Description
BACKGROUND
[0001] Machinery having rotating shafts such as turbines,
automobiles, trains, electric motors and the like utilize overspeed
systems to prevent and/or warn of dangerous overspeed conditions of
the shaft and vibration sensing systems to monitor/warn/prevent
dangerous vibration conditions. Overspeed systems typically utilize
a proximity sensor sensing passage of teeth on a toothed wheel. The
number of teeth on the wheel is a manual data entry in the
overspeed system, subject to entry error. The vibration sensing
system is located on the same shaft as the overspeed system, and
typically includes a keyphasor, which senses, for example, a
protrusion on the shaft once per revolution. The invention is using
the information on shaft speed from the vibration system to check
the configuration of the overspeed sensing system.
[0002] Manual errors can occur during configuration of the
overspeed system and/or a control system, wherein the incorrect
number of teeth on the toothed wheel can be entered into the
control system for turbine overspeed. This can result in incorrect
speed sensing, which can lead to the overspeed of and damage to the
rotating machinery.
[0003] Therefore, what is desired are systems and methods where
configuration errors can be detected and corrected before initial
full speed run of rotating machinery without adding additional
hardware, complexity, or cost to the overall control system.
SUMMARY
[0004] Disclosed herein is a method of verifying the configuration
of an overspeed system for a shaft. The method comprises
determining a first rotational speed of a shaft using an overspeed
system. The overspeed system comprises a toothed wheel that rotates
in relation to the rotational speed of the shaft. In one aspect,
the overspeed system may further comprise a proximity sensor that
detects each tooth of the toothed wheel as each tooth passes by the
proximity sensor. The method further comprises determining a second
rotational speed of the shaft using a vibration sensing system for
monitoring vibration of the shaft. In one aspect, the vibration
sensing system may further comprise a keyphasor on the shaft and a
sensor used to determine when the keyphasor passes by the sensor,
said vibration sensing system creating a keyphasor signal each time
the keyphasor passes by the sensor. The method further comprises
comparing the first rotational speed of the shaft and the second
rotational speed of the shaft to verify a configuration of the
overspeed system.
[0005] In one aspect, verifying the configuration of the overspeed
system comprises determining whether a previously set tooth count
configuration used by the overspeed system to determine the speed
of the shaft is set to accurately reflect a count of teeth on the
toothed wheel. If the comparison of the first rotational speed of
the shaft and the second rotational speed of the shaft is not
equal, the previously set tooth count configuration used by the
overspeed system can be set to the count of teeth on the toothed
wheel.
[0006] In various aspects, if the comparison of the first
rotational speed of the shaft and the second rotational speed of
the shaft is not equal, a warning is provided through the overspeed
system and/or the vibration sensing system. In another aspect, if
the comparison of the first rotational speed of the shaft and the
second rotational speed of the shaft is not equal, a machine
utilizing the shaft is prevented from operating.
[0007] In various aspects, the machine utilizing the shaft may
comprise a gas turbine, steam turbine, wind turbine, a
liquid-driven turbine, an automobile, a train, an electric motor or
any other machine having a rotating shaft.

the configuration of an overspeed system. The system comprises a
machine having a shaft; an overspeed system, wherein the overspeed
system determines a first rotational speed of the shaft using a
toothed wheel that rotates in relation to a speed of the shaft. In
one aspect, the overspeed system further comprises a proximity
sensor that detects each tooth of the toothed wheel as each tooth
passes by the proximity sensor. The system further comprises a
vibration sensing system for monitoring vibration of the shaft,
wherein the vibration sensing system determines a second rotational
speed of the shaft. In one aspect, the vibration sensing system
further comprises a keyphasor on the shaft and a sensor used to
determine when the keyphasor passes by the sensor, said vibration
sensing system creating a keyphasor signal each time the keyphasor
passes by the sensor. Further comprising the system is a processor,
wherein the processor: receives the first rotational speed of the
shaft from the overspeed system; receives the second rotational
speed of the shaft from the vibration sensing system; and compares
the first rotational speed of the shaft and the second rotational
speed of the shaft to verify a configuration of the overspeed
system for the machine.
