„Lumpensammler“ in der Stationsautomatisierung mit IEC 61850 - Störmelder

EES (Backnang) bietet eine "super-einfache" Lösung zur Alarmierung von Störungen in IEC 61850 basierten Systemen:

"Neben den Informationen von Feld- und Schutzgeräten, fallen in Schaltanlagen zusätzliche Meldungen an, die an die Leittechnik übermittelt werden sollen. Diese Informationen sollen über die vorhandene Infrastruktur mit dem Protokoll IEC 61850 übertragen werden. ... 

1. Einbindung von Einzelmeldungen in die Stationsautomatisierung über IEC 61850
2. Integrierte Relaisausgänge zur Befehlsausgabe
3. Einfache Parametrierung über integrierten Web-Server
4. Zuverlässiger Betrieb durch störfestes Design und angepasste Signalverarbeitung
5. Hohe Funktionalität und Skalierbarkeit von 8 bis zu 192 Meldungen ..."

Dieses Beispiel zeigt, dass IEC 61850 auch für einfache Aufgaben angewendet werden kann!

„Rag-man“ in Substations Applying IEC 61850 - Fault Annunciators

EES (Backnang, Germany) offers a nice solution for simple and easy alarming in IEC 61850 based systems:

"In addition to the information provided by the field and protection devices over IEC 61850, different single alarms incurr in switchgear stations, e.g. from the station supply switchboard section or general alarms like temperature monitoring or door contacts. ... 

1. Simple integration of fault annunciators into IEC 61850 structures – through copper or optical fibre connection
2. Integrated relay outputs for issue of commands
3. Easy parameterisation through integrated web-server
4. Reliable operation through immune design and adapted signal processing
5. High functionality and scalability from 8 up to 192 alarms ..."

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."
