The course is suitable for engineers, technicians, protection and control professionals, system integrators, automation engineers, commissioning engineers, and students.
Description

---

"This course contains the use of artificial intelligence."
Welcome to this comprehensive course onIEC 61850-7-4, designed to help electrical, protection, control, automation, communication, and substation professionals understand the standardized information model used in modern digital substations.
IEC 61850 is more than a communication protocol. It provides a structured approach for representing substation functions, equipment, measurements, protection functions, control functions, and status information so that different Intelligent Electronic Devices (IEDs) and automation systems can communicate and interoperate effectively.
In this course, you will develop a clear understanding ofIEC 61850-7-4, with particular focus onLogical Nodes, Data Objects, Data Attributes, Common Data Classes, and standardized functional models.
You will learn how real-world substation equipment and functions are represented within the IEC 61850 information model. The course connects the standard's concepts with practical applications in protection, control, measurement, monitoring, switching, and substation automation.
What You Will Learn

---

Throughout the course, you will learn
The purpose, scope, and importance of IEC 61850-7-4.
The fundamentals of the IEC 61850 information model.
The concept and structure ofLogical Nodes (LNs).
Logical Node naming conventions and functional classification.
The relationship between Logical Nodes, Data Objects, and Data Attributes.
The role ofCommon Data Classes (CDCs) in standardized information modeling.
How protection functions are represented using IEC 61850 Logical Nodes.
How measurement, control, monitoring, and switching functions are modeled.
Common Logical Nodes such asXCBR, XSWI, MMXU, PTOC, PDIS, TCTR, TVTR, CSWI, and CILO.
How physical substation equipment can be mapped to IEC 61850 functional models.
How standardized Logical Nodes support interoperability between IEDs from different manufacturers.
How IEC 61850-7-4 concepts are used in IED engineering and digital substation projects.
How to interpret Logical Node information in IEC 61850 documentation and configurations.
Practical Understanding
The course is designed to go beyond theoretical definitions. You will learn to look at a typical substation function and understandwhich IEC 61850 Logical Node can represent that function and what information is associated with it.
For example, you will explore how circuit breakers, disconnectors, current transformers, voltage transformers, protection functions, measurement functions, and control functions can be represented within the IEC 61850 information model.
This practical approach will help you understand the relationship betweenphysical equipment → substation function → Logical Node → Data Object → Data Attribute, providing a strong foundation for working with IEC 61850-based systems.
