Abstract
In accordance with one aspect of the present technique a method includes receiving at least one of a speed and an acceleration of a rotating component in a rotating machine. The method includes determining whether at least one of the speed and the acceleration of the rotating component exceeds a non-trip operating (NTO) space in a speed-acceleration plane, wherein the NTO space is based on a trip overshoot model. The method further includes sending a notification for tripping the rotating machine in response to determining that at least one of the speed and the acceleration of the rotating component exceeds the NTO space.
Claims20
A method for preventing an emergency over-speed condition in a rotating machine, the method comprising:
- receiving at least one of a speed and an acceleration of a rotating component in the rotating machine;
- determining whether at least one of the speed and the acceleration of the rotating component exceeds a non-trip operating (NTO) space in a speed-acceleration plane, wherein the NTO space is based on a trip overshoot model;
- and
- sending a notification for tripping the rotating machine in response to determining that at least one of the speed and the acceleration of the rotating component exceeds the NTO space.
A system for preventing an emergency over-speed condition in a rotating machine, the system comprising:
- at least one processor;
- a communication module stored in a memory and executable by the at least one processor, the communication module configured to receive at least one of a speed and an acceleration of a rotating component in the rotating machine;
- a determination module stored in the memory and executable by the at least one processor, the determination module communicatively coupled to the communication module and configured to determine whether at least one of the speed and the acceleration of the rotating component exceeds a non-trip operating (NTO) space in a speed-acceleration plane, wherein the NTO space is based on a trip overshoot model;
- and
- a notification module stored in the memory and executable by the at least one processor, the notification module communicatively coupled to the determination module and configured to send a notification for tripping the rotating machine in response to determining that at least one of the speed and the acceleration of the rotating component exceeds the NTO space.
A computer program product comprising a non-transitory computer readable medium encoding instructions that, in response to execution by at least one processor, cause the processor to perform operations comprising:
- receive at least one of a speed and an acceleration of a rotating component in a rotating machine;
- determine whether at least one of the speed and the acceleration of the rotating component exceeds a non-trip operating (NTO) space in a speed-acceleration plane, wherein the NTO space is based on a trip overshoot model;
- and
- send a notification for tripping the rotating machine in response to determining that at least one of the speed and the acceleration of the rotating component exceeds the NTO space.
