Fundamentals of Electric Power Engineering

The book "Fundamentals of Electric Power Engineering: From Electromagnetics to Power Systems" by Massimo Ceraolo and Davide Poli (and a similar title by Isaak D. Mayergoyz and Patrick McAvoy, focusing on electrical machines, power systems, and power electronics) offers a comprehensive and foundational treatment of electric power engineering. It systematically builds knowledge from the underlying principles of electromagnetism and circuit theory up to the analysis and components of modern electric power systems. This detailed summary will focus on the structure and content of the text by Ceraolo and Poli, which is explicitly structured "From Electromagnetics to Power Systems."

I. Foundational Principles: Electromagnetism and Circuits 🧲

The book begins by establishing the bedrock principles of electrical engineering, ensuring readers have a solid theoretical foundation before delving into complex power systems.

A. Preliminary Material and Electromagnetism

The initial chapters introduce the scope and organization of electric power engineering, along with essential conventions and International Standards (SI units). Crucially, the text rigorously reviews the Fundamental Laws of Electromagnetism. This section covers:

Vector Fields
Lorentz's Force Law
Gauss's Law for electric and magnetic fields
Ampère's Law and charge conservation
Faraday's Law of Induction, which is critical for understanding all rotating electrical machines and transformers.
The ultimate synthesis in Maxwell's Equations and the nature of electromagnetic waves.
Constitutive equations and continuous charge flow across conductors.

B. Electric Circuit Concept and Analysis

This section bridges the gap between field theory (electromagnetism) and lumped-parameter models (circuits). It introduces Kirchhoff's Current Law (KCL) based on charge conservation and Kirchhoff's Voltage Law (KVL) relating to circuit potentials. Key topics include:

Definitions of circuit elements.
DC Circuit Analysis Techniques such as nodal analysis, mesh analysis, series/parallel combinations, and fundamental network theorems like Thévenin’s Theorem.
Concepts of Power and Energy in DC circuits, including Joule’s Law.
The introduction of Energy Storage Elements: the Capacitor and the Inductor (including Magnetic Circuits).
AC Circuit Analysis, emphasizing sinusoidal functions and the use of Phasors for steady-state behavior analysis.
Detailed analysis of Power in AC Circuits, defining instantaneous, Active, Reactive, and Complex Powers—concepts that are central to power systems.

C. Three-Phase Systems

Moving toward realistic power transmission, the text transitions From Single-Phase to Three-Phase Systems. This part explains the fundamental advantages and analysis techniques for three-phase power, including:

Modelling three-phase lines.
The crucial technique of using a Single-Phase Equivalent Circuit for simplified analysis of balanced three-phase systems.
Calculating Power in Three-Phase Systems (both Wye and Delta configurations).

II. Electric Power Components and Conversion 🔌

With the fundamental laws and circuit analysis tools in place, the book progresses to the core components of the power grid.

A. Transformers and Magnetic Circuits

Transformers are the first major power component studied, due to their essential role in stepping voltage up for transmission and down for distribution. The coverage includes:

Detailed analysis of Magnetic Circuits and the operation of Single-Phase Transformers.
Extension to Three-Phase Transformers and their various connection types.
Understanding practical effects like Magnetic Hysteresis and Core Losses.
Open-Circuit and Short-Circuit Tests for parameter determination.

B. Power Electronic Devices and Converters

This section addresses the modern, increasingly vital role of Power Electronics in manipulating electrical energy flow for control, conditioning, and interfacing with new generation sources.

It details the operation and characteristics of key Power Electronic Devices such as Diodes, Thyristors, and Insulated-Gate Bipolar Transistors (IGBTs).
It covers the main types of Power Electronic Converters:
- Rectifiers (AC to DC conversion).
- DC-DC Converters (choppers).
- Inverters (DC to AC conversion, essential for solar, battery storage, and variable-speed drives).

III. Electrical Machines and Power System Analysis 💡

The final major segments cover the main rotating elements and the overall system analysis.

A. Electrical Machines and Drives

This part focuses on the principles of Electromechanical Conversion, applying electromagnetism to convert electrical energy into mechanical energy and vice versa.

Basic concepts of Electromechanics in Rotating Machines, including Faraday's Law and the generation of torque.
Detailed analysis of Direct Current (DC) Machines and their operation.
Comprehensive coverage of Alternating Current (AC) Machines:
- Synchronous Machines (used primarily for power generation).
- Induction Machines (the workhorse of industry for motor loads).
Principles of Electrical Drives, which combine electrical machines and power electronics for speed and torque control.

B. Power Systems

The culminating section integrates all components to study the vast and complex modern Electric Power System.

Structure of the Power System: An overview of generation, transmission, and distribution.
Power Flow Analysis: Methods like the Newton-Raphson method are introduced to determine steady-state voltages and power flows throughout the network.
Fault Analysis: The study of short-circuit conditions, including the use of Symmetrical Components to simplify the analysis of unbalanced three-phase faults.
Transient Stability: Analyzing the system's ability to maintain synchronism following large disturbances, often involving the Swing Equation.
Discussions on Power System Components, such as transmission lines and control mechanisms.
Introduction to New Generation Technologies, reflecting the ongoing evolution towards integrating renewable energy sources.

IV. Pedagogical Approach and Intended Audience 🎓

The book is characterized by its fundamental and in-depth approach, prioritizing a deep understanding of core concepts over a mere survey of applications. It is often cited as an ideal resource for:

Electrical Engineering Students seeking a cohesive foundation in power engineering.
Non-Electrical Engineers who need to quickly acquire knowledge of power system basics, including engineers in other fields (e.g., Mechanical, Civil) or professionals moving into the power sector.
Practicing engineers looking for a refresher course on fundamentals.

It includes valuable pedagogical features such as:

Exercises with worked solutions to aid concept retention.
Historical Notes (e.g., on Faraday, Maxwell, Kirchhoff, Tesla) to provide context.
"In-depth" sidebars to pique curiosity and explore advanced or related topics.

By structuring the material to naturally progress from the core physical laws of electromagnetism to the practical complexity of interconnected power systems, the book provides a robust, logically consistent, and comprehensive treatment of electric power engineering fundamentals.
