METHOD OF CONTROLLING COMPRESSOR SYSTEM FOR PREVENTING SURGE OCCURRENCE AND COMPRESSOR SYSTEM USING THE SAME

摘要

Provided is a method of controlling a compressor system including measuring variables for generating a performance curve of a compressor, calculating changing rates of the variables; comparing the calculated changing rates with preset changing rate variations; and determining a surge control line different from a preset surge control line according to the calculated changing rates if the calculated changing rates are out of ranges of the preset changing rate variations.
