IEC 61850 Integration of Substation Protection and Control – Test Facility

The IEC 61850 standard is intended to provide a standardised framework for the implementation of communication-based Substation Automation Systems (SAS). The principal benefits of employing the IEC 61850 approach are:

Reduced engineering through re-usable designs
Reduced time and cost for assembly and wiring
Reduced site wiring and installation
Increased off-line testing resulting in faster commissioning and reduced outage durations

Iberdrola’s early experiences of attempting to engineer an IEC61850 compliant multi-vendor substation using the various files and software tools from each vendor led to unsatisfactory conclusions:

It was difficult to achieve interoperability between devices from different vendors as each vendor has implemented the IEC 61850 standard according to its own designs. No two vendors implement the same functions to the same extent
The engineering process was complex and time consuming. It required extensive work to create the Intelligent Engineering Device (IED) configuration files and an expert knowledge of the underlying format of IEC 61850 configurations.

Benefits

This project will be deemed successful if the test centre becomes fully functional and the learning from the centre has been used to enable novel protection systems in transmission substations.
