  • Patent number: 11486408
    Abstract: An antisurge controller for a turbocompressor system stores multiple control algorithms in a memory for the antisurge controller. The antisurge controller identifies capabilities of field devices in the turbocompressor system. The field devices include an antisurge valve and multiple sensors. The antisurge controller selects one of the multiple control algorithms based on the identified capabilities and applies the selected control algorithm to the turbocompressor system. The selected control algorithm provides the smallest surge control margin, of the surge control margins in the multiple control algorithms, that are supported by the identified capabilities.

  • Publication number: 20200131927
    Abstract: Automatic testing for control valves is provided for diagnosing of actuators, including actuators not equipped with analog or discrete position transmitters. A valve controller confirms steady-state conditions for a turbo-compressor system that includes a control valve in a first position and sends, to an actuator for the control valve, a signal to initiate a partial valve stroke to move the control valve away from the first position. The valve controller receives feedback signals from sensors in the turbo-compressor system and monitors the feedback signals for a change from the steady-state conditions. When the monitoring detects a change from the steady-state conditions within a defined time period, the valve controller sends, to the actuator, a signal to return the control valve to the first position. When the monitoring does not detect a change from the steady-state conditions within the defined time period, the valve controller generates an alarm signal.

  • Patent number: 8342794
    Abstract: A system includes a compressor and a control system. The control system includes a processor and associated memory. The control system is configured to receive feedback comprising a thermodynamic characteristic or a mechanical characteristic of the compressor. Also, the control system is configured to generate an indication of a surge event or a stall event in the compressor based on the feedback.

  • Patent number: 5743715
    Abstract: Balancing the load between compressors is not trivial. An approach is disclosed to balance loads for compression systems which have the characteristic that the surge parameters, S, change in the same direction with rotational speed during the balancing process. Load balancing control involves equalizing the pressure ratio, rotational speed, or power (or functions of these) when the compressors are operating far from surge. Then, as surge is approached, all compressors are controlled, such that they arrive at their surge control lines simultaneously.
