Abstract

A method and system of efficiently distributing configuration information for IEDs across one or more networks in an electrical monitoring system is disclosed. Changing configuration information is managed by a configuration management system. The IEDs in the network or networks are organized in peer relationships, each peer relationship having at least one seed IED. The configuration information is loaded to the seed IED or seed IEDs which make the configuration parameter available to other IEDs in a peer relationship with the seed IED. The other IEDs may in turn become seed IEDs for other IEDs. The configuration information therefore cascades throughout the network without further communication between the configuration management system and the selected IEDs.

Claims

1. A configurable monitoring system comprising:

at least one network;

a plurality of configurable intelligent electronic devices (IEDs) coupled to the at least one network, at least a first configurable IED being a seed IED having a peer-to-peer relationship with a second IED;

a configuration management system (CMS) coupled to the at least one network, the CMS including a storage device storing a master list of configurations of the IEDs and their associated configuration information for each of the plurality of configurable IEDs on the at least one network, wherein the CMS sends at least some part of new configuration information to the first seed IED and the at least some part of the new configuration information is transferred between the first seed IED and the at least one other second IED.

2. The system of claim 1, wherein the new configuration information includes configuration parameters each indicative of a configuration associated with corresponding ones of the IEDs or a software program for a corresponding one of the IEDs.

3. The system of claim 1, wherein the second IED determines from a list file in the seed IED whether the at least some part of new configuration information will be transferred.

4. The system of claim 3, wherein the CMS disseminates the list file for each of the IEDs coupled to the at least one network.

5. The system of claim 1, wherein the CMS disseminates an alert of the new configuration information to the plurality of IEDs over the at least one network.

6. The system of claim 5, wherein the second IED queries the first seed IED regarding whether the at least some part of the new configuration information is available.

7. The system of claim 1, wherein the second IED is in a peer relationship with a third IED and the second IED serves as a seed IED for the third IED, the third IED receiving the at least some part of the configuration information from the second IED.

8. The system of claim 1, wherein the plurality of IEDs receive conditions on when to start using the received new configuration information.

9. The system of claim 1, further comprising a second network including at least one additional IED, and wherein the second IED serves as a gateway for the CMS to the second network with the at least one additional IED.

10. The system of claim 1, wherein the at least one network includes an Ethernet network, a wireless network, or a serial network.

11. The system of claim 1, wherein the first IED stores the at least part of the new configuration information and determines whether the new configuration information matches a type of the first IED;

and the first IED not configuring itself with the new configuration information if the first IED is not of the type that matches that of the new configuration information.

12. The system of claim 11, wherein CMS selects a group of IEDs to be configured with the new configuration, and the first IED configures itself with the new configuration information if the first IED is in the selected group.

13. The system of claim 1, wherein the IEDs are one of a group including a meter, a circuit monitor, a circuit breaker, or a relay, and wherein the IED measures an electrical characteristic in the monitoring system and stores on the IED data indicative of the measured electrical characteristic.

14. The system of claim 1, wherein the plurality of IEDs are coupled to at least one of two networks coupled to the CMS.

15. The system of claim 1, wherein the first IED is designated a seed IED by the CMS.

16. The system of claim 1, wherein the IEDs each maintain a list of possible seed IEDs from the multiple IEDs for that IED.

17. The system of claim 1, wherein the second peer IED obtains a second part of the configuration information from another seed IED.

18. A method of configuring IEDs in a network via a configuration management system (CMS), the method comprising:

establishing a peer-to-peer relationship between at least a first and a second IED of a plurality of IEDs, including designating at least one first seed IED and one second peer IED respectively in the relationship;

alerting at least two of the IEDs of a change in configuration;

distributing at least some part of new configuration information from the CMS to the seed IED; and

establishing a peer-to-peer communication to the seed IED to transfer the at least some part of new configuration information to the peer IED.

19. The method of claim 18, wherein the new configuration information includes configuration parameters each indicative of a configuration associated with corresponding ones of the IEDs or a software program for a corresponding one of the IEDs.

20. The method of claim 18, wherein the peer IED determines from a list file in the seed IED whether the at least some part of new configuration information will be transferred.

21. The method of claim 22, further comprising disseminating the list file via the CMS for each of the IEDs coupled to the network.

22. The method of claim 18, further comprising disseminating an alert of the new configuration information via the CMS to the plurality of IEDs over the network.

23. The method of claim 22, wherein the peer IED queries the seed IED regarding whether the at least some part of the new configuration information is available.

24. The method of claim 18, wherein the second peer IED is in a peer relationship with a third IED and the second peer IED serves as a seed IED for the third IED, the third IED receiving the at least some part of the configuration information from the second IED.

25. The method of claim 18, wherein the plurality of IEDs receive conditions on when to start using the received new configuration information.

26. The method of claim 18, wherein the CMS is coupled to a second network including at least one additional IED, and wherein the second IED serves as a gateway for the CMS to the second network with the at least one additional IED.

27. The method of claim 18, wherein the network includes an Ethernet network, a wireless network, or a serial network.

28. The method of claim 18, further comprising:

storing the at least part of the new configuration information in the first IED;

determining whether the new configuration information matches a type of the first IED; and

not configuring the first IED with the new configuration information if the first IED is not of the type that matches that of the new configuration information.

29. The method of claim 28, further comprising:

selecting a group of IEDs to be configured with the new configuration; and

configuring the first IED with the new configuration information if the configuration matches the type of the first IED, and the first IED

30. The method of claim 18, wherein the IEDs are one of a group including a meter, a circuit monitor, a circuit breaker, or a relay, and wherein the IED measures an electrical characteristic in the monitoring system and stores on the IED data indicative of the measured electrical characteristic.

31. The method of claim 18, wherein the first IED is designated a seed IED by the CMS.

32. The method of claim 18, wherein the IEDs each maintain a list of possible seed IEDs from the multiple IEDs for that IED.

33. The method of claim 18, wherein the second peer IED obtains a second part of the configuration information from another seed IED.
