Harmonics and Power Systems (Google eBook)
Harmonics have always been a problem with industrial loads, but now more and more consumer and commercial power loads are cropping up as sources of harmonic currents. Approaching the problem from both utility and end-user perspectives, Harmonics and Power Systems addresses the most relevant aspects in the generation and propagation of harmonic currents in electrical networks.
Grounded in years of practical experience working and teaching in the electric, oil, and steel industries in several countries to address the harmonics problem, De La Rosa elucidates the concepts and equations with worked examples and various illustrations generated using current industrial software tools. From a general overview of the principles and equations used to describe and analyze harmonic currents to the fundamentals of power losses in harmonic environments, this field-tested book offers detailed coverage of passive harmonic filters, harmonic propagation analysis, and alternatives to filtering. The author provides a clear-cut procedure for evaluating harmonic current propagation and assessing their penetration into electrical networks. He also discusses the most important and widely used industry standards to control harmonic distortion levels.
Recognizing the diversity of power networks, this book examines the role of specific characteristics of various types of networks. Harmonics and Power Systems is an easy-to-follow, practical introduction for novices and a useful problem-solving tool for seasoned professionals.
