Abstract

Combining and analyzing streamed and polled electric power delivery system information is disclosed herein. A system therefore includes a plurality of IEDs in communication with the electric power distribution system and configured to provide streaming and/or polled data via a communications network. An analysis engine in communication with the communications network receives selected streaming information and requested polled information, analyzes such streamed and polled information, and provides a display of such streaming and polled information to a user.

First claim

What is claimed is:

1. A system for monitoring an electric power delivery system by gathering streamed and polled data therefrom, comprising:
a plurality of intelligent electronic devices (“IEDs”) each in electrical communication with the electric power delivery system for obtaining electric power measurements from a plurality of portions of the electric power delivery system, each IED of the plurality of IEDs comprising a processor and a computer-readable storage medium that includes instructions that when executed cause the IED to:
format streaming data using the obtained electric power measurements for streaming transmission;
stream the streaming data according to a streaming protocol without continuous request;
record polled data, and
upon request transmit the recorded polled data;

a communications network in communication with each of the plurality of IEDs receiving therefrom the streamed data and upon request the polled data;
an analysis engine in communication with the communications network including:
a receiver in communication with the communication network, comprising:
a streaming interface configured to receive the continuous stream of streaming data; and
a polling interface configured to issue poll requests to selected IEDs of the plurality of IEDs and receive the polled data;

a processor;
a non-transitory computer-readable storage medium in communication with the receiver and the processor, the computer-readable storage medium including instructions that when executed cause the analysis engine to:
store the streaming data and the polled data;
format a portion of the streaming data and a portion of the polled data into a single representation;

a server in communication with the non-transitory computer-readable storage medium and the network configured to serve polled data and streaming data to the processor; and,

a display device in communication with the analysis engine and configured to receive the single representation and to display the single representation to a user.

2. A system for monitoring electric power delivery, comprising:
a plurality of intelligent electronic devices (“IEDs”) in electrical communication with an electric power delivery system for obtaining electric power measurements from the electric power delivery system, each IED of the plurality of IEDs comprising a processor and a computer-readable storage medium that includes instructions that when executed cause the IED to:
format streaming data using the obtained electric power measurements for streaming transmission;
stream the streaming data according to a streaming protocol without continuous request;
record polled data, and
upon request transmit the recorded polled data;

an analysis engine in communication with the plurality of IEDs configured to receive therefrom the streaming data and upon request the polled data; the analysis engine including:
a processor;
a non-transitory computer-readable storage medium for receiving and storing the polled data upon request and receiving the continuous stream of streaming data without continued request, and including instructions that when executed cause the processor to format a portion of the streaming data and a portion of the polled data into a single representation; and
a server in communication with the storage media, configured to serve polled data and streaming data to the storage media; and

a display device in communication with the analysis engine and configured to receive the single representation and to display the single representation to the user.

3. The system of claim 2 , wherein the single representation comprises at least one graphical illustration of each of the streaming data and the polled data.

4. The system of claim 2 , wherein the single representation comprises a time bar indicating the time of displayed information.

5. The system of claim 2 , wherein the single representation comprises one selected from the group consisting of: a data status indicator; and event report type indicator; a search window; an equation editor; and combinations thereof.

6. The system of claim 2 , wherein the single representation comprises time stamps for displayed data.

7. The system of claim 2 , wherein the single representation is automatically updated as the analysis engine receives additional streaming data or polled data.

8. The system of claim 2 , wherein the single representation comprises information available in an off-line mode.

9. The system of claim 2 , wherein the single representation is configurable between an off-line mode and an updating mode.

10. The system of claim 2 , wherein the single representation comprises one or more sets of information selected from the group consisting of: voltage, current, temperature, pressure, angle, real power, reactive power, fluid level, and combinations thereof.

11. The system of claim 2 , wherein the single representation comprises equipment status.

12. The system of claim 11 , wherein the single representation of equipment status comprises a time stamp.

13. The system of claim 2 , wherein the single representation comprises streaming data with indicators of available polled data.

14. The system of claim 13 , wherein the display device allows a user to select an available polled data, and the display device is configured to display the polled data upon selection.

15. The system of claim 14 , wherein the display device is configured to request the selected polled data from the analysis engine upon selection by a user.

16. The system of claim 2 wherein the single representation comprises voltage magnitude contours of a geographical area.

17. The system of claim 2 , wherein the display device allows a user to select a time period, and the display device is configured to display the selected time period.

18. The system of claim 17 , wherein the display device is configured to request data from the analysis engine corresponding with the selected time period upon selection by a user.

19. The system of claim 2 , further comprising a communications processor in communication with the plurality of IEDs and with the analysis engine, the communications processor configured to receive the streamed data from the IEDs, request and receive from the IEDs the polled data, and transmit the streamed data and the polled data to the analysis engine.

20. An analysis engine for monitoring electric power, comprising:
a receiver:
in communication with a plurality of intelligent electronic devices (“IEDs”) each in electrical communication with an electric power delivery system for obtaining electric power measurements from a plurality of portions of the electric power delivery system; and,
for receiving a continuous stream of streaming data from the IEDs without continued request corresponding to electric power delivery system measurements and polled data from the IEDs upon request corresponding to electric power system measurements and an electric power system event;

a polled data non-transitory computer-readable storage medium for storing the polled data upon receipt following request;
a streaming data non-transitory computer-readable storage medium for continuously storing the continuous stream of streaming data;
a processor;
a computer-readable storage medium that includes instructions that when executed cause the analysis engine to:
format a portion of the streaming data and a portion of the polled data into a first single representation, and to transmit the single representation to a first display device for g
