IEC 61850-90-11 - Modelling of Logics for IEC 61850 Based Applications

IEC TC 57 just published a 50+ page proposal for a very interesting topic:


Proposed IEC TR 61850-90-11, Communication networks and systems for power utility automation – Part 90-11: Methodologies for modelling of logics for IEC 61850 based applications

Comments to this draft are expected by 2018-07-27 at the latest.

This is likely the first time where application modelling (using a single configuration language!) integrates basic logic functions like AND, OR, Timer, ... including a Mapping of IEC 61850 data types and IEC 61131-3 / PLC Open XML data types.

The document introduces a couple of use cases describing mainly the control and monitoring of switchgears and electrical measurements.

Use case 1 – Busbar disconnector coupled in a double busbar arrangement
Use case 2 – Delayed breaker trip and blocking after 1st low gas pressure alarm
Use case 3 – Bay connected to busbar A
Use case 4 – Definite trip
Use case 5 – "Direct transfer open operation"
Use case 6 – Line outage detection in a breaker and a half scheme
Use case 7 – Unit trip logic
Use case 8 – Data quality management
Use case 9 – Switchgear control on the example of a busbar change-over

The modelling of logics could be of interest for many other applications.
