IEC TC 57 just published a new 50 page draft part of IEC 61850 (57/2157/DC):
IEC Draft TR 61850-90-18
Communication networks and systems for power utility automation –
Part 90-18: Alarm handling in IEC 61850 based systems
Comments are expected by Nov 29, 2019.
Work is done by TC 57/WG 10 together with TC 88/JWG 25 (Wind Turbines).
This part defines a methodology to handle alarms. The crucial concept is defining an “Alarm Server”.
Use-cases considered are related to:
WG 10: IED communications & associated data models in power systems
WG 17: Distributed Energy Resources
WG 18: Hydroelectric power plants
JWG 25: Wind Power
Sample Use case: Wind power system
"Several clients connected either to an alarm concentrator handling alarms from a system of
identical distributed IED’s or directly to one specific IED. Some of the alarms are defined as
latched and all alarms are defined either with or without acknowledgement.
If a wind turbine is maintained and thus in service state, all alarms must still be captured and
exposed, but marked with an “in-service” flag for filtering (and not to be annunciated).
The IED’s may either be proprietary devices or comply with IEC 61850.
Domain: Common in wind-power domains."
