Patent ID: 8665104

Claim:
A method comprising: receiving, by a controller comprising one or more computers, measurements data collected by a plurality of sensors configured to monitor vibrations associated with a rotating machine, wherein the rotating machine comprises a gas turbine; wherein receiving measurements data collected by a plurality of sensors comprises: receiving measurements data collected by a plurality of sensors monitoring one or more bearings for a rotor associated with the rotating machine; receiving first measurements data collected by one or more sensors configured to monitor a compressor bearing associated with the gas turbine; and receiving second measurements data collected by one or more sensors configured to monitor a turbine bearing associated with the gas turbine; evaluating, by the controller, the measurements data collected by each of the plurality of sensors; determining, by the controller based at least in part upon the evaluation, whether each of the plurality of sensors is operating properly; and ignoring, by the controller, measurements data collected from one or more sensors that are not determined to be operating properly; determining, by the controller based at least in part upon the measurements data, that a respective amplitude change for at least two of the plurality of sensors exceeds a threshold condition; determining, by the controller, that the threshold condition is exceeded for a predetermined period of time; obtaining historical information associated with vibration of the rotating machine; determining, based at least in part upon a comparison of the historical information to the measurements data, that respective amplitude changes of the at least two sensors are non-repeatable events; and identifying, by the controller based at least in part upon determining that the threshold condition is exceeded for a predetermined period of time, an alarm event.
