ABSTRACT:
A method and apparatus for regulating power consumption while controlling surge in a centrifugal compressor are disclosed. Various operating parameters of a centrifugal compressor are measured and based upon these parameters control of the power consumption of the compressor motor via inlet guide vanes and/or diffuser vanes is achieved. Additionally, the control senses and regulates power consumption and vane positioning to control operation under surge conditions and will, if necessary, energize a blow-off valve to prevent operation under surge conditions. The control is designed to integrate compressor and motive source operation to effectively minimize power consumption while avoiding operation in the surge range.
