Protection of Electricity Distribution Networks
This book provides an overview of most aspects of electrical protections. The emphasis is on distribution systems, but protection of generation and transmission systems are also treated. For this 4th edition, new topics are added, such as protection of renewable power plants and transient stability analysis.
Protection of Electricity Distribution Networks, 2nd Edition
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.
Distribution Systems Analysis and Automation
Distribution systems analysis employs a set of techniques to simulate, analyse, and optimise power distribution systems. Combined with automation, these techniques underpin the concept of the smart grid. In recent years, distribution systems have been facing growing challenges, due to increasing demand as well as the rising shares of distributed and volatile renewable energy sources. For this new edition, the chapters of the first edition have been revised and updated, and the topics of distribution system analysis and distribution automation combined. Coverage includes smart grid, load flow analysis, determination of optimal topology, voltage control and capacitor application, power quality and harmonics in distribution systems, distribution system restoration, numerical relaying and distribution feeder protection, distributed generation and microgrid technology. New material related to renewable energy and microgrids are included, and maturity models and evaluation of smart grid projects are presented, along with material on the transition to the new distribution system technologies.
Protection of Electricity Distribution Networks
This revised and updated edition introduces references to modern topics such as Distributed Generation, Smart Grid and Standard IEC 61850.
Protection of Electricity Distribution Networks
Descripción del editor: "High quality electrical service is everyday more stringent in utilities and industrial facilities around the world. One of the main players to achieve this is the protection system, which has to be reliable, fast and with a good cost/benefit ratio. Protection of generation and transmission systems are also treated in the text. References to modern topics such as the Distributed Generation, Smart Grid and Standard IEC 61850 have been introduced. Written by two well experienced engineers who combine a comprehensive theoretical background with examples and exercises, this book will allow the reader to easily follow the ideas explored." (IET).
Distribution Systems Analysis and Automation
Distribution systems analysis uses techniques to simulate, analyse, and optimise power distribution systems. Together with automation, these techniques underpin the smart grid. Distribution systems are facing growing challenges, due to increasing demand as well as the rising shares of distributed and volatile renewable energy sources.
Protection of Industrial Power Systems
The protection which is installed on an industrial power system is likely to be subjected to more difficult conditions than the protection on any other kind of power system. Starting with the many simple devices which are employed and covering the whole area of industrial power system protection, this book aims to help achieve a thorough understanding of the protection necessary. vital aspects such as the modern cartridge fuse, types of relays, and the role of the current transformer are covered and the widely used inverse definite-minimum time overcurrent relay, the theory of the Merz-Price protection system and the development of the high-impedance relay system are critically examined. This new edition has come about in response to the dramatic change from the use of electro-magnetic relays to electronic and micro-processor relays which figure in practically all new installations. Therefore, although the theory and usage are the same, the application can be much improved owing to the increased range and accuracy and the added facilities provided with the modern relays. This book reflects the change and explains the technical advantages.
The Collapse of Complex Societies
Dr Tainter describes nearly two dozen cases of collapse and reviews more than 2000 years of explanations. He then develops a new and far-reaching theory.
Juan Patron
"Juan Patrón lived through one of the bloodiest chapters of the American West: the 1878 feud known as the Lincoln County War in New Mexico. Reputed for his heroics, Patrón tried to tame a frontier plagued with violence, illiteracy and greed-first as a teacher, then as a desperado hunter, and eventually as speaker of the territorial house at age twenty-five, the youngest person to hold this position in New Mexico history. ... the author leads us through Patrón's life and times-and his fate at the hands of a Texas cowboy named Michael Maney, who outdrew him in a dramatic showdown. Many believe that, had he lived, Patrón would have become New Mexico's first congressman when it entered the Union in 1912"--Page 4 of cover.
