Draft IEC TR 61850-90-18 on Alarm Handling Published

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."

Navigation Light System for Offshore Wind Farms managed by IEC 61850

The Sabik NavAid Controller is part of the control and monitoring system for the marking of offshore wind
farms. It is used for controlling and monitoring of illuminating and marking components on
offshore structures:

• Activation and generation of the flash code for all of the attached 5 nautical miles lanterns
• Activation and generation of an intensity control signal for spotlights
• Current consumption monitoring for all components of the navigation light system, as well as error
  detection and reporting

The communication supports Modbus and IEC 61850.

The Sabik Logo is enhanced by the slogan: WE SHOW THE WAY … with the application of IEC 61850 (IEC 61400-25) Sabic shows also the way how to apply IEC 61850 for many applications outside substations.
