Disturbance Analysis for Power Systems 

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.
