Protection of Electricity Distribution Networks (Energy Engineering)

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.
