SYSTEM AND METHOD OF CONTROLLING COMPRESSOR SURGE

A method and system for preventing or controlling surge in a compressor 14 having a vaned diffuser 18 measures (at 56 and 58) the static pressure differential laterally across a diffuser plane 20 and derives from that differential and from a reference static pressure (at 70) a function of those thre...

Zusammenfassung:A method and system for preventing or controlling surge in a compressor 14 having a vaned diffuser 18 measures (at 56 and 58) the static pressure differential laterally across a diffuser plane 20 and derives from that differential and from a reference static pressure (at 70) a function of those three pressures which gives an indication that the compressor is approaching a surge condition. In consequence, a bleed valve 52 is controlled so as to increase the flow through the compressor to tend to avoid the surge condition even if the load demand from the compressor is not sufficient for that purpose.
