Sharing IEC 61850 Sampled Values

Sharing IEC 61850 Sampled Values

by Stefan Meier,  ABB Power Systems, Switzerland

The introduction of the IEC 61850 standard represents a great step forward in substation automation – and the process continues. One example is the application of the standard’s subsection, IEC 61850-9-2, for the sharing of sampled analog values using Ethernet.  By integrating this technology into substation automation systems in combination with non-conventional instrument transformers for current and voltage measurement with the latest communications technologies, it is now possible to connect primary (high-voltage) equipment to substation protection and control devices more effectively, improving the reliability, availability and safety of optimized substations.
