Systems and methods for protecting rotating machines
First Claim
1. 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.

Abstract
Systems and methods for protecting rotating machines are provided. Measurements data collected by a plurality of sensors may be received by a controller that includes one or more computers. The plurality of sensors may be configured to monitor vibrations associated with the rotating machine. Based at least in part upon the measurements data, the controller may determine that a respective amplitude change for at least two of the plurality of sensors exceeds a threshold condition. The controller may also determine 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 may identify an alarm event.
