Compressor surge control method

Patent ·
OSTI ID:6890537
This patent describes a method of controlling surge in a centrifugal compressor having a predetermined surge condition line and providing a combined output with a base load means. It comprises: establishing a main surge control line offset from the centrifugal compressor surge condition line according to a function of pressure differentials across the centrifugal compressor and across an orifice in the inlet line of the centrifugal compressor; establishing a feed forward control signal which is a function of a variable associated with the base load means which may cause the surge condition in the centrifugal compressor; and establishing an anticipatory surge control line offset from the main surge control line as a function of the established main surge control line and the established feed forward control signal.
