Abstract

A web-based system monitors a plurality of different gas turbine plants and includes a server system that summarizes data from a plurality of plants. The system also includes a client system including a browser and a storage device for storing information. The server system is configured to be coupled to the client system and retrieves operational data from the plurality of gas turbine plants, stores the data in the centralized database, and generates graphical representations of the operational data based on the stored data. More specifically, operational data from a plurality of turbine plants is summarized and viewable remotely with the server system.

Claims

1. A method for remotely monitoring a plurality of gas turbine plants using a web-based system including a server sub-system coupled to a centralized interactive database and at least one client system, said method comprising the steps of:

retrieving operating data from equipment monitored at each gas turbine plant;

transmitting retrieved data to the centralized database at predetermined timed intervals;

providing users access to at least one of archived data and live on-line data using the web-based system; and

providing users access to data from plurality of different gas turbine plants through a web-page overview.

2. A method in accordance with claim 1 said step of retrieving data further comprises the step of using a data retrieval computer to receive operating data from each gas turbine plant.

3. A method in accordance with claim 1 wherein said step of transmitting data further comprises the step of using a data retrieval computer to transmit operating data from each gas turbine plant.

4. A method in accordance with claim 1 further comprising the step of providing internal and external users access to an alarm/alert module for summarizing at least one of an alert status and an alarm status of operating equipment.

5. A method in accordance with claim 1 further comprising the step of providing internal and external users access to a trending utility module for graphically displaying operational trending.

6. A method in accordance with claim 1 further comprising the step of providing internal and external users access to a module for on-line monitoring of operating equipment within said plurality of plants.

7. A web-based system for monitoring a plurality of different gas turbine plants, said system comprising

a client system comprising a browser;

a centralized database for storing information;

a server system configured to be coupled to said client system and said database, said server system further configured to;

retrieve operational data from the plurality of gas turbine plants;

store data in said centralized database;

summarize data from a plurality of plants in an overview; and

generate graphical representations of the operational data based on the stored data.

8. A system in accordance with claim 7 further comprising a plurality of data retrieval computers configured to:

retrieve operational data from equipment monitored at each gas turbine plant;

and transmit retrieved data to the centralized database at predetermined timed intervals.

9. A system in accordance with claim 8 further configured to provide an alert status of operating equipment monitored within the plurality of plants.

10. A system in accordance with claim 8 further configured to provide an alarm status of operating equipment monitored within the plurality of plants.

11. A system in accordance with claim 8 further configured to generate graphical operational trends of equipment monitored within the plurality of plants.

12. A system in accordance with claim 8 further configured to provide on-line monitoring of equipment monitored within the plurality of plants.

13. A system in accordance with claim 8 further configured to provide on-line monitoring of equipment monitored within the plurality of plants, including at least one of operational temperatures, operational speeds, and operational pressures.

15. A web-site according to claim 14 further configured to limit user access to operational data based on individual access privileges.

16. A web-site according to claim 15 further configured to provide access to a trending utility for graphically displaying operational trends of equipment monitored within the plurality of plants.

17. A web-site according to claim 16 further configured to provide access to an alarm/alert module for displaying at least one of an operational alarm status and an operational alert status of equipment monitored within the plurality of plants.

18. A web-site according to claim 16 further configured to display graphical representations of operational data based on retrieved operational data, said web-site further configured to receive inputs representing graphical display options.

19. A web-site in accordance with claim 18 wherein said web-site further configured to receive graphical display option inputs representing at least one of a graph type, a trend length, and an ending trend date.

14. A web-site for monitoring a plurality of gas turbine plants using a web-based system including a server system coupled to a centralized interactive database and at least one client system, the server system configured to retrieve operational data from equipment monitored at each remote gas turbine plant, said web-site configured to:

provide access to archived retrieved operational data;

provide remote access to on-line operational data; and

display data from a plurality of remote plants through a web-page.
