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...

The Function Block (FB) model was first standardized by the 1131 standard of the International Electrotechnical Commission (IEC) for programmable controllers. This standard was successfully adopted by the industry but it seems to have several constraints for the development of today’s complex embedded control and automation systems. These constraints are mainly imposed by the procedural program...

Dynamic and adaptable integration of Distributed Energy Resources (DERs) into novel power system assets, such as microgrids, is one of the key prerequisites for accelerated Smart Grid deployment. By using standardized network interfaces and semantic descriptions for remotely controllable DERs, it is possible to develop intelligent microgrid applications capable of dealing with dynamic loads and...

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...

Many of the specific functions of intrinsically disordered protein segments are mediated by Short Linear Motifs (SLiMs) interacting with other proteins. Well known examples include SLiMs that interact with 14-3-3, PDZ, SH2, SH3, and WW domains but the true extent and diversity of SLiM-mediated interactions is largely unknown. Here, we attempt to expand our knowledge of human SLiMs by applying i...

The emerging International Standard ISO/IEC 15504 (Software Process Assessment) includes an exemplar assessment model (known as Part 5). Thus far, the majority of users of ISO/IEC 15504 employ the exemplar model as the basis for their assessments. This paper describes an empirical evaluation of the exemplar model. Questionnaire data was collected from the lead assessors of 57 assessments world-...

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)...
