Abstract
A dynamic compressor control is provided. The dynamic compressor control includes sensors to sense operating parameters of a compressor and a compressor analytic software package. The compressor analytic software package uses the sensed operating parameters of the compressor to generate key performance indicators. The key performance indicators are used to calculate process variables for the compressor. The dynamic compressor control uses the sensed operating parameters and the process variables calculated from the key performance indicators to provide operating alarms and/or shutdowns.
Claims21
A dynamic compressor capacity control for a compressor comprising,
- a compressor having a variable speed driver;
- a hub operatively connected to the compressor to receive sensor inputs regarding a plurality of real-time operating parameters of the compressor;
- a compressor analytic software package resident in the hub, the compressor analytic software package uses the sensor inputs received by the hub to dynamically calculate signal generator data that are key performance indicators for the compressor and setting at least one control point based on at least one of the sensor inputs, the signal generator data, or a combination thereof;
- and
- a dynamic compressor capacity control processor operatively coupled to the hub and the compressor analytic software package to receive the at least one control point, wherein the dynamic compressor capacity control processor generates a control signal that controls at least one of a position of a suction control valve, a position of a recycle valve, a driver speed of the variable speed driver, or a combination thereof to maintain operation of the compressor at the control point.

- a compressor analytic software package resident in the hub, the compressor analytic software package uses the sensor inputs received by the hub to dynamically calculate signal generator data that are key performance indicators for the compressor and determine at least a first threshold associated with each of the sensor inputs and a first threshold associated with each of the signal generator data, and setting at least one control point;
- and
- a dynamic compressor capacity control processor operatively coupled to the hub and the compressor analytic software package generates a capacity control signal to modulate at least one of a suction control valve, a recycle valve, a driver speed, or a combination thereof to maintain operation of the compressor at the at least one control point and wherein the dynamic compressor capacity control processor generates a shutdown control signal associated with each of the sensor inputs and a shutdown control signal associated with each of the signal generator data based on comparing whether each of the sensor inputs violates the associated first threshold or each of the signal generator data violates the associated first threshold, such that the compressor is operated within the associated first threshold for each of the sensor inputs and within the associated first threshold for each of the signal generator data based on the at least one control point and the compressor is shutdown by the associated shutdown control signal when the compressor is operated outside the associated first threshold for one of the sensor inputs and outside the associated first threshold for one of the signal generator data.
