| Abstract: | Considering the surge influence on centrifugal compressor,its causes were analyzed,and the approaches to producing anti-surge lines by making use of polygonal function,moving anti-surge lines,self-tuning proportional gain K and quick-opening and slow-closing circulation valve were presented to realize anti-surge control in centrifugal compressor.The results show that the anti-surge control can be achieved in CS3000 DCS system. |
