Digital Control of Centrifugal Air Compressors

By Filip Niculescu, Adrian Savescu and Mirela Vasile

Abstract

The air installation consists of high-capacity centrifugal compressors which pumps in parallel in an industrial pipe. The total air flow rate of the compressors in the pipe can be adjusted by acting on the air suction valve of each compressor so that the shut-off or opening of the compressor valve can regulate the flow rate of each compressor, which results in total flow control. The problem is to replace the analog control of the compressors with a digital control. If we have two types of compressors in the plant, the automatic setting involves closing or opening the suction valve of the compressors in a certain order so that besides the total objective to pump a particular flow we also have high energy efficiency
