Abstract

A method is disclosed for configuring an intelligent electronic device (IED) that includes enabling dynamic capability of the IED by a flexible data modeling technique to dynamically adapt a data model based on an application requirement using a configuration tool. A substation automation system is also disclosed which includes a local system equipment having a plurality of IEDs associated with the local system equipment and an IED configuration tool configured to interact with the firmware of each IED to configure the IED based on application requirements. The application configuration tool can include dynamic capability information of the IED to enable a flexible data model in the IED.

First claim

We claim:

1. A method for configuring an intelligent electronic device (TED), the method comprising:
in a processor of the IED:
executing a flexible data modeling technique to dynamically adapt a data model based on one of an application output and a physical field input,
wherein the flexible data model technique comprises:
pre-creating a data structure for the plurality of data objects in a configuration tool environment and in firmware, wherein the data structure includes the one or more common data classes and corresponding short address fields;
creating a requisite number of data object instances for the plurality of data objects based on the dynamic capability of the IED;
generating a generic data model using the requisite number of data objects instances;
assigning a logical node class in the configuration tool environment based on the one of the application output and the physical field input; and
dynamically creating a requisite number of logical node instances corresponding to the logical node class using the plurality of data objects, wherein a logical node comprises the corresponding short address fields for the plurality of data objects corresponding to the logical node class.

2. The method of claim 1 , wherein the flexible data modeling technique comprises:
supporting the one or more common data classes dynamically in the IED by using one or more digital/binary, or analog inputs as the physical field inputs for the plurality of data objects.

3. The method of claim 1 , wherein the flexible data modeling technique comprises:
dynamically creating a plurality of logical node instances for one or more logical node classes with the plurality of data objects.

4. The method of claim 3 , wherein the plurality of logical node instances comprise:
a varying number of data objects that are configured dynamically based on a predefined data object type information according to one of the application output and the physical field input.

5. The method of claim 1 , wherein the flexible data modeling technique comprises:
pre-creating a generic data model template in a configuration tool environment and in firmware based on a dynamic capability of the IED;
assigning a logical node class based on one of the application output and the physical field input; and
dynamically creating a requisite number of logical node instances based on logical node type information from the generic data model template to build an adaptive data model.

6. A substation automation system comprising:
local system equipment;
a plurality of intelligent electronic devices (IEDs) associated with the local system equipment, wherein each of the plurality of IEDs comprises firmware for providing a dynamic capability in the IED; and
an IED configuration tool configured to interact with the firmware of each IED to configure the IED based on one of an application output and a physical field input, the application configuration tool having dynamic capability information for configuring the IED to execute a flexible data model including the steps of:
pre-creating a data structure for the plurality of data objects in a configuration tool environment and in firmware, wherein the data structure includes the one or more common data classes and corresponding short address fields;
creating a requisite number of data object instances for the plurality of data objects based on the dynamic capability of the IED;
generating a generic data model using the requisite number of data objects instances;
assigning a logical node class in the configuration tool environment based on the one of the application output and the physical field input; and
dynamically creating a requisite number of logical node instances corresponding to the logical node class using the plurality of data objects, wherein a logical node comprises the corresponding short address fields for the plurality of data objects corresponding to the logical node class.

7. The substation automation system of claim 6 , wherein each of the plurality of IEDs is configured to execute the flexible data model to dynamically create a plurality of logical node instances for one or more logical node classes of the IED with a plurality of data objects.

8. The method of claim 5 , wherein the generic data model template is an IEC 61850 data model template.