[0009] In one aspect, verifying the configuration of the overspeed
system for the machine comprises determining whether a previously
set tooth count configuration used by the overspeed system to
determine the speed of the shaft is set to accurately reflect a
count of teeth on the toothed wheel. If the comparison of the first
rotational speed of the shaft and the second rotational speed of
the shaft is not equal, the previously set tooth count
configuration used by the overspeed system can be set by the
processor to the count of teeth on the toothed wheel.
[0010] In various aspects, if the comparison of the first
rotational speed of the shaft and the second rotational speed of
the shaft is not equal, a warning is provided through the overspeed
system and/or through the vibration sensing system and/or by the
processor. In one aspect, if the comparison of the first rotational

[0026] FIGS. 1A and 1B are illustrations of exemplary systems for
verifying the configuration of an overspeed system. As shown in
FIGS. 1A and 1B, in one aspect the system can comprise a machine
102, wherein the machine 102 further comprises a shaft 104 that can
rotate. For example, the machine 102 can be a turbine such as a
gas, steam, wind or liquid-driven turbine. It also can be any other
rotating machine such as a vehicle (e.g., train, automobile, etc.)
having an axle or drive shaft or an electric motor having a
rotating shaft. Further comprising the illustrated system is an
overspeed system 106. Generally, the overspeed 106 system is an
electronic overspeed detection system that is typically used on
rotating machinery. Overspeed systems 106 comprise tachometer
modules that are used to monitor the speeds of the rotating shaft
of rotating machinery and provide warnings and/or trip signals if
the shaft is rotating outside of a desired speed or at a speed that
could damage the machine or create a safety hazard. Such overspeed
systems are available from, for example, Bently Nevada Inc., a
wholly owned subsidiary of General Electric Company (Minden, Nev.),
such as the Bently Nevada 3500/53 Electronic Overspeed Detection
System. As shown in FIGS. 1A and 1B, the overspeed system 106
determines a first rotational speed of the shaft 104 using a
toothed wheel 108 that rotates in relation to a speed of the shaft
104. While the toothed wheel 108 illustrated in FIGS. 1A and 1B is
mounted directly to the shaft and therefore rotates in a 1:1
relationship with the shaft 104, it is to be appreciated that in
other instances the toothed wheel 108 may be a part of a geared
system such that the toothed wheel rotates faster or slower than
the shaft 104, but the rotation of the toothed wheel 108 is always
in relation to and corresponds with the rotation of the shaft 104.
In one aspect, the overspeed system 106 further comprises a
proximity sensor 112 that detects each tooth of the toothed wheel
108 as each tooth passes by the proximity sensor 112. The proximity
sensor 112 provides an electronic signal to the overspeed system
for each tooth of the toothed wheel 108 that passes near the
proximity sensor. The signal from the proximity sensor 112 is
received at an interface of the overspeed system 106 and is
processed by a processor associated with the overspeed system 106.
As used herein, processor refers to a physical hardware device that
executes encoded instructions for performing functions on inputs
and creating outputs. Exemplary processors for use in this
disclosure are described herein in relation to FIG. 3.
[0027] Further comprising the systems of FIGS. 1A and 1B is a
vibration sensing system 110 for monitoring vibration of the shaft
104. Generally, a vibration sensing system is used to monitor
vibration of the shaft 104 during operation of the machine. If
vibrations exceed predefined limits, the vibration sensing system
110 can issue warnings and/or trip signals to shut down operation
of the machine. Vibration sensing systems also generally monitor
the rotational speed of the shaft 104. This is because vibrations
at some speeds (e.g., lower speeds) may be acceptable while the
same or similar vibrations at higher speeds may not be acceptable.
Therefore, as shown in FIGS. 1A and 1B, the vibration sensing
system 110 determines a second rotational speed of the shaft 104.
Vibration sensing systems are available from Bently Nevada Inc.,
among others. As shown in FIGS. 1A and 1B, the vibration sensing
system 110 further comprises a keyphasor 114 on the shaft and a
sensor 116 used to determine when the keyphasor 114 passes by the
sensor 116. In this way, the vibration monitoring system 110 can
monitor the speed of the shaft 104. The vibration sensing system
110 receives a keyphasor signal each time the keyphasor 114 passes
by the sensor 116.
