OptiComp™ BN is an enhanced option to GE’s existing OptiComp compressor control software suite. It combines OptiComp features with GE’s Bently Nevada product line vibration monitoring for improved surge prevention and detection. OptiComp BN integrates axial and radial vibration characteristics into GE’s surge protection strategy.
Features and Benefits
Reliable indication of compressor surging, with the possibility to gauge the severity of a surge
Vibration frequency filtered to detect onset of rotating stall (incipient surge), which precedes full surge
Detection of varying conditions around or during a surge cycle, such as sudden and large changes in axial rotor displacement within a defined window, and vibration characteristics (i.e., radial vibration) and thermodynamic measurements (i.e., pressure, flow, temperature) to improve detection of compressor instability and identify “rotating stall” – a precursor to surge
Provides an alarm when rotating stall characteristics are detected in the normal operating range, typically within 10% from the surge limit line as defined in the anti-surge control system
Responses to detection of characteristics in the normal operating range can be configured, based on user preference, to automatically take protective action
Counts surge cycles and analyzes data to determine results of the surge
Utilizes process measurements that are readily available in most compressor installations, with no additional instrumentation required
