Abstract
A method of limiting the discharge pressure for turbo compressors by means of a blowoff control which is controlled by an anti-surge controller along with means for measuring the discharge pressure and an extreme value selector as well as means for measuring the pressure flow rate and for generating a signal from a manual controller, comprises, measuring the discharge pressure, comparing the measured pressure with a desired maximum pressure to produce a pressure control signal, measuring the compressor flow rate, comparing the measured flow rate with a minimum permissible flow rate to provide a flow rate control, directing a signal from a manual controller to the value selector to generate a manual controller signal and feeding each of the pressure control signal, flow rate control signal, and manual controller signal to the anti-surge controller to provide a control of the blowoff valve in accordance therewith.
