The aim of this paper is to provide a concept for an information modeling method for micro grids, which will be used as building blocks for a smart grid. The data modeling method utilized is based primarily upon the IEC 61850 communication protocol standard. The article points out several useful features of the IEC 61850 communication protocol, the virtual information model and the communicatio...

This paper evaluates the Total Vector Error of an estimated Phasor as define in IEEE C37.118 standard within different medium access in Local Area Networks (LAN). Three different LAN models (CSMA/CD, CSMA/AMP and Switched Ethernet) are evaluated. The Total Vector Error of the estimated Phasor has been evaluated for the effect of Nodes Number under the standardized network Band-width values defi...

Using IEC 61850 standard would increase the reliability and availability of electricity network and put a huge impact on network automation. Even though much research works has been done in substation system reliability, there is a few works in automated substation control system reliability. This paper evaluates the reliability of substation automation system based IEC 61850 comparatively cons...

Replacing hardwired connections with digital communications over Ethernet requires new engineering and testing practices. PPL Electric Utilities Corporation (PPL) recently designed, installed, and tested a new high-voltage substation using next-generation relay and control equipment. This next-generation substation (NGS) is based on networked Ethernet intelligent electronic devices (IEDs) commu...

The so called Smart Grid is said to be distributed in nature with an accompanying control architecture which is made up of a heterogeneous network of controllers communicating in a peer-to-peer manner. The paper proposes a novel computer-aided model-based system engineering process for the design of a Smart Grid applications from the initial design specification through to the validation of the...

The ISO/IEC 61850 protocol for substation automation is a key component for the safe and efficient operation of smart grids, whilst offering a substantial range of functions. While extension standards, particularly ISO/IEC 62351 provide further security controls, the baseline protocol offers the assurances of access control and availability. In this paper a systematic study of selected aspects ...

This paper presents a study concerning the implementation of the 61850 standards (TCP/IP based standards for electric substations). The integration of communication networks in critical or safety applications is nowadays a strategic research problem. The approach consists of the proposition of new architectures according to the new standard IEC 61850. We also present the development of new devi...

The source maintenance technology of the smart substation offers the base for the models, data and graphs sharing between the substation and the dispatch center. This paper researches on the conversion technology between SCD model in IEC 61850 Ed. 2 and the CIM model in IEC 61970. The substation provides SVG and SCD documents to the dispatch center, which includes primary equipment information ...

The IEC 61850 Standard, Communications Networks and Systems in Substations, provides an internationally recognized method of local and wide area data communications for substation and system-wide protective relaying, integration, control, monitoring, metering, and testing. It has built-in capability for high-speed control and data sharing over the communications network, eliminating most dedica...

This document describes a development process of an offshore wind ontology based on the IEC 61400-25 standard. The methodology “METHONDOLOGY” and Protégé are used to build the ontology. Introduction Organizational units and information technology systems rarely last more than a few years. Only some parts of the data from these systems are used for decades and become one of the main assets. Obvi...