[0028] Further comprising the systems of FIGS. 1A and 1B is a
processor. In one aspect, the processor is a portion of the
vibration sensing system 110, the overspeed system 106, or, as
shown in FIG. 1B, the processor can be a part of a control system
118 for the machine 102. In one aspect, the processor may comprise
a plurality of processors that are in communication with one
another. For example, the processor of the overspeed system 106 may
be in communication with the processor of the vibration sensing
system 110. As noted herein, processor refers to a physical
hardware device that executes encoded instructions for performing
functions on inputs and creating outputs. Exemplary processors for
use in this disclosure are described herein in relation to FIG. 3.
Regardless of the location of the processor, it receives the first
rotational speed of the shaft from the overspeed system 106;
receives the second rotational speed of the shaft from the
vibration sensing system 110; and compares the first rotational
speed of the shaft 104 and the second rotational speed of the shaft
104 to verify a configuration of the overspeed system 106 for the
machine 102. In one aspect, verifying the configuration of the
overspeed system 106 for the machine 102 comprises determining
whether a previously set tooth count configuration used by the
overspeed system 106 to determine the speed of the shaft 104 is set
to accurately reflect a count of teeth on the toothed wheel 108. In
one aspect, if the first rotational speed of the shaft 104 and the
second rotational speed of the shaft 104 are not equal, the
previously set tooth count configuration used by the overspeed
system 106 is set by the processor to the count of teeth on the
toothed wheel 108. Also, in some aspects, if the comparison of the
first rotational speed of the shaft 104 and the second rotational
speed of the shaft 104 is not equal, a warning is provided through
the overspeed system 106 and/or if the comparison of the first
rotational speed of the shaft 104 and the second rotational speed
of the shaft 104 is not equal, a warning is provided through the
vibration sensing system 110. In yet another aspect, if the
comparison of the first rotational speed of the shaft 104 and the
second rotational speed of the shaft 104 is not equal, a warning is
provided by the processor. In some aspects, if the comparison of
the first rotational speed of the shaft 104 and the second
rotational speed of the shaft 104 is not equal, the machine 102 is
prevented from operating by the processor.
[0029] FIG. 2 is a flowchart that illustrates an exemplary method
of verifying the configuration of an overspeed system for a shaft.
In FIG. 2, the method comprises 202, determining a first rotational
speed of a shaft using an overspeed system. In one aspect, the
overspeed system comprised a toothed wheel that rotates in relation
to the rotational speed of the shaft. In one aspect, the overspeed
system that determines the first rotational speed of the shaft
using the toothed wheel that rotates in relation to the rotational
speed of the shaft comprises a proximity sensor that detects each
tooth of the toothed wheel as each tooth passes by the proximity
sensor. At 204, a second rotational speed of the shaft is
determined using a vibration sensing system for monitoring
vibration of the shaft. In one aspect, the vibration sensing system
that determines the second rotational speed of the shaft comprises
a keyphasor on the shaft and a sensor used to determine when the
keyphasor passes by the sensor, said vibration sensing system
creating a keyphasor signal each time the keyphasor passes by the
sensor. At 206, the first rotational speed of the shaft and the
second rotational speed of the shaft are compared to verify a
configuration of the overspeed system. In one aspect, verifying the
configuration of the overspeed system comprises determining whether
a previously set tooth count configuration used by the overspeed
system to determine the speed of the shaft is set to accurately
reflect a count of teeth on the toothed wheel. In one aspect, if
the comparison of the first rotational speed of the shaft and the
second rotational speed of the shaft is not equal, the previously
set tooth count configuration used by the overspeed system is set
to the count of teeth on the toothed wheel. In other various
aspects, if the comparison of the first rotational speed of the
shaft and the second rotational speed of the shaft is not equal, a
warning is provided through the overspeed system and/or through the
vibration sensing system. In one aspect, if the comparison of the
first rotational speed of the shaft and the second rotational speed
of the shaft is not equal, a machine utilizing the shaft is
prevented from operating. The machine may be, for example, a gas
turbine, steam turbine, wind turbine, a liquid-driven turbine, an
automobile, a train, an electric motor, and the like.
