## Preface of Fundamentals of Electric Power Engineering by Isaak D. Mayergoyz and Patrick Mcavoy

The book consists of three parts. The first part of the book deals with the review of electric and magnetic circuits. This review stresses the topics which nowadays are usually deemphasized (or ignored) in required circuits and electromagnetics courses. Namely, the phasor diagrams for ac circuits and analysis of electric circuits with periodic non-sinusoidal sources are stressed. Phasor diagrams have practically disappeared from circuit courses and textbooks, while these diagrams are still very instrumental in electric power engineering. Analysis of electric circuits with periodic nonsinusoidal sources is very important in the study of steady-state operation of power electronics converters. The frequency-domain and time-domain techniques for such analysis are presented in the book.

In the review of magnetic circuits, a special emphasis is made on the analysis of magnetic circuits with permanent magnets. This is justified, on the one hand, by the proliferation of permanent magnets in power devices and, on the other hand, by the insufficient discussion of this topic in the existing undergraduate textbooks. Furthermore, the analysis of nonlinear magnetic circuits and eddy current losses for circularly (or elliptically) polarized magnetic fields are presented. The former is important because magnetic saturation of ferromagnetic cores often occurs in power devices. The latter is of interest because ferromagnetic cores of ac electric machines are subject to rotating (not linearly polarized) magnetic fields.

The second part of the book can be used for teaching courses on power systems and electrical machines. This part starts with a brief review of the structure of power systems, analysis of three-phase circuits and the discussion of ac power and power factor. Next, the analysis of faults in power systems is presented. This analysis is first performed by using the Thevenin theorem. Then, the concept of symmetrical components is introduced and the sequence networks are derived. Finally, the analysis of faults based on sequence networks is discussed. The next chapter deals with transformers. Here, the design and principle of operation of transformers are first considered along with the study of the ideal transformer.

Then, the equivalent circuit for a single-phase transformer is derived on the basis of equivalent mathematical transformation of coupled circuit equations and the importance of leakage inductances (leakage reactances) is stressed. Next, open-circuit and short-circuit tests are described as the experimental. means of determining parameters of equivalent circuits.

From the Back Cover of the book:

**Electric power engineering** has always been an integral part of electrical engineering education. Providing a unique alternative to existing books on the market, this compendium provides a concise and rigorous exposition of the main fundamentals of electric power engineering. Contained in a single volume, the materials can be used to teach three separate courses electrical machines, power system and power electronics, which are in the mainstream of the electrical engineering curriculum of most universities worldwide. The book also highlights an in-depth review of electric and magnetic circuit theory with emphasis on the topics which are most relevant to electric power engineering.
