Introduction

To understand the functioning and mode of operation of a substation in an IEC 61850 automation environment, it is

useful to compare the commissioning steps with those of a conventional substation in a Modbus TCP environment. In a

conventional substation, the individual Intelligent Electronic Devices (IEDs) communicate in a vertical direction with the

higher level control center via Communication. The horizontal communication is exclusively realized by wiring relay

outputs (RO) and digital inputs (DI) together.

In an IEC 61850 environment, communication between the IEDs takes place digitally (via Ethernet) by a service called

Generic Object Oriented Substation Event (GOOSE). By means of this service, information about events is submitted

between each IED. Therefore each IED has to know about the functional capability of all other connected IEDs.

Each IEC 61850 capable device includes a description of its own functionality and communications skills (IED

Capability Description, *.ICD). By means of a Substation Configuration Tool to describe the structure of the substation,

assignment of the devices to the primary technique, etc., virtual wiring of the IEDs between each other and with other

switch gear of the substation can be achieved. A description of the substation configuration will be generated in the

form of a *.SCD file. Finally, this file has to be submitted to each device. Now the IEDs are able to communicate with

each other, react to interlockings, and operate switch gear.
