Electrical Power System Essentials by Pieter Schavemaker and Lou van der Sluis

In the field of power system analysis, an extensive amount of high-quality literature is available. Most of these textbooks follow more or less the same line and cover the same topics. This book differs from existing materials because the (steady-state) modeling of the power system components is covered in appendices.

Therefore, the focus in the chapters itself is not on the modeling, but on the structure, functioning, and organization of the power system. The appendices contribute to the book by offering material that is not an integral part of the main text, but supports it, enhances it and as such is an integral part of the book. The following is a short summary of the contents of the chapters and the appendices.

Chapter 1 (Introduction to Power System Analysis) This first chapter describes the scope of the material, and is an introduction to the steady-state analysis of power systems. Questions like ‘why AC’, ‘why 50 or 60 Hz’, ‘why sinusoidallyshaped AC’, ‘why a three-phase system’ are addressed. The basics for a steady-state analysis of balanced three-phase power systems are outlined, such as: phasors, single-line diagrams, active power, reactive power, complex power, power factor, and per-unit normalization.

Chapter 2 (The Generation of Electric Energy) The conversion from a primary source of energyto electrical energyisthetopic ofChapter 2.The primary source of energy can be fossil fuels such as gas, oil and coal or uranium, but can come from renewable sources as well: wind energy, hydropower, solar power, geothermal power. In orderto understandthe nature of athermal power plant, which is still the main source of power in the system, the principals of thermodynamics are briefly discussed.

The final conversion from mechanical energyto electrical energyis achieved bythe synchronous machine. The coupling of the machine with the grid and the actual power injection is analyzed. Chapter 3 (The Transmission of Electric Energy) The transmission and distribution network is formed by the overhead lines, the underground cables, the transformers and the substations between the points of power injection and power consumption. Various substation concepts are presented, together with substation components and the protection installed.

The transformers, overhead transmission lines, and underground cables are then considered in more detail. The transformer design, possible phase shift, and specific properties due to the magnetic core are highlighted. As overhead transmission lines are the most visible part of the power system, they are discussed from the point of view of what may be seen and why it is like that. The underground cables are also considered, contrasting them with overhead transmission.
