Practical IEC 61850 for Substation Automation for Engineers and Technicians

THE WORKSHOP

Older (‘legacy’) substation automation protocols and hardware/software architectures provided basic functionality for power system automation, and were designed to accommodate the technical limitations of the technologies available at the time. However, in recent years there have been vast improvements in technology, especially on the networking side. This has opened the door for dramatic improvements in the approach to power system automation in substations.

The latest developments in networking such as high-speed, deterministic, redundant Ethernet, as well as other technologies including TCP/IP, high-speed Wide Area Networks and high-performance embedded processors, are providing capabilities that could hardly be imagined when most legacy substation automation protocols were designed.

IEC61850 is a part of the International Electro-technical Commission (IEC) Technical Committee 57 (TC57) architecture for electric power systems. It is an important new international standard for substation automation, and it will have a significant impact on how electric power systems are designed and built in future. The model-driven approach of IEC61850 is an innovative approach and requires a new way of thinking about substation automation. This will result in significant improvements in the costs and performance of electric power systems.

This workshop provides comprehensive coverage of IEC 61850 and will provide you with the tools and knowledge to tackle your next substation automation project with confidence.
