IEC 61850-7-410 Edition 2 is out for ballot

IEC 61850-7-410 Edition 2:
Communication networks and systems for power utility automation –
Part 7-410: Basic communication structure – Hydroelectric power plants –
Communication for monitoring and control

has been published for final ballot until 2012-10-05.

Changes in Edition 2 :

• Generic logical nodes in IEC 61850-7-410 Edition 1 that are not specific to hydropower plants have been moved to IEC 61850-7-4 Edition 2.
• The definitions of logical nodes have been cleaned up.
• Most of the modeling examples and background information has been moved to IEC/TR 61850-7-510 Edition 1 (see example below).
• New general-purpose logical nodes that are not included in IEC 61850-7-4 Edition 2, have been defined.

IEC 61850-7-410 Edition 2 defines 46 Logical Node classes and several hundred data objects:

IEC 61850-90-13 – New Work on IEC 61850 for Steam and Gas Turbines

The new work item has been introduced in the work programme under the title:
IEC 61850-90-13 Ed.1 (57/1259/RVN):
Communication networks and systems for power utility automation –
Part 90-13: Extension of IEC 61850 information models to also include logical nodes and data models for steam and gas turbines

IEC 61850 defines very common concepts, information models, services and configuration language that can be used in many other application domains outside substations. MMS – as a basic communication service to which IEC 61850 models and services are mapped – was originally defined for the manufacturing floor (MMS – Manufacturing Message Specification). So it is no surprise that it can be used there and in many other application domains.

One key issue in power plants is the RDS PP (related to KKS):

 

Examples of RDS PP for Wind Power Plants and IEC 61400-25/61850:

Binding of Information Models:

 

Examples from IEC 61850-7-510 (Hydroelectric power plants – Modelling concepts and guidelines):

Step by step we learn that IEC 61850 is in harmony with many other designation standards … and it can be used for almost all online (runtime) information exchange and system and IED configuration.
