Hardback. Condición: New. Distribution systems analysis employs a set of techniques that allow engineers to simulate, analyse, and optimise power distribution systems. Combined with automation, these techniques underpin the emerging concept of the 'smart grid', a digitally-enabled electrical supply grid that can monitor and respond to the behaviour of all its components in real time. Distribution System Analysis and Automation provides a comprehensive guide to these techniques, with coverage including smart grid for distribution systems; introduction to distribution automation; network and radial load flow analysis; determination of the optimal topology for power electric systems; voltage VAR control and capacitor application; power quality and harmonics in distribution systems; harmonic filter design; distributionsystem restoration; short circuit analysis; arc flash concepts; numerical relaying and feeder protection; communication and control centres; and distributed energy resources. The book combines theoretical concepts with real-world applications, and includes MATLAB exercises.…

Hardback. Condición: New. 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.…

Hardback. Condición: New. High quality electrical service is key to power systems around the world, particularly in utilities and industrial facilities. Both voltage and grid frequency must be kept within tight limits to maintain functioning of critical infrastructure. The growing use of renewable power of intermittent character is adding to that challenge. One of the keys to achieving quality service is the protection system, which needs to be reliable, fast and with a good cost/benefit ratio. It consists of various components, including relays, circuit breakers and fuses. An understanding of the different behaviours of these components in the face of malfunctions, and of countermeasures, is needed. This book has established itself as a classic work in its field, allowing the reader to easily follow the ideas explored. It provides an overview of most aspects of electrical protections, with emphasis on distribution systems; but protection of generation and transmission systems are also addressed. For this 4th edition, new topics have been added, such as protection of renewable power plants and transient stability analysis. It offers a thorough revision of the material, particularly the numerical type of relays, protective functions, control, measurement, communications and oscillography features. Most chapters have illustrative examples using MATLAB or PSAT (Power System Analysis Tools). This work remains essential reading for researchers, utility engineers, design, maintenance and consulting engineers as well as for instructors and senior students.…
