How Does IEC 61850-3 Apply for IEDs Outside Substations?

I have been contacted several times on the question: “What are the requirements in IEC 61850-3 (General requirements, EMC, EMI, …) that have to be applied in DER, SA, … Wind turbines, Hydro Power stations?”

In IEC 61850-3 these applications are partly excluded (57/1246/CDV) says under

6.7.1 Electromagnetic environment

“… In addition to the mentioned electrical plants, Electricity Utilities can install apparatus in

control centers, radio repeaters, or low voltage distribution points in industrial, commercial or residential areas. These locations are covered by other generic standards or product standards. …”

An IED for a Hydro power plant, PV inverter, other DER or DA application to become compliant with IEC 61850-3 requires some definition in IEC 61850-3 for these domains. Pointing to “other standards” is to fuzzy.

I would highly appreciate to get your opinion which most crucial standards for other areas than HV/MV substations are applicable. We could then summarize the result and publish some guidelines … hints.

Please contact me in case you have some useful hints on the applicability of IEC 61850-3 outside substations.
