This book was released on 2012-11-25 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electric power delivery system that carries electricity from large central generators to customers could be severely damaged by a small number of well-informed attackers. The system is inherently vulnerable because transmission lines may span hundreds of miles, and many key facilities are unguarded. This vulnerability is exacerbated by the fact that the power grid, most of which was originally designed to meet the needs of individual vertically integrated utilities, is being used to move power between regions to support the needs of competitive markets for power generation. Primarily because of ambiguities introduced as a result of recent restricting the of the industry and cost pressures from consumers and regulators, investment to strengthen and upgrade the grid has lagged, with the result that many parts of the bulk high-voltage system are heavily stressed. Electric systems are not designed to withstand or quickly recover from damage inflicted simultaneously on multiple components. Such an attack could be carried out by knowledgeable attackers with little risk of detection or interdiction. Further well-planned and coordinated attacks by terrorists could leave the electric power system in a large region of the country at least partially disabled for a very long time. Although there are many examples of terrorist and military attacks on power systems elsewhere in the world, at the time of this study international terrorists have shown limited interest in attacking the U.S. power grid. However, that should not be a basis for complacency. Because all parts of the economy, as well as human health and welfare, depend on electricity, the results could be devastating. Terrorism and the Electric Power Delivery System focuses on measures that could make the power delivery system less vulnerable to attacks, restore power faster after an attack, and make critical services less vulnerable while the delivery of conventional electric power has been disrupted.
Download or read book Power Transmission System Analysis Against Faults and Attacks written by Tamalika Chowdhury and published by CRC Press. This book was released on 2021-04-12 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present-day power grid is basically a complex power transmission network with risks of failure due to unplanned attacks and contingencies, and therefore, assessment of vulnerability of transmission network is important and the process is based on contingency approach. This book deals with the methods of assessment of the grid network vulnerability and addresses the grid collapse problem due to cascaded failures of the transmission network following an attack or an unplanned contingency. Basic mitigation aspects for the network has been explored and the immunity of such a power transmission network against vulnerable collapse has been described using mathematical models.
Download or read book Real Time Stability in Power Systems written by Savu C. Savulescu and published by Springer Science & Business Media. This book was released on 2006 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the aftermath of the wave of blackouts that affected US, UK and mainland Europe utilities in 2003 and 2004, renewed attention has been focused on maintaining the highest level of reliability and security in the operation of power systems. The lack of adequate transmission infrastructure as well as real-time tools aimed at detecting and alarming system conditions have also been highlighted. In this context, the need to assess stability and predict the risk of blackout in real-time has become particularly relevant. Early work in this field documented in technical papers published throughout the 1990s and early 2000s underlined the importance of performing stability assessment in real-time. While static security assessment is conceptually straightforward, innovative approaches are needed to combine it with dynamic security assessment to develop an overall scheme so that results can be used for on-line decision-making. On October 13, 2004, the IEEE Power Systems Conference and Exposition 2004 hosted the ‘Real-Time Stability Challenge’ panel session. Organized by the Power System Dynamic Performance Committee, the panel was a forum for presenting progress achieved in this field, discussing new ideas, and identifying the challenges to be met in the course of future research. Real-Time Stability in Power Systems: Techniques for Early Detection of the Risk of Blackout is built around most of the panel papers, updated and expanded by the authors with the new material relevant to the panel theme. The chapters are contributed by well known experts in the field, thus providing an authoritative reference on the theory and implementation of real-time stability assessment -- one of the critical topics of the day. Some of the issues discussed in the book include, but are not limited to: *Stability limits and how to objectively define them, *Techniques for defining and measuring the distance to instability, *The characterization of the risk of blackout, *Discussion of quick, approximate methods to filter out non-critical contingencies and do a detailed simulation only of those that result in limit violations, *Theoretical description and practical experience with real-time and/or near real-time stability applications available today in the SCADA/EMS industry.

Available in PDF, EPUB and Kindle. Book excerpt: A falta de recursos e a questão ecológica têm limitado a expansão do sistema de transmissão. Esta realidade, em conjunto com o crescimento da carga, faz com que os sistemas elétricos trabalhem bastante carregados. Esta nova condição pode levar a situações de colapso de tensão. Métodos para avaliação do carregamento da rede de transmissão tornaram-se necessários e imprescindíveis para que se possa entender o funcionamento do sistema nestas condições e possibilitar a sua operação de modo correto. Ferramentas analíticas têm sido usadas para reforço das condições de segurança de tensão do sistema em tempo real, se for avaliado que o sistema não é suficientemente seguro. Ações operativas de controle são determinadas, para mover o estado do sistema para um ponto de operação seguro. Entretanto, ferramentas de avaliação e reforço não são a única necessidade. As mesmas ações de controle, que podem afastar o sistema de uma situação de instabilidade de tensão, também podem ter efeito oposto ao esperado e contribuir para o problema, podendo até mesmo levar o sistema ao colapso. Portanto, é necessário o desenvolvimento de uma ferramenta computacional para avaliara adequação de ações de controle de tensão. Neste trabalho é proposta uma ferramenta computacional, desenvolvida com base no sistema linearizado das equações de fluxo de carga, incluindo equações de controle de tensão e limites, para a avaliação do efeito das ações de controle de tensão. São obtidos índices que permitem avaliar se a ação de controle é adequada ou não. Além disso, esses índices podem avaliar a interdependência entre os controles, porque além deindicarem o efeito do controle sobre a tensão da barra controlada, podem indicar também o efeito do controle sobre as outras barras de tensão controlada do sistema. Estes índices podem ser obtidos de forma extremamente rápida, e são adequados para uso em tempo-real.

Download or read book Protection of Electricity Distribution Networks 2nd Edition written by Juan M. Gers and published by IET. This book was released on 2004 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by two practicing electrical engineers, this second edition of the bestselling Protection of Electricity Distribution Networks offers both practical and theoretical coverage of the technologies, from the classical electromechanical relays to the new numerical types, which protect equipment on networks and in electrical plants. A properly coordinated protection system is vital to ensure that an electricity distribution network can operate within preset requirements for safety for individual items of equipment, staff and public, and the network overall. Suitable and reliable equipment should be installed on all circuits and electrical equipment and to do this, protective relays are used to initiate the isolation of faulted sections of a network in order to maintain supplies elsewhere on the system. This then leads to an improved electricity service with better continuity and quality of supply.
