Communication networks and systems for power utility automation - Part 7-410: Basic communication structure - Hydroelectric power plants, steam and gas turbines - Logical node classes

IEC 61850-7-410:2026 specifies the logical node classes for use in the domain of hydroelectric power stations, steam and gas turbines.

This IEC61850 domain information model standard utilizes the existing Logical Node (LN) classes defined in IEC 61850-7-4, Basic communication structure – Compatible logical node classes and data object classes where possible, while defining new and extended domain specific LN classes to provide the necessary data objects for application to functions and systems in the domain of hydroelectric power stations, steam and gas turbines. The domain information model includes the interface towards a central operator centre’s control functions.

The Scope of this document, related to steam and gas turbine specifics, is limited to overall control functions and generator and turbine control functions. For hydroelectric power, the scope includes the entire power station automation system.

Edition 3 is intended to form a basis for extensions in local implementations. Such extensions may be defined in profiles. Many of the Logical Nodes defined in this document are designed to be suitable for use in domains beyond the scope of hydro power plants and steam and g
