A practical approach to IEC 61850 standard for automation, protection and control of substations

This article discusses the new IEC61850 Standard for Substation Automation, considering its functionalities, requirements, and definitions. It provides an application-oriented approach through the capabilities that the new tools and Intelligent Electronic Devices (IEDs) allow. The work highlights the importance of modern IEDs, emphasizing the main characteristics that these components must possess to meet the requirements of IEC 61850. Based on the new possibilities that the development of the norm has brought, the work presents the potential functionalities discussed in recent articles in the main events of the community, and highlights how to perform these tasks and use the resources now available. Through the implementation of Logical Nodes (LNs), GOOSE messages (Generic Object-Oriented Substation Event) and other tools, the authors approach the logical schemes of interlocking, and transfers or locks execution. All features, functionalities and data presented in the article are based on results obtained in a real application from the 110/ 20kV Babadag 1 Wind Farm.
