit. The difference between the compressor discharge pressure and flow rate and the blow-off line is non-linearly amplified in a manner related to the actual pressure and flow rate so that the amplification gain is increased if the operating point of the compressor shifts into the non-permissible range beyond the blow-off line. Special provisions are made for starting the compressor.
