An open platform for rapid-prototyping protection and control schemes with IEC 61850
No full textCommunications is becoming increasingly important to the operation of protection and control schemes. Although offering many benefits, using standards-based communications, particularly IEC 61850, in the course of the research and development of novel schemes can be complex. This paper describes an open-source platform which enables the rapid prototyping of communications-enhanced schemes. The platform automatically generates the data model and communications code required for an intelligent electronic device to implement a publisher-subscriber generic object-oriented substation event and sampled-value messaging. The generated code is tailored to a particular system configuration description (SCD) file, and is therefore extremely efficient at runtime. It is shown here how a model-centric tool, such as the open-source Eclipse Modeling Framework, can be used to manage the complexity of the IEC 61850 standard, by providing a framework for validating SCD files and by automating parts of the code generation process. The flexibility and convenience of the platform are demonstrated through a prototype of a real-time, fast-acting load-shedding scheme for a low-voltage microgrid network. The platform is the first open-source implementation of IEC 61850 which is suitable for real-time applications, such as protection, and is therefore readily available for research and education
Standardization of power system protection settings using IEC 61850 for improved interoperability
No full textOne of the potential benefits of smart grid development is that data becomes more open and available for use by multiple applications. Many existing protection relays use proprietary formats for storing protection settings. This paper proposes to apply the IEC 61850 data model and System Configuration description Language (SCL), which are formally defined, to represent protection settings. Protection setting files in proprietary formats are parsed using rule-based reasoning, mapped to the IEC 61850 data model, and exported as SCL files. An important application of using SCL-based protection setting files is to achieve protection setting interoperability, which could bring multiple compelling benefits, such as significantly streamlining the IED configuration process and releasing utilities from being “locked in” to one particular vendor. For this purpose, this paper proposes a uniform configuration process for future IEDs. The challenges involved in the implementation of the proposed approach are discussed and possible solutions are presented
Translating proprietary protection setting data into standardized IEC 61850 format for protection setting validation
No full textFor smart grid development, one of the key expectations is that the data should be accessible to and readily interpreted by different applications. Presently, protection settings are represented using proprietary parameters and stored in various file formats. This makes it very difficult for computer applications to manipulate such data directly. This paper introduces a process that translates the proprietary protection setting data into IEC 61850 standardised format and saves the data as System Configuration description Language (SCL) files. A code generation process that allows rapid implementation of the translation process is proposed. Among various applications, the paper demonstrates how such a translation process and generated SCL files can facilitate the development of an intelligent system for protection setting error detection and validation
Architecture for automatically generating an efficient IEC 61850-based communications platform for rapid-prototyping of protection schemes
No full textAlthough offering many benefits, using IEC 61850 in the course of research and development of new protection schemes can be costly and time - consuming. This paper describes an approach for automatically generating the low - level communications code required for an Intelligent Electronic Device (IED) to provide protection functionality, specifically Generic Substation Event (GSE) and Sampled Value (SV) messaging. The platform is designed to be lightweight; only GSE and SV messages – crucial for protection – are implemented. The communications infrastructure will ensure that the required GSE and SV data are available to the subscribing Logical Nodes. Therefore, the system designer can focus on the design and implementation of the protection scheme, rather than the underlying communications infrastructure. The architecture leverages the Eclipse Modelling Framework to manage the complexity of the IEC 61850 standard; this is achieved by automating several aspects of the code generation process
characterization of the iec 61850 standard in electrical substations
No full textEste trabajo se centra en caracterizar el estándar IEC 61850, que se ha vuelto muy importante en la automatización, control y protección de las subestaciones eléctricas. La norma busca que diferentes equipos de distintas marcas puedan trabajar juntos sin problemas, además de ofrecer procedimientos claros para configurar y probar los dispositivos, y establecer estrategias de protección y seguridad. Todo esto se logra mediante modelos de datos basados en objetos, servicios abstractos (ACSI), esquemas de comunicación que usan los modos cliente-servidor (MMS), publicador-suscriptor (GOOSE y Samples Values), y el Lenguaje de Configuración de Subestaciones (SCL). Debido a que diferentes propietarios han creado sus propios sistemas y protocolos de control, surgieron problemas para que los equipos pudieran comunicarse entre sí. Por eso, se desarrolló el estándar IEC 61850, que ayuda a que dispositivos de distintas marcas puedan integrarse y ser compatibles. Sin embargo, esta norma presenta ciertos retos para entenderla completamente, especialmente al intentar interpretar sus conceptos, modelos y servicios. Este proyecto surge como una respuesta a esos desafíos, atendiendo la creciente necesidad de aprovechar al máximo los procesos y los beneficios que ofrece la norma IEC 61850. Comprender bien esta norma es fundamental para implementarla correctamente y sacar el mayor provecho en la automatización, control y protección de las subestaciones eléctricas.This work focuses on characterizing the IEC 61850 standard, which has become very important in the automation, control, and protection of electrical substations. The standard aims to enable different brands of equipment to work together seamlessly, in addition to offering clear procedures for configuring and testing devices, and establishing protection and security strategies. All of this is achieved through object-based data models, abstract services (ACSI), communication schemes that use client-server (MMS), publisher-subscriber (GOOSE and Samples Values) modes, and the Substation Configuration Language (SCL). Because different owners have created their own control systems and protocols, problems arose in getting equipment to communicate with each other. Therefore, the IEC 61850 standard was developed, which helps devices from different brands integrate and be compatible. However, this standard presents certain challenges to fully understand, especially when trying to interpret its concepts, models, and services. This project arises as a response to these challenges, addressing the growing need to take full advantage of the processes and benefits offered by the IEC 61850 standard. A thorough understanding of this standard is essential to implement it correctly and maximize its benefits in the automation, control, and protectionof electrical substations

Full text linkDetta examensarbete behandlar konfiguration och övervakning av en simulerad elstation. I DEMVE-labbet vid Technobothnia i Vasa undersöks och testas IEC 61850-kommunikation från skyddsreläer av olika tillverkare. En elstation bestående av varierande skyddsreläer ska kunna kommunicera över Ethernet till en övervakningsenhet genom ett gemensamt protokoll.
