The IEC 61850 standard originally was developed for the substation automation. During the past years it was adapted for the integration of distributed energy resources into communication networks, however, with specific requirements. Many small and midsize manufacturers are using, as controllers, a big variety of different microprocessors with limited performances. Such controllers need an inte...

IEC 61850-9-2 is an international substation automation standard that proposes a Process Bus communication network between process level equipment and bay level Intelligent Electronic Devices (IEDs) used for power systems protection and control. This paper considers the drive towards the use of IEC 61850-9-2 Process Bus in substations. The impact of the IEC 61850-9-2 standard on the operating p...

This paper presents a novel Loss of Mains (LoM) protection method based on IEC 61850 Manufacturing Messages Specification (MMS) protocol over wireless Global System for Mobile Communication (GSM) based access point name (APN) mechanism. LoM or anti-islanding protection is a key requirement in modern power distribution grids where there is significant amount of distributed energy resources (DER)...

according to IEC 61850 Klaus-Peter Brand, Wolfgang Wimmer Switzerland Summary The standard IEC 61850 „Communication Networks and Systems in Substations“ will provide interoperability for all functions in substations. To realize interoperable devices their data and functions have to be modeled according to IEC 61850. The approach and the data model of the standard is the key for understanding, b...

Within this contribution, we outline the use of the new automation standards family OPC Unified Architecture (IEC 62541) in scope with the IEC 61850 field automation standard. The IEC 61850 provides both an abstract data model and an abstract communication interface. Different technology mappings to implement the model exist. With the upcoming OPC UA, a new communication model to implement abst...

—With the development of intelligent substation in China, it becoming more important that the conformance testing of IEC 61850 is used to guarantee the interoperability between intelligent electric devices. In view of the current intelligent substation IEC 61850 conformance testing did not form a closed loop, which led to the lacking of comprehensiveness and integrity, a closed-loop conformanc...

The IEC 61850-advanced smart transformer shows an improved performance in monitoring, controlling, and protecting the devices and equipment in smart substation. However, the heterogeneity, feasibility and network control problems have limited smart transformers in network performance. To address these issues, a software-defined networking model is proposed using ISO/IEC/IEEE 21451 networks. The...

This paper describes how the new international standard series IEC 61850 is applied and extended to meet the requirements for almost the whole electrical energy supply chain, especially outside substations. Several activities are under way in the domains of power generation (wind power plants, hydro power plants, and decentralized energy resources), power transmission and distribution as well a...
