Abstract

A method for power distribution network analysis includes receiving power distribution network event data from a plurality of data sources, filtering the power distribution network event data, normalizing the power distribution network event data, storing the power distribution network event data in an event database and retrieving, in a querying engine, the power distribution network event data.

Claims

1. A method for power distribution network analysis, the method comprising:

receiving power distribution network data, space weather data, media data, and weather data from a plurality of data sources, wherein a data structure type generated at one of the plurality of data sources is different than a data structure type generated at another of the plurality of data sources, the media data being associated with at least one area-wide convention, wherein the at least one area-wide convention historically resulting in a power distribution network event;

filtering the power distribution network data to provide power distribution network event data that falls outside of a threshold;

filtering the weather data to provide weather event data that falls outside of a predetermined range of values;

filtering the space weather data to provide space weather event data that falls outside of the predetermined range of values;

filtering the media data to provide media data event data that falls outside of the predetermined range of values;

normalizing the power distribution network event data, the space weather event data, the media event data, and the weather event data to transform the data structure types from the plurality of data sources to a single data structure type for the plurality of data sources;

storing the power distribution network event data in an event database; and

retrieving, in a querying engine, the power distribution network event data, the space weather event data, the media event data, and the weather event data using a query related to a current event; and

analyzing the retrieved power distribution network event data, the space weather event data, the media event data, and the weather event data to manage the current event.

2. The method as claimed in claim 1 wherein the power distribution network event data retrieved by the querying engine is disseminated to a plurality of interfaces.

3. The method as claimed in claim 1 wherein the power distribution network event data retrieved by the querying engine is disseminated to a plurality of analysis tools.

4. The method as claimed in claim 1 wherein the querying engine is configured to retrieve data values and ranges for the power distribution network event data related to a particular power distribution network event.

5. The method as claimed in claim 1 wherein the querying engine is configured to retrieve data related to historic power distribution network events matching criteria related to a particular power distribution network event.

6. The method as claimed in claim 1 wherein the querying engine is configured to retrieve time data for a time period related to a particular power distribution network event.

7. The method as claimed in claim 1 wherein the power distribution network event data is filtered to retrieve relevant data that contributes to power distribution network events.

8. A computer program product including a non-transitory computer readable medium storing instructions for causing a computer to implement a method for power distribution network analysis, the method comprising:

receiving power distribution network data, space weather data, media data, and weather data from a plurality of data sources, wherein a data structure generated at one of the plurality of data sources is different than a data structure type generated at another of the plurality of data sources, the media data being associated with at least one area-wide convention, wherein the at least one area-wide convention historically resulted in a power distribution network event;

filtering the power distribution network event data to provide power distribution network event data that falls outside of a threshold;

filtering the weather data to provide weather event data that falls outside of a predetermined range of values;

filtering the space weather data to provide space weather event data that falls outside of the predetermined range of values;

filtering the media data to provide media data event data that falls outside of the predetermined range of values;

normalizing the power distribution network event data, the space weather event data, the media event data, and the weather data to transform the data structure types from the plurality of data sources to a single data structure type;

storing the power distribution network event data in an event database;

retrieving, in a querying engine, the power distribution network event data, the space weather event data, the media event data, and the weather event data using a query related to a current event; and

analyzing the retrieved power distribution network event data, the space weather event data, the media event data, and the weather event data to manage the current event.

9. The computer program product as claimed in claim 8 wherein the power distribution network event data retrieved by the querying engine is disseminated to a plurality of interfaces.

10. The computer program product as claimed in claim 8 wherein the power distribution network event data retrieved by the querying engine is disseminated to a plurality of analysis tools.

11. The computer program product as claimed in claim 8 wherein the querying engine is configured to retrieve data values and ranges for the power distribution network event data related to a particular power distribution network event.

12. The computer program product as claimed in claim 8 wherein the querying engine is configured to retrieve data related to historic power distribution network events matching criteria related to a particular power distribution network event.

13. The computer program product as claimed in claim 8 wherein the querying engine is configured to retrieve time data for a time period related to a particular power distribution network event.

14. The computer program product as claimed in claim 8 wherein the power distribution network event data is filtered to retrieve relevant data that contributes to power distribution network events.

15. A system for power distribution network analysis, the system comprising:

a querying engine;

an event database communicatively coupled to the querying engine configured to store data power distribution network data, space weather data, media data, and weather data from a plurality of data sources, wherein a data structure generated at one of the plurality of data sources is different than a data structure type generated at another of the plurality of data sources, the media data being associated with at least one area-wide convention, wherein the at least one area-wide convention historically resulted in a power distribution network event;

a normalization layer coupled to the event database and configured to transform the plurality of data structure types from the plurality of data sources to a single data structure type for the plurality of data sources;

a plurality of event filters coupled to the normalization layer and configured to retrieve relevant power distribution network data, relevant space weather data, relevant media data, and relevant weather data, filter the power distribution network data to provide power distribution network event data that falls outside of a threshold, filter the weather data to provide weather event data that falls outside of a predetermined range of values, filter the space weather data to provide space weather event data that falls outside of the predetermined range of values, and filter the media data to provide media data event data that falls outside of the predetermined range of values;

wherein the querying engine retrieves the power distribution network event data, the space weather event data, the media event data, and the weather event data using a query related to a current event in order to analyze the retrieved power distribution network event data and the weather event data to manage the current event.

16. The system as claimed in claim 15, wherein the querying engine is configured to retrieve data values and ranges for the power distribution network event data related to a particular power distribution network event.
