What is IEC 61850-6 Ed2 2018?

IEC 61850-6 Ed2 2018 is a technical standard that specifies communication protocols for the automation of power systems. This international standard, developed by the International Electrotechnical Commission (IEC), provides guidelines for the exchange of information between intelligent electronic devices (IEDs) in substation automation and control systems.

The Purpose of IEC 61850-6 Ed2 2018

The primary purpose of IEC 61850-6 Ed2 2018 is to enable interoperability between different manufacturers' devices and systems within the electrical power domain. It sets out standardized methods for communication, allowing seamless integration of various components in substations and power systems, regardless of their origins or specifications.

By defining a common language and data model, IEC 61850-6 Ed2 2018 facilitates efficient information exchange among the multitude of IEDs deployed in power grid infrastructures worldwide. This interoperability is crucial for ensuring enhanced reliability, maintenance, and safety of power systems.

The Key Features and Benefits of IEC 61850-6 Ed2 2018

IEC 61850-6 Ed2 2018 incorporates several key features and benefits that make it an indispensable standard for power system automation. Firstly, it adopts a standardized object-oriented data model, known as the Substation Configuration Language (SCL), which simplifies device integration and system engineering. SCL provides a consistent framework for describing substation architectures, IED capabilities, and communication interfaces.

Another important feature of IEC 61850-6 Ed2 2018 is its support for various communication protocols, including Ethernet-based networks and the widely used TCP/IP stack. This versatility enables seamless integration with modern IT infrastructure and ensures future-proof compatibility with emerging technologies.

IEC 61850-6 Ed2 2018 also promotes the use of Sampled Values (SV) and Generic Object Oriented Substation Event (GOOSE) messaging, which enable fast and reliable exchange of real-time data within substations. These communication mechanisms enhance power system performance, enabling faster fault detection, isolation, and restoration processes.

Conclusion

In conclusion, IEC 61850-6 Ed2 2018 plays a vital role in advancing the automation and interoperability of power systems. By providing standardized communication protocols and data models, it enables seamless integration of IEDs from different manufacturers and ensures efficient information exchange. With its key features and benefits, this international standard facilitates reliable, safe, and future-ready power system automation, contributing to the overall stability and sustainability of the electrical grid.
