Abstract:
An anti-surge system capable of anticipating a surge event in a compressor for readying the actuator to quickly actuate the anti-surge valve from the closed position to the open position. The control system includes a compressor surge controller configured to transmit a signal to the valve positioner when the operating point of the valve is approaching the surge control line. The compressor surge controller may monitor an operating margin equal to the difference between the operating point and the surge control line, and when the operating margin falls below a prescribed threshold, the compressor surge controller may send a signal to the positioner. In turn, the positioner may vent some pressure from the actuator. In this way, the dead time of the anti-surge valve on the valve seat is minimized and the valve will react more promptly to an opening signal.
