Abstract

A method, a substation automation apparatus and an intelligent electronic device (IED) are disclosed which are, for example, not limited only to publishing data (data emanating) from the IED. An exemplary method includes assigning a unique identifier to one or more data fields, where the one or more data fields is associated with a short address attribute in the data emanating from the intelligent electronic device; and dynamically updating the identifier based on user specific configuration data by an IED application configuration tool. The IED can include a list of functions; (e.g., each function being represented as a logical node; and each logical node containing data objects); and a flexible addressing scheme for configuring the data objects and publishing data from the IED, but not only data emanating from IED.

Claims

1. A method for publishing data emanating from an intelligent electronic device (IED), the method comprising:

assigning an identifier to at least one data field, wherein the at least one data field is associated with a short address attribute in the data emanating from the intelligent electronic device; and

dynamically updating the identifier based on user specific configuration data by an IED configuration tool, based on at least one of automatic configuration data from the IED configuration tool, and user specific configuration data, wherein the updated identifier is indicative of one or more properties of the at least one data object;

receiving IED configuration data from the IED configuration tool, wherein the IED configuration data includes configuration data associated with the at least one data object;

verifying the IED configuration data based on the updated identifier; and

publishing data of the intelligent electronic device, wherein the published data includes short address attribute having the updated identifier,

wherein the updated identifier is associated with at least one of a channel of a virtual output card in the IED, an Input/Output node of the IED, and a channel of an input board configured using the IED configuration tool.

2. The method of claim 1, wherein the dynamically updating is in response to virtual signals received from application logic of the intelligent electronic device.

3. The method of claim 1, wherein the identifier is associated with a position and a channel number of an Analog/Digital Input board, wherein the Analog/Digital Input board is configured using an IED configuration tool.

4. The method of claim 1, wherein the identifier is associated with a position and a channel number of an Analog/Digital Input board, wherein the Analog/Digital Input board is configured using an IED configuration tool.

5. The method of claim 2, wherein the identifier is associated with a position and a channel number of an Analog/Digital Input board, wherein the Analog/Digital Input board is configured using an IED configuration tool.

6. A substation automation apparatus for controlling and monitoring operations at a substation, comprising:

plural intelligent electronic devices (IEDs), each of the IEDs having a distinct capability, the distinct capability being represented as a list of functions, each function from the list of functions being represented as a logical node, each logical node containing at least one data object, wherein at least one data object employs a flexible addressing scheme for publishing data emanating from the IED, the flexible addressing scheme having an identifier assigned to the at least one data object for dynamic updating, wherein the at least one data object is associated with a short address attribute in data emanating from the IED; and

an IED configuration tool for configuring a subset of functions from the list of functions provided by each IED based on specifications of the substation, wherein the IED configuration tool is configured to dynamically update the at least one data object using the flexible addressing scheme based on at least one of automatic configuration data of the IED configuration tool and user specific configuration data, wherein dynamically updating the at least one data object includes updating the identifier which is indicative of one or more properties of the at least one data object, and wherein the identifier is associated with at least one of a channel of a virtual output card in a respective IED, an Input/Output (I/O) node of the respective IED, and a channel of an input board configured using the IED configuration tool,

wherein each IED is configured to receive IED configuration data from the IED configuration tool, verify the IED configuration data based on the updated identifier; and

publish data of the intelligent electronic device, wherein the IED configuration data includes configuration data associated with the at least one data object, AND wherein the published data includes the short address attribute having the updated identifier.

8. The substation automation apparatus of claim 6, wherein the dynamically updating is in response to virtual signals received from application logic of the intelligent electronic device.

7. An intelligent electronic device (IED) for monitoring and control of operations in a substation, the IED comprising:

a processor configured to include;

a list of functions, each function being represented as a logical node, each logical node representing at least one data object; and

a flexible addressing scheme for configuring the at least one data object from plural data objects and publishing data from the IED, based on an identifier assigned to the at least one data object, wherein the identifier is dynamically updated, each logical node is verified based on the updated identifier, and the at least one data object is associated with a short address attribute in data published from the IED,

wherein the identifier is associated with at least one of a channel of a virtual output card in the IED, an Input/Output (I/O) node of the IED, and a channel of an input board configured using an IED configuration tool, and

wherein the updated identifier is indicative of one or more properties of the at least one data object.

9. The IED of claim 7, wherein the dynamically updating is in response to virtual signals received from application logic of an intelligent electronic device.