Arbetets syfte var att ta i bruk en ny elstation bestående av sex reläer, och skapa en fungerande processbild i övervakningsenheten COM600. Målet var att konfigurera reläerna och COM600 så de kommunicerade över IEC 61850, och sen skapa en processbild av elstationen i realtid. Därefter skulle en manual på elstationens IEC 61850-konfiguration skrivas.
Arbetet utfördes i sin helhet och resultatet var en fullt fungerande processbild och en manual som dokumenterar IEC 61850-konfigurationen. Yrkeshögskolan Novia kommer använda sig av resultatet i utbildningen och för att skapa ett MicroSCADA-system.This thesis is about configuration and supervision of a simulated substation. IEC 61850 communication between different relay manufacturers is researched and tested in the DEMVE laboratory at Technobothnia in Vaasa. A substation consisting of various protection relays should be able to communicate over Ethernet to a supervision device using a common protocol.
The purpose of this work was to launch a new substation consisting of six relays and to create a working HMI (Human-Machine Interface) for the supervision device COM600. The goal was to configure the relays and COM600 to handle communication over IEC 61850, and then create a real-time HMI for the substation. A manual on how to configure the substation for IEC 61850 was to be written afterwards.
The work was entirely completed and the result was a fully functioning HMI and a manual documenting the steps in the IEC 61850 configuration. The Novia University of Applied Sciences will use the result for education, and to create a MicroSCADA system

IEC 61850-standardin käyttö vesivoimalaitoksilla
Full text linkIEC 61850-standardi on VEOlla jo käytössä sähköasemilla. Nyt haluttiin selvittää sen soveltuvuutta myös vesivoimalaitoksille. Tätä varten oli oleellista selvittää standardin erityiskohdat vesivoimaa varten. Tärkeänä pidettiin myös PLC:eiden, releiden ja muiden laitteiden liityntämahdollisuuksia standardin mukaiseen väylään. IEC 61850-standardin tavoite on mahdollistaa älykkäiden laitteiden välinen kommunikointi, vaikka laitteet olisivatkin eri laitevalmistajilta. Standardi tekee tämän jakamalla funktiot osiin, LN:iksi, ja kuvailemalla nämä osat mahdollisimman geneerisesti. Tietoa hankittiin ensin itse standardista, minkä jälkeen siirryttiin etsimään mahdollisia liityntätapoja IEC 61850-väylään laitevalmistajien esitteistä ja manuaaleista. Standardi on tehty toimimaan myös mahdollisilla tulevaisuuden kommunikaatiomenetelmillä, mikä tekee siitä turvallisen sijoituksen. Releiden kanssa standardi toimii lähes poikkeuksetta, mutta PLC:eiden, magnetointijärjestelmien ja turbiinisäädinten valmistajat eivät ole hypänneet mukaan yhtä innokkaasti. Kaikista näistä silti löytyy ainakin jokin tuote, jonka voi liittää IEC 61850-standardin mukaiseen väylään. Vesivoimaa varten standardi sisältää LN:t vesivoimalaitoksissa esiintyviä asioita varten.The client of the thesis VEO already applies the IEC 61850–standard in substa-tions. The purpose of this thesis was to find out if it should also be used in hydro-power plants. For this it was essential to study the parts of the standard especially concern hydropower. It was also important to find out whether PLCs, protection relays and other devices could be connected to the IEC 61850 bus. The point of the IEC 61850 is to allow IEDs to communicate with each other, even if the IEDs are made by different manufacturers. The standard does this by dividing functions into parts (LN) and then describing those parts in a generic way. Information was first gathered from the standard itself and later from manu-als and brochures of the manufacturers of the IEDs. One of the objectives of the standard was to make it future-proof, which makes using the standard a relatively safe investment. Relays are almost always made to accommodate the standard, but with PLCs, excitation systems and turbine gover-nors this is not always the case. Still, there are devices of each type that support the standard