[0030] The system has been described above as comprised of units.

for verifying the configuration of an overspeed system for a shaft.
In various aspects, the computer of FIG. 3 may comprise all or a
portion of the overspeed system 106, the vibration sensing system
110, and/or the control system 118, as described herein. As used
herein, "computer" may include a plurality of computers. The
computers may include one or more hardware components such as, for
example, a processor 321, a random access memory (RAM) module 322,
a read-only memory (ROM) module 323, a storage 324, a database 325,

Processor 321 may be configured to execute sequences of computer
program instructions to perform various processes. The computer
program instructions may be loaded into RAM 322 for execution by
processor 321.
[0033] RAM 322 and ROM 323 may each include one or more devices for
storing information associated with operation of processor 321. For
example, ROM 323 may include a memory device configured to access
and store information associated with controller 320, including

[0034] Storage 324 may include any type of mass storage device
configured to store information that processor 321 may need to
perform processes consistent with the disclosed embodiments. For
example, storage 324 may include one or more magnetic and/or
optical disk devices, such as hard drives, CD-ROMs, DVD-ROMs, or
any other type of mass media device.
[0035] Database 325 may include one or more software and/or
hardware components that cooperate to store, organize, sort,
filter, and/or arrange data used by controller 320 and/or processor
321. For example, database 325 may store the first rotational speed
of a shaft as determined using an overspeed system, the second
rotational speed of the shaft as determined using a vibration
sensing system for monitoring vibration of the shaft, and the
results of a comparison of the first rotational speed of the shaft
and the second rotational speed of the shaft to verify a
configuration of the overspeed system. It is contemplated that
database 325 may store additional and/or different information than
that listed above.
[0036] I/O devices 326 may include one or more components
configured to communicate information with a user associated with
controller 320. For example, I/O devices may include a console with
an integrated keyboard and mouse to allow a user to maintain a
database of images, update associations, and access digital
content. I/O devices 326 may also include a display including a
graphical user interface (GUI) for outputting information on a
monitor. I/O devices 326 may also include peripheral devices such
as, for example, a printer for printing information associated with
controller 320, a user-accessible disk drive (e.g., a USB port, a
floppy, CD-ROM, or DVD-ROM drive, etc.) to allow a user to input
data stored on a portable media device, a microphone, a speaker
system, or any other suitable type of interface device.
[0037] Interface 327 may include one or more components configured
to transmit and receive data via a communication network, such as
the Internet, a local area network, a workstation peer-to-peer
network, a direct link network, a wireless network, or any other
suitable communication platform. For example, interface 327 may
include one or more modulators, demodulators, multiplexers,
demultiplexers, network communication devices, wireless devices,
antennas, modems, and any other type of device configured to enable
data communication via a communication network.
[0038] While the methods and systems have been described in
connection with preferred embodiments and specific examples, it is
not intended that the scope be limited to the particular
embodiments set forth, as the embodiments herein are intended in
all respects to be illustrative rather than restrictive.
[0039] Unless otherwise expressly stated, it is in no way intended
that any method set forth herein be construed as requiring that its
steps be performed in a specific order. Accordingly, where a method
claim does not actually recite an order to be followed by its steps
or it is not otherwise specifically stated in the claims or
descriptions that the steps are to be limited to a specific order,
it is no way intended that an order be inferred, in any respect.
This holds for any possible non-express basis for interpretation,
including: matters of logic with respect to arrangement of steps or
operational flow; plain meaning derived from grammatical
organization or punctuation; the number or type of embodiments
described in the specification.
[0040] Throughout this application, various publications are
referenced. The disclosures of these publications in their
entireties are hereby incorporated by reference into this
application in order to more fully describe the state of the art to
which the methods and systems pertain.
[0041] It will be apparent to those skilled in the art that various
modifications and variations can be made without departing from the
scope or spirit. Other embodiments will be apparent to those
skilled in the art from consideration of the specification and
practice disclosed herein. It is intended that the specification
and examples be considered as exemplary only, with a true scope and
spirit being indicated by the following claims.
