Abstract

A power control management system includes an Ethernet server and at least one Ethernet gateway to facilitate communications with at least one intelligent end device (IEDs). A control computer includes the Ethernet server which is configured to create and encapsulate messages intended for the IEDs in an industry standard format. An Ethernet gateway is also included which is configured to communicate with the server, and further configured to transmit messages received from the server to the IEDs.

Claims

1. A power control management system comprising:

at least one intelligent end device (IED);

a control computer comprising an Ethernet server configured to create and encapsulate messages intended for said IEDs, in an industry standard format;

and

an Ethernet gateway configured to communicate with said server and transmit messages to said IEDs.

2. A power control system according to claim 1 wherein said server further configured to encapsulate messages with a TCP/IP Ethernet header and footer.

3. A power control system according to claim 2 wherein said gateway further configured to extract the TCP/IP Ethernet header and footer from the encapsulated messages.

4. A power control system according to claim 3 wherein said gateway further configured to transmit messages to at least one IED.

5. A power control system according to claim 1 wherein said gateway further configured to encapsulate messages returned from said IEDs with an industry standard header and footer for transmission to said Ethernet server.

6. A power control management system according to claim 5 wherein the messages are encapsulated with a TCP/IP Ethernet header and footer.

7. A power control management system according to claim 1 wherein said server is further configured to act as a communications server for other programs resident in an applications layer.

8. A power control system according to claim 1 further comprising at least one IED configured with said Ethernet gateway.

9. A method for communicating with intelligent end devices (IEDs) in a power control management system including at least one IED, an Ethernet gateway, and a control computer including an Ethernet server, said method comprising the steps of:

electrically connecting the Ethernet gateway to the Ethernet server;

configuring the server to create and encapsulate messages intended for IEDs in an industry standard format;

configuring the gateway to remove the encapsulation from received messages for transmission to the IEDs; and

transmitting the messages to the IEDs.

10. A method according to claim 9 wherein said step of configuring the server to create and encapsulate messages comprises the step of encapsulating messages with a TCP/IP Ethernet header and footer.

11. A method according to claim 10 wherein said step of configuring the gateway to remove the encapsulation from received messages comprises the step of configuring the gateway to extract the TCP/IP Ethernet header and footer from the encapsulated messages.

12. A method according to claim 11 further comprising the steps of:

configuring the gateway to encapsulate messages returned from the IEDs with an industry standard header and footer; and

transmitting the encapsulated messages to the Ethernet server.

13. A method according to claim 12 wherein said step of configuring the gateway comprises the step of encapsulating the messages with a TCP/IP Ethernet header and footer.

14. A method according to claim 9 further comprising the step of configuring the Ethernet server to act as a communications server for other programs resident in an applications layer.

15. A computer programmed to create and encapsulate messages in an industry standard format, said computer further programmed to function as an Ethernet server for transmission of the messages.

16. A computer according to claim 15 further programmed to encapsulate messages with a TCP/IP Ethernet header and footer.

17. An Ethernet gateway comprising a programmable hardware device configured to:

receive Ethernet messages from an Ethernet server in an industry standard format;

remove both an Ethernet header and footer from the received Ethernet messages, leaving a message for transmission to at least one intelligent end device (IED); and

transmit the messages to the at least one IED.

18. An Ethernet gateway according to claim 17 wherein the Ethernet header and footer are in a TCP/IP format.

19. An Ethernet gateway according to claim 17 wherein said programmable hardware device is further programmed to receive messages from intelligent end devices.

20. An Ethernet gateway according to claim 19 wherein said programmable hardware device is further programmed to:

encapsulate received messages with an Ethernet header and footer; and

transmit the encapsulated messages to an Ethernet server.

21. An Ethernet gateway according to claim 20 wherein the messages are encapsulated with a TCP/IP header and footer.
