Master's Degree Thesis Report Implementation of IEC 61499
Master’s Degree Thesis Report Karthik Gopinath Sharma [email protected] September 19, 2019 Implementation of IEC 61499 Applications for Centralized Power System Protection Platform SUPERVISORS Prof. Oriol Gomis Bellmunt(UPC) Tin Rabuzin (KTH) Escola Tecnica` Superior d’Enginyeria Industrial de Barcelona 1 Page No. 1 Acknowledgements To InnoEnergy Master’s School for giving me two years of free and superior edu- cation in the field of Smart Grids and Renewable Energy I could ever ask for. To UPC, Barcelona and KTH, Stockholm two of the finest universities along with the best professors and friends enabling me to enjoy the journey throughout my double master’s degree. To my supervisors, Oriol Gomis Bellmunt and Tin Rabuzin, for allowing me to pursue this project as part of my master thesis and being there with me throughout the dura- tion of the Master Thesis guiding me with their knowledge and experience. To Alois Zoitl, for taking his precious time out in helping me to understand a criti- cal issue during the project. To my family, for being my support always. Page No. 2 Abstract With the onset of distributed energy resources in the electricity generation, the sce- narios for protection and automation are becoming challenging. Even with guidelines like IEC61850 which focuses on digital substations there is a big issue in terms of inte- grating systems from different vendors. On the other hand IEC 61499 is moving ahead with enabling distributed automation and control in Industrial environment. This report aims to answer if it is possible to design an IED based on IEC61850 us- ing IEC61499. -

Smart Reconfiguration of Distribution Grids Using Agent-Based Technology
FACULDADE DE ENGENHARIA DA UNIVERSIDADE DO PORTO Smart Reconfiguration of Distribution Grids using Agent-based Technology Matheus Macedo Lopes Dissertation conducted under the Master’s in Electrical and Computers Engineering Program - Major Energy Supervisor: Prof. Vladimiro Miranda , Ph.D. Co-Supervisor: Prof. Diego Issicaba , Ph.D. July 28, 2016 © Matheus Macedo Lopes, 2016 Resumo As manobras de isolamento para reconfiguração em redes de distribuição de média tensão são tradicionalmente manuais ou dependem de decisões tomadas pelos operadores de rede. A abor- dagem proposta assume uma arquitetura onde os agentes interagem em um ambiente de rede de distribuição simulado a partir do estabelecimento de metas projetadas seguindo o paradigma de orientação mulit-agente. A aplicação é implementada de tal forma que agentes AgentSpeak in- teragem entre eles através de uma comunicação baseada em ato de fala/comunicação, bem como com um ambiente desenvolvido em linguagem JAVA. Neste contexto, esta tese propõe a modelagem e verificação de soluções baseadas em agentes para apoiar as operações de reconfiguração em redes de distribuição em nível de média tensão. A metodologia foi utilizada para apoiar as actividades dos operadores de redes de distribuição por meio de planos de restabelecimento de energia para ajudar em casos de falhas permanentes. As abordagens empregadas para arquitetura de agentes para a reconfiguração foram baseadas em modelo hierárquico e uma abordagem totalmente descentralizada. A capabilidade dos agentes foram desenvolvidas prevendo as possiveis aplicações do sistema de distribuição com foco em procedimentos de gestão des interrupções de service. As abordagens foram testadas em um ali- mentador teste trifásico do IEEE de 123 nós. -
Response Time for IEC 61499 Over Ethernet
Response Time for IEC 61499 over Ethernet Per Lindgren, Johan Eriksson, Marcus Lindner and Andreas Lindner David Pereira and Luís Miguel Pinho Luleå University of Technology CISTER / INESC TEC, ISEP Email:{per.lindgren, johan.eriksson, marcus.lindner, andreas.lindner}@ltu.se Email: {dmrpe, lmp}@isep.ipp.pt Abstract—The IEC 61499 standard provides means to specify general purpose usage. Our results are safe to the worst case, distributed control systems in terms of function blocks. The while further improvements can be obtained if the Maximum execution model is event driven (asynchronous), where triggering Transmission Unit (MTU) of general purpose (best effort events may be associated with data (and seen as a message). traffic) is controlled. In this paper we propose a low complexity implementation technique allowing to assess end-to-end response time of event We can conclude that the presented approach reduces chains spanning over a set of networked devices. In this paper we complexity of distribution (in comparison to the traditional develop a method to provide safe end-to-end response time taking SCADA approach), reduces device and network complexity both intra- and inter-device delivery delays into account. As a (does neither require complex time triggered architectures use case we study the implementation onto (single-core) ARM- like scan based PLCs, nor any dedicated network compo- cortex based devices communicating over a switched Ethernet network. For the analysis we define a generic switch model and nents/protocols), and is highly flexible (allowing network shar- an experimental setup allowing us to study the impact of network ing between real-time and best-effort devices). -

