Power quality in power systems and electrical machines

The second edition covers power quality issues including new discussions related to renewable energy systems. Topics include: background on causes, effects, standards, and measurements of power quality and harmonics; harmonic modeling of power systems, including components and apparatus (electric machines); power quality mitigation approaches and devices; analysis of 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. It 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. --
