Abstract

A method for identifying conditions that correlate with one ore more events related to operation of a power grid. The method includes the determining one or more distinguishing characteristics of a first chunk. The first chunk includes data elements relevant to operating a power grid. The method also includes determining whether a distinguishing characteristic of the first chunk correlates with a distinguishing characteristic of one or more of a plurality of second chunks. Each second chunk includes a plurality of data elements corresponding with the data of the first chunk. The method further includes determining whether a second chunk, having a distinguishing characteristic equivalent to a distinguishing characteristic of the first chunk, is associated with the one or more events. In addition, the method includes determining whether a second chunk, having an association with the one or more events and a distinguishing characteristic equivalent to a distinguishing characteristic of the first chunk, is substantially identical to the first chunk.

Claims

1. A method for identifying conditions that correlate with one or more events related to operation of a power grid, comprising:

determining one or more distinguishing characteristics of a first chunk, the first chunk including data elements relevant to operating a power grid;

determining whether a distinguishing characteristic of the first chunk correlates with a distinguishing characteristic of one or more of a plurality of second chunks, each second chunk including a plurality of data elements corresponding with the data of the first chunk.

determining whether a second chunk, having a distinguishing characteristic equivalent to a distinguishing characteristic of the first chunk, is associated with the one or more events; and

determining whether a second chunk, having an association with the one or more events and a distinguishing characteristic equivalent to a distinguishing characteristic of the first chunk, is substantially identical to the first chunk.

2. The method of claim 1, further comprising:

generating an alert as to a result of the determination of whether the first and second chunks are substantially identical.

3. The method of claim 1, further comprising:

adjusting the power grid in response to a determination that a second chunk is substantially identical to the first chunk.

4. The method of claim 1, further comprising storing the first chunk.

5. The method of claim 4, further comprising storing the distinguishing characteristics of the first chunk in an index.

6. The method of claim 1, wherein the determining of whether a second chunk having an association with the one or more events and a distinguishing characteristic equivalent to a distinguishing characteristic of the first chunk is substantially identical to the first chunk includes comparing each pair of corresponding bytes of the first and second chunks.

7. The method of claim 1, wherein the determining whether a distinguishing characteristic of the first chunk correlates with a distinguishing characteristic of one or more of a plurality of second chunks is performed in real time.

8. The method of claim 1, wherein the data elements of the second chunk are associated with a first time and the data elements of the first chunk are associated with a second time, the first time preceding the second time.

9. A power grid controller, comprising:

a distinguishing characteristic calculator to determine one or more distinguishing characteristics of a first chunk, the first chunk including data elements relevant to operating a power grid;

a similarity comparator to determine whether a distinguishing characteristic of the first chunk correlates with a distinguishing characteristic of one or more of a plurality of second chunks, each second chunk including a plurality of data elements corresponding with the data of the first chunk;

an event comparator to determine whether a second chunk, having a distinguishing characteristic equivalent to a distinguishing characteristic of the first chunk, is associated with one or more events; and

an identity determiner to determine whether a second chunk having an association with the one or more events and a distinguishing characteristic equivalent to a distinguishing characteristic of the first chunk is substantially identical to the first chunk.

10. The power grid controller of claim 9, further comprising:

a user interface, which the power grid controller may generate an alert as to a result of the determination of whether the first and second chunks are substantially identical.

11. The power grid controller of claim 9, wherein the power grid controller adjusts a power grid in response to a determination that a second chunk is substantially identical to the first chunk.

12. The power grid controller of claim 9, further comprising a storage repository to store the plurality of second chunks.

13. The power grid controller of claim 9, further comprising a memory to store an index of distinguishing characteristics.

14. A computer readable storage medium having instructions stored thereon which, when executed, cause a processor to perform the following operations:

determining one or more distinguishing characteristics of a first chunk, the first chunk including data elements relevant to operating a power grid;

determining whether a distinguishing characteristic of the first chunk correlates with a distinguishing characteristic of one or more of a plurality of second chunks, each second chunk including a plurality of data elements corresponding with the data of the first chunk.

determining whether a second chunk, having a distinguishing characteristic equivalent to a distinguishing characteristic of the first chunk, is associated with one or more events; and

determining whether a second chunk having an association with the one or more events and a distinguishing characteristic equivalent to a distinguishing characteristic of the first chunk is substantially identical to the first chunk.

15. The storage medium of claim 14, further comprising:

generating an alert as to a result of the determination of whether the first and second chunks are substantially identical.

16. The storage medium of claim 14, further comprising the operation of:

adjusting the power grid in response to a determination that a second chunk is substantially identical to the first chunk.

17. The storage medium of claim 14, further comprising the operation of storing the first chunk.

18. The storage medium of claim 17, further comprising storing the distinguishing characteristics of the first chunk in an index.

19. The storage medium of claim 14, wherein the determining of whether a second chunk having an association with the one or more events and a distinguishing characteristic equivalent to a distinguishing characteristic of the first chunk is substantially identical to the first chunk includes comparing each pair of corresponding bytes of the first and second chunks.

20. The storage medium of claim 14, wherein the data elements of the second chunk are associated with a first time and the data elements of the first chunk are associated with a second time, the first time preceding the second time.