Calqrp Analog Power Meter Assembly Guide John Sutter W1JDS [email protected]
CalQRP Analog Power Meter Assembly Guide John Sutter W1JDS [email protected] Rev 1.1 August 7, 2018 About 3 weeks ago Doug Hendricks, KI6DS, mentioned he had a club project idea. I think he said he had some low cost meters and thought it would be good to spin an old project, the Christmas Power Meter, using the latest/greatest tools of the day which I’m sure will be laughable in another decade. That earlier project by apparently had the same instigator. Like the original by Song Kang, WA3AYQ and Bob Okas, W3CD, this version of the meter has two ranges, 1W and 10W using a SPDT switch to select between them instead of 2 BNC connectors. Beyond that, the schematic is pretty much the same. The tools I used: Schematic Capture KiCAD PCB Layout KiCAD PCB Fabrication AllPCB Enclosure Design OpenSCAD 3D Printer Creality CR-10 1 The Circuit As mentioned earlier the schematic matches the Christmas Power Meter pretty closely. SW1 is used to switch the power from the BNC connector into either the 10W load consisting of four 200 Ω 3 Watt carbon film resistors or the 1W load consisting of two 100 Ω ½ Watt carbon film resistors. The diodes are used as detectors with the resulting voltage filtered by the capacitors. The resistors are used to adjust the full-scale current to 200 μA. More on that later. FIGURE 1 SCHEMATIC A germanium diode was used on the 1 W range due to its lower voltage drop. More on that later. If you decide to use a through hole switch, the maximum shaft diameter is 6.3 mm. -

Portability of IEC 61499 Compliant Software
Portability of IEC 61499 compliant software Alexander Hopsu School of Electrical Engineering Master’s thesis Helsinki 21.1.2019 Supervisor Prof. Valeriy Vyatkin Advisor Dr Udayanto Atmojo Copyright © 2019 Alexander Hopsu Aalto University, P.O. BOX 11000, 00076 AALTO www.aalto.fi Abstract of the master’s thesis Author Alexander Hopsu Title Portability of IEC 61499 compliant software Degree programme Electronics and Electrical Engineering Major Control, Robotics and Autonomous Systems Code of major ELEC3025 Supervisor Prof. Valeriy Vyatkin Advisor Dr Udayanto Atmojo Date 21.1.2019 Number of pages 70+18 Language English Abstract This master’s thesis investigates the portability features of three different IEC 61499 standard compliant tools. Firstly, the thesis introduces the standard’s capabilities, then illustrates its use with a few example cases. The study continues by focusing on migrating the basic and composite function block types and system architecture with application networks and device configurations from one tool to another. A converter program is subsequently created using Python programming language to automate the required modification process, thus enabling the files to migrate between the compliant tools. The study takes into consideration NxtStudio, FBDK and 4DIAC software tools. In every tool, similar function blocks and system structures are created. The portability of these created elements is examined between the tools, resulting in a table that numerically evaluates the portability from one tool to another.
