Abstract

A system for use in locating a fault in a power generation and delivery system is provided. The system includes a fault detection module configured to detect an occurrence of the fault and to generate a fault event notification, a satellite imaging system configured to acquire satellite image data, and a fault location module coupled to the fault detection module and to the satellite imaging system, the fault location module configured to receive the fault event notification from the fault detection module, receive satellite image data of a target area that includes the fault from the satellite imaging system, and determine the location of the fault based on the satellite image data.

Claims

1. A system for use in locating a fault in a power generation and delivery system, said system comprising:

a fault detection module configured to detect an occurrence of the fault and to generate a fault event notification;

a satellite imaging system configured to acquire satellite image data; and

a fault location module coupled to said fault detection module and to said satellite imaging system, said fault location module configured to;

receive the fault event notification from said fault detection module;

receive satellite image data of a target area that includes the fault from said satellite imaging system; and

determine the location of the fault by comparing a satellite image taken before the fault occurred with a satellite image taken after the fault occurred.

2. A system in accordance with claim 1, wherein said fault location module is configured to determine the location of the fault by identifying at least one anomaly in the satellite image data.

3. A system in accordance with claim 2, wherein the at least one anomaly is at least one of a burn region, a devastation region, and a blackout region.

4. A system in accordance with claim 1, wherein said fault location module is further configured to determine the cause of the fault based on the satellite image data.

5. A system in accordance with claim 1, wherein said fault location module is further configured to merge geographic information system data with the satellite image data to determine the location of the fault.

6. A system in accordance with claim 1, wherein the fault event notification includes at least one of a time of detection of the fault and the target area.

7. A computing device for use in locating a fault in a power generation and delivery system, said computing device comprising:

a memory device configured to store satellite image data; and

a processor coupled to said memory device, said processor configured to;

receive a fault event notification;

retrieve satellite image data of a target area containing the fault from said memory device; and

determine the location of the fault by comparing a satellite image taken before the fault occurred with a satellite image taken after the fault occurred.

8. A computing device in accordance with claim 7, wherein said processor is configured to determine the location of the fault by identifying at least one anomaly in the satellite image data.

9. A computing device in accordance with claim 8, wherein the at least one anomaly is at least one of a burn region, a devastation region, and a blackout region.

10. A computing device in accordance with claim 7, wherein said processor is further configured to determine the cause of the fault based on the satellite image data.

11. A computing device in accordance with claim 7, wherein said processor is further configured to merge geographic information system data with the satellite image data to determine the location of the fault.

12. A computing device in accordance with claim 11, wherein said processor is configured to merge geographic information system data with the satellite image data by superimposing a satellite image on digital map data.

13. A computing device in accordance with claim 7, further comprising:

a display device coupled to said processor, wherein said processor is further configured to display the determined location of the fault on said display device.

14. A method for determining a location of a fault in a power generation and delivery system, said method comprising:

detecting an occurrence of the fault;

acquiring satellite image data of a target area containing the fault; and

determining the location of the fault by comparing a satellite image taken before the fault occurred with a satellite image taken after the fault occurred.

15. A method in accordance with claim 14, further comprising merging geographic information system data with the satellite image data to determine the location of the fault.

16. A method in accordance with claim 14, wherein determining the location of the fault comprises identifying at least one anomaly in the satellite image data.

17. A method in accordance with claim 14, further comprising determining the cause of the fault based on the satellite image data.
