Abstract

The book is about one of the most controversial problems in electrical engineering: definitions of electric powers and compensation, discussed for more than a century. Several different approaches to the explanation of the power properties of electrical circuits and their compensation have occurred and a huge number of articles based on different approaches have been published. These approaches are referred to as “schools of power theory” (PT). The main power theories have been formulated by Budeanu, Fryze, Shepherd and Zakikhani, Kusters and Moore, as well as. There were also Hilbert Transform-based PT, Akagi’s Instantaneous Reactive Power p-q Theory, Czarnecki’s Currents’ Physical Components (CPC)-based PT, Depenbrock’s FDB Method, IEEE Standard 1459, and Tenti’s Conservative Power Theory (CPT). Some definitions of powers that were introduced within the framework of these schools were adopted by the IEEE, German Standards (DIN), and International Electrotechnical Commission (IEC) as standards. The development of the Currents’ Physical Components based power theory by the author of this book was a major contribution to this debate. It explains all power-related physical phenomena in electrical circuits and creates fundamentals for compensation in circuits of any complexity. The book explains power properties and compensation in electrical circuits just in terms of CPC-based PT. The book was written as a by-product of more than thirty years of the author’s teaching at Louisiana State University of undergraduate and graduate courses on powers and compensation. The book will be the leading reference for studies on powers in circuits with nonsinusoidal currents for numerous scholars involved in such studies.
