This book serves as a tool for any engineer who wants to learn about circuits, electrical machines and drives, power electronics, and power systems basics

From time to time, engineers find they need to brush up on certain fundamentals within electrical engineering. This clear and concise book is the ideal learning tool for them to quickly learn the basics or develop an understanding of newer topics.

Fundamentals of Electric Power Engineering: From Electromagnetics to Power Systems helps nonelectrical engineers amass power system information quickly by imparting tools and trade tricks for remembering basic concepts and grasping new developments. Created to provide more in-depth knowledge of fundamentals—rather than a broad range of applications only—this comprehensive and up-to-date book:

• Covers topics such as circuits, electrical machines and drives, power electronics, and power system basics as well as new generation technologies
• Allows nonelectrical engineers to build their electrical knowledge quickly
• Includes exercises with worked solutions to assist readers in grasping concepts found in the book
• Contains "in-depth" side bars throughout which pique the reader's curiosity

Fundamentals of Electric Power Engineering is an ideal refresher course for those involved in this interdisciplinary branch.

Introduction

1.1 The Scope of Electrical Engineering

It is universally agreed that Electrical Engineering is a branch of engineering that deals with the phenomena of electricity. Apart from this vague statement, however, there is no worldwide agreement on the actual scope of an electrical engineer. In particular, there are two main approaches:

• In some cases, electrical engineering is considered as encompassing those disciplines in which electrical quantities (voltages, currents) are used to transfer signals (e.g., in computers, radio and TV sets, etc.) and those in which electrical quantities are used to manage and transfer energy and power (electrical machines and lines, electrical household installations, etc.). This approach is, for instance, normally followed in North America.
• In other cases, electrical engineering is considered to be involved only when electrical quantities are used to transfer and convert energy and power. This approach is usually followed in Europe. This kind of electrical engineering is often called electric power engineering.

This book follows this second approach, hence its title. Generally speaking, the whole scope of Electric Power Engineering comprises everything needed to manage electric energy, from its generation to its final utilization.

The word “generation” might be a bit misleading since energy cannot, indeed, be generated: the term means production of electricity by conversion from other forms of energy. For instance, the electric alternators of large oil or gas power plants “generate” electricity by conversion from mechanical energy, in turn obtained by using other machines, like steam or gas turbines. Photovoltaic panels are another example of electricity generators: they produce electric energy through the conversion of solar radiation.

The final utilization of electricity very often involves another conversion; for example, the final energy form can be heat (in heaters or ovens) or mechanical energy (in industrial electric motors, in electric cars, etc.). There are cases, however, in which electric energy is used as such; the most significant example is for supplying computers or other electronic apparatuses.

Between generation and final utilization, electric energy can be transformed several times (for instance in power transformers, which raise the voltage while lowering the current and vice versa), and transferred for distances of up to hundreds or thousands of kilometres, by means of power lines.

Indeed, it will be seen in this book, especially in Part IV, that the more power to be transmitted, the higher the required voltage level. Therefore, the power system has low voltage (LV) parts (for instance, power in homes and offices is always LV), medium voltage (MV) parts (the alternators of large power plants generate po...
