Power Quality in Power Systems and Electrical Machines

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. Includes application examples including SPICE, Mathematica, and MATLAB examples Power Quality in Power Systems and Electrical Machines provides a comprehensive reference for understanding the causes, effects, modeling, measurement and resolution of power quality issues. This extensive volume covers power quality problems including nonsinusoidal wave shapes, voltage outages, harmonic losses, origins of single-time events such as voltage dips, voltage reductions and outages, along with techniques to mitigate these problems. Key Features: - Provides both theoretical and practical insight into power quality problems of machines and systems - Includes application examples implemented in SPICE, Mathematica and MATLAB - Numerous end-of-chapter problems - Analytical as well as measuring techniques are applied to power quality problems as they occur in existing systems - Provides extensive references (700+) - Suitable for use as an undergraduate/graduate course textbook as well as reference for professionals Power Quality in Power Systems and Electrical Machines, Second Edition helps readers understand the causes and effects of power quality problems and provides techniques to mitigate these problems. Power quality is a measure of deviations in supply systems and their components, and affects all connected electrical and electronic equipment, including computers, TV monitors, and lighting. In this book analytical and measuring techniques are applied to power quality problems as they occur in central power stations and distributed generation such as alternative power systems. Provides theoretical and practical insight into power quality problems; most books available are either geared to theory or practice only Problems and solutions at the end of each chapter dealing with practical applications Includes application examples implemented in SPICE, Mathematica, and MATLAB This book helps readers understand the causes and effects of power quality problems and provides techniques to mitigate these problems.
