The standard series IEC 61850 is applicable for simple applications and huge systems. The standard is not restricted to a specific domain. Like electric power is everywhere. So could IEC 61850 be everywhere.
I have discussed this briefly in the context of a LinkedIn post.
Now it's time to discuss briefly two simple applications ... just looking at the two models ... without further explanations.
The German FNN Steuerbox
The Steuerbox is mainly providing schedules for the interface between the grid and the power user:
This model is defined for a special use-case: Steuern (remote control). No need for an engineering tool ... it is just a fixed model ...
The Netherlands RTI (Real-Time Interface) for power generation (> 1 MW)
... this is a fixed model with some details:
The RTI models and services are currently using IEC 61850-8-1 (MMS) communication (RTI 1). The RTI 2 will finally use the IEC 61850-8-3 (DMS) once it is specified. A Task Force has started to specify the new standard in May 2026.
The fixed models allow for a high level of interoperability. The central systems (representing the IEC 61850 clients) can communicate with and IED following these specifications. In the case of the FNN Steuerbox it has been proven that the client application could talk to all steuerboxes in the field without paying attention to which vendors device it is talking to.
REAL INTEROPPERABILITY !!
