More than ninety case studies shed new light on power system phenomena and power system disturbances Based on the author's four decades of experience, this book enables readers to implement systems in order to monitor and perform comprehensive analyses of power system disturbances. Most importantly, readers will discover the latest strategies and techniques needed to detect and resolve problems that could lead to blackouts to ensure the smooth operation and reliability of any power system. Logically organized, Disturbance Analysis for Power Systems begins with an introduction to the power system disturbance analysis function and its implementation. The book then guides readers through the causes and modes of clearing of phase and ground faults occurring within power systems as well as power system phenomena and their impact on relay system performance. The next series of chapters presents more than ninety actual case studies that demonstrate how protection systems have performed in detecting and isolating power system disturbances in: Generators Transformers Overhead transmission lines Cable transmission line feeders Circuit breaker failures Throughout these case studies, actual digital fault recording (DFR) records, oscillograms, and numerical relay fault records are presented and analyzed to demonstrate why power system disturbances happen and how the sequence of events are deduced. The final chapter of the book is dedicated to practice problems, encouraging readers to apply what they've learned to perform their own system disturbance analyses. This book makes it possible for engineers, technicians, and power system operators to perform expert power system disturbance analyses using the latest tested and proven methods. Moreover, the book's many cases studies and practice problems make it ideal for students studying power systems.

Already much praised and described as ‘playful yet profound, Murakami-esque yet original…heartbreaking…stunning…an unforgettable debut’ (Vendela Vida), Atmospheric Disturbances is one of the most widely anticipated fiction debuts of 2008.‘Last December, a woman entered my apartment who looked exactly like my wife…’ Dr Leo Liebenstein is convinced that his wife has disappeared and that she has been replaced by a double.While everyone else may be fooled, Leo knows she cannot be his real wife, and sets off on a quixotic journey to reclaim his lost love. With the help of his psychiatric patient Harvey – who believes himself to be a secret agent who can control the weather – Leo attempts to unravel this mystery. Why has his wife been replaced? What do the secret workings of The Royal Society of Meteorology have to do with it? Who is the enigmatic Dr. Tzvi Gal-Chen, and is he, or maybe his wife, or perhaps even Harvey, at the center of it all? From the streets of New York to the southernmost reaches of Patagonia, Leo's erratic quest ultimately becomes a test of how far he is willing to take his struggle against the uncontested truth he knows to be false.Atmospheric Disturbances is at once a moving love story, a dark comedy, a psychological thriller, and a deeply disturbing portrait of a fracturing mind. In this highly inventive debut, with tremendous compassion and dazzling literary sophistication, Rivka Galchen explores the mysterious nature of human relationships, and how we spend our lives trying to weather the storms of our own making.
