Abstract

Automation system based on communication network, installed to provides facilities for on-site personnel to monitor/control/configure system and connect equipment required to test system. Can automate specific procedures for activities to eliminate human error. Provides necessary commands to the system, other devices and individual functions which enable/disable operation, change operating configuration or send/retrieve certain information. Independent of other devices which provide real time operation of the system to maintain safe and reliable operation of system whilst changes are being made to system regardless of operating condition of other devices. As an independent device to the system, can be standardized at a particular installation and across multiple installations to reduce personnel training and reduce possibilities of human error due to variability of features provided in other devices. Provides authorization facilities to permit activities by authorized operators or only permit communication to system of equipment connected to the device authorized to do so.

Claims

1-7. -7. (canceled)

8. An operator controlled interface unit configured to access and interact with a substation automation system or SAS, the SAS having:

an SAS network;

at least one intelligent electronic device or IED connected to and configured to communicate with the SAS network and having an at least first function; and

a user controlled interface connected to and configured to communicate with the SAS network, the user controlled interface being independent of the at least one IED.

2. The system of claim 8, wherein the SAS comprises an at least second function connected to the SAS network.

3. The system of claim 8 wherein the SAS is configured to utilize IEC 61850 mechanisms in order to send and receive messages via a LAN to provide information, signals, commands and responses to or from, or to and from, the at least one IED of the SAS.

4. The system of claim 8 wherein the at least one IED having the at least first function is IEC 61850 compliant.

5. The system of claim 8 wherein the user controlled interface is IEC 61850 compliant.

6. The system of claim 8 wherein the user controlled interface is configured to allow signals to be sent to or from the at least first function or detected as being sent to or from the at least first function and the response of the at least first function without necessarily taking any specific control, command or disruption of the at least first function, the at least one IED in which it is located or the SAS network.

7. The system of claim 8 wherein the user controlled interface is configured to accept a command to modify operation of the at least first function, the at least one IED or SAS to authorize a user to use controls integrated with an operator controlled interface unit;

authorize connection of other user'"'"'s equipment to communicate with the SAS;

connect to at least one network personal computer or other test equipment, or said at least one network personal computer and other test equipment, through communication ports via the operator controlled interface unit to enable interaction with the at least first function;

connect links, switches, indicators for the user to interact with the at least first function;

change a parameter of the at least first function to a different value;

enable or disable or modify a mode of operation of the at least first function or the IED, or the mode of operation of the at least first function and the IED;

enable or disable input to or outputs from, or inputs to and outputs from, the at least first function from the network;

observe that status or operation, or status and operation, of the at least first function;

observe or record or analyze, or observe and record and analyse messages, on the SAS network;

create signals on the SAS network to test operation of the at least first function or the SAS network itself, or the at least first function and the SAS network itself, using equipment connected by the user to the user controlled interface;

create signals on the SAS network to manage operation and performance of the at least second function whilst the user is undertaking activities associated with the at least first function.
