Abstract

Systems, methods and computer program products enable the remote monitoring of the combustion dynamics of turbines. Remote monitoring permits a single user to continuously monitor the operating health of a fleet of turbines simultaneously from a single location. The user is presented with one or more graphical user interfaces that graphically display combustion dynamics data to enable the user to visually and quickly determine whether the turbine is operating within prescribed limits. The system permits the user to determine whether each turbine is operating to its maximum efficiency.

Claims

1. A system for monitoring a plurality of turbines, comprising:

at least one turbine;

at least one combustion dynamics monitoring device, in communication with the at least one turbine, wherein the at least one combustion dynamics monitoring device is operable to measure the pressure within at least one combustion chamber of the at least one turbine; and

at least one fleet server, wherein the at least one fleet server is in remote communication with the at least one combustion dynamics monitoring device, and wherein the at least one fleet server is operable to generate a graphical display illustrating the operational status of the at least one turbine.

2. The system of claim 1, further comprising at least one turbine monitoring device, in communication with the at least one turbine, wherein the at least one turbine monitoring device is operable to monitor non-pressure related information associated with the at least one turbine.

3. The system of claim 2, wherein the at least one fleet server is in communication with the at least one turbine monitoring device, and wherein the at least one fleet server receives the non-pressure related information from the at least one turbine monitoring device.

4. The system of claim 1, wherein the graphical display generated by the at least one fleet server illustrates the pressure within the at least one combustion chamber of the at least one turbine.

5. The system of claim 4, wherein the graphical display generated by the at least one fleet server simultaneously illustrates the pressure within the at least one combustion chamber of a plurality of turbines.

6. The system of claim 1, wherein the at least one combustion dynamics monitoring device is further operable to generate frequency information revealing acoustic vibrations in the at least one turbine.

7. The system of claim 6, wherein the frequency information comprises the maximum pressure within each of the at least one combustion chamber of the at least one turbine.

8. The system of claim 6, wherein the frequency information reveals acoustic vibrations in the at least one turbine in a plurality of frequency bands.

9. The system of claim 8, wherein the plurality of frequency bands exist within the frequency ranges of 0 to about 3200 Hertz.

10. The system of claim 1, wherein the graphical display generated by the fleet server identifies the combustion chamber having a maximum pressure value measured by the at least one combustion dynamics monitoring device.

11. The system of claim 1, wherein the graphical display generated by the fleet server further comprises the site location of the at least one turbine.

12. The system of claim 1, wherein the at least one fleet server is accessible by users via the Internet.

13. A method for monitoring a plurality of turbines, comprising:

using at least one combustion monitoring device to monitor the pressure within at least one combustion chamber of at least one turbine;

communicating the monitored pressure to at least one fleet server in communication with the at least one combustion monitoring device; and

displaying, using the fleet server, the operational status of the at least one turbine.

14. The method of claim 13, further comprising the step of using at least one turbine monitoring device to monitor non-pressure related information associated with the at least one turbine.

15. The method of claim 14, further comprising the step of receiving, at the at least one fleet server, the non-pressure related information.
