Power Quality in Power Systems and Electrical Machines, Second Edition

The second edition of this must-have reference covers power quality issues in four parts, including new discussions related to renewable energy systems. The first part of the book provides background on causes, effects, standards, and measurements of power quality and harmonics. Once the basics are established the authors move on to harmonic modeling of power systems, including components and apparatus (electric machines). The final part of the book is devoted to power quality mitigation approaches and devices, and the fourth part extends the analysis to power quality solutions for renewable energy systems. Throughout the book worked examples and exercises provide practical applications, and tables, charts, and graphs offer useful data for the modeling and analysis of power quality issues. Provides theoretical and practical insight into power quality problems of machines and systems, enabling the reader to solve the power quality problems that they encounter Worked examples and end of chapter exercises (with available solutions) show practical applications of the material discussed in the chapter New to this edition: identifies problems and solutions associated with renewable energy sources, provides more practical examples, and provides a website with downloadable examples using SPICE, Mathematica, and Matlab©

Power Quality of power systems affects all connected electrical and electronic equipment. Power Quality is a measure of deviations in voltage and frequency of the particular supply system. In recent years, there has been a considerable increase in nonlinear loads, in particular distributed loads, such as computers, TV monitors and lighting. These draw harmonic currents which, when distorted, have detrimental effects including interference, loss of reliability, increased operating costs, equipment overheating, motor failures, capacitor failure and inaccurate power metering. This subject is pertinent to engineers involved with electric power systems, electronic equipment, computers and manufacturing equipment. This book shows readers to understand the causes and effects of power quality problems such as non-sinusoidal wave shapes, voltage outages, losses due to poor power quality, origins of single-time events such as voltage dips, voltage reductions, and outages, along with techniques to mitigate these problems. . Provides theoretical and practical insight into power quality problems of machines and systems . Problems/solutions at the end of each chapter dealing with practical applications .
