Abstract: Systems (100) and methods (200) for protecting rotating machines (105) are provided. Measurements data collected by a plurality of sensors (110, 115) may be received (205) by a controller (120) that includes one or more computers. The plurality of sensors (110, 115) may be configured to monitor vibrations associated with the rotating machine (105). Based at least in part upon the measurements data, the controller (120) may determine (240) that a respective amplitude change for at least two of the plurality of sensors (110, 115) exceeds a threshold condition. The controller (120) may also determine (245) that the threshold condition is exceeded for a predetermined period of time. Based at least in part upon determining that the threshold condition is exceeded for a predetermined period of time, the controller (120) may identify (265) an alarm event.

Abstract: An approach for detecting rotor anomalies is disclosed. An on-site monitoring unit (125) monitors vibration measurements obtained from a rotor (110) during a transient speed operation. In one aspect, the on-site monitoring unit classifies the vibration measurements into predetermined ranges of rotor speed during the transient speed operation, determines maximum vibration data for each of the predetermined ranges of rotor speed during the transient speed operation and compiles the maximum vibration data into a snapshot of the vibration measurements obtained during the transient speed operation. A remote monitoring unit (130) detects a rotor anomaly from the snapshot of vibration measurements generated by the on-site monitoring unit (125).
