Abstract

A computing device for use in performing a redundancy test on a turbine assembly and a turbine control system including a plurality of controllers each configured to independently control operation of the turbine assembly is provided. The computing device configured to be coupled to the turbine control system and configured to determine whether a plurality of test conditions are satisfied, display to a user an indication of which test conditions are satisfied, and test, in response to a user input, the plurality of controllers.

Claims

1. A computing device for use in performing a redundancy test on a turbine assembly and a turbine control system including a plurality of controllers each configured to independently control operation of the turbine assembly, said computing device configured to be coupled to the turbine control system and configured to:

determine whether a plurality of test conditions are satisfied;

display to a user an indication of which test conditions are satisfied; and

test, in response to a user input, the plurality of controllers.

2. A computing device in accordance with claim 1, wherein the computing device is configured to be coupled to a triple modular redundant control system including three controllers.

3. A computing device in accordance with claim 1, wherein to determine whether a plurality of test conditions are satisfied, said computing device is configured to:

determine whether a pre-defined system configuration is complete; and

determine whether there are any outstanding alarms.

4. A computing device in accordance with claim 1, wherein to display an indication of which test conditions are satisfied, said computing device is configured to:

display satisfied test conditions with a first indicator; and

display unsatisfied test conditions with a second indicator.

5. A computing device in accordance with claim 4, wherein the first and second indicators each include at least one of a color and a formatting applied to an associated test condition.

6. A computing device in accordance with claim 1, wherein said computing device is further configured to guide the user through a troubleshooting process when the redundancy test fails.

7. A computing device in accordance with claim 1, wherein said computing device is further configured to:

display a message indicating the redundancy test failed when the redundancy test indicates that the plurality of controllers are not capable of maintaining safe and continuous operation in the event of one or more faults within the control system; and

display a message indicating the redundancy test was successfully completed when the redundancy test indicates that the plurality of controllers are capable of maintaining safe and continuous operation in the event of one or more faults within the control system.

8. A computing device in accordance with claim 1, wherein said computing device is further configured to display information that indicates why the redundancy test failed.

9. A computing device for assisting a user in performing a redundancy test on a plurality of controllers in a control system, said computing device comprising:

a processing device configured to determine whether a plurality of test conditions are satisfied;

a presentation interface coupled to said processing device and configured to display to the user an indication of which test conditions are satisfied; and

a user input interface coupled to said processing device and configured to receive input from the user that initializes testing of the plurality of controllers.

10. A computing device in accordance with claim 9, wherein to determine whether a plurality of test conditions are satisfied, said processing device is configured to:

determine whether a pre-defined system configuration is complete; and

determine whether there are any outstanding alarms.

11. A computing device in accordance with claim 9, wherein to display an indication of which test conditions are satisfied, said presentation interface is configured to:

display satisfied test conditions with a first indicator; and

display unsatisfied test conditions with a second indicator.

12. A computing device in accordance with claim 9, wherein said presentation interface is further configured to guide the user through a troubleshooting process when the redundancy test fails.

13. A computing device in accordance with claim 9, wherein said presentation interface is further configured to:

display a message indicating the redundancy test failed; and

display a message indicating the redundancy test was successfully completed.

14. A computing device in accordance with claim 9, wherein said presentation interface is further configured to display information that indicates why the redundancy test failed.

15. A computing device in accordance with claim 9, wherein the redundancy test determines whether the plurality of controllers are capable of maintaining safe and continuous operation of the control system in the event of one or more faults within the control system.

16. A method for assisting a user in performing a redundancy test on a plurality of controllers in a control system, said method comprising:

determining, using a processing device, whether a plurality of test conditions are satisfied;

displaying to the user, on a presentation interface coupled to the processing device, an indication of which test conditions are satisfied; and

receiving, at a user input interface coupled to the processing device, input from the user that initializes testing of the plurality of controllers.

17. A method in accordance with claim 16, wherein determining whether a plurality of test conditions are satisfied comprises:

determining whether a pre-defined system configuration is complete; and

determining whether there are any outstanding alarms.

18. A method in accordance with claim 16, wherein displaying an indication of which test conditions are satisfied comprises:

displaying satisfied test conditions with a first indicator; and

displaying unsatisfied test conditions with a second indicator.

19. A method in accordance with claim 16, further comprising guiding the user through a troubleshooting process when the redundancy test fails.

20. A method in accordance with claim 16, further comprising one of:

displaying a message indicating the redundancy test failed when the redundancy test indicates that the plurality of controllers are not capable of maintaining safe and continuous operation in the event of one or more faults within the control system; and

displaying a message indicating the redundancy test was successfully completed when the redundancy test indicates that the plurality of controllers are capable of maintaining safe and continuous operation in the event of one or more faults within the control system.
