The objectives of this book are to provide the student with a clear understanding of the basic principles of power systems and to stimulate them to study the subject at a more advanced level. It deliberately omits some of the more advanced concepts such as stability and load flow calculations.

The objectives of this book are to provide the student with a clear understanding of the basic principles of power systems and to stimulate them to study the subject at a more advanced level. It deliberately omits some of the more advanced concepts such as stability and load flow calculations. the basic concepts covered are three-phase systems, real, apparent and reactive power, the per-unit system, control of frequency and voltage and symmetrical fault calculations. It includes an explanation of the properties of major components of power system: alternator, overhead lines; underground cables; switchgear and the power transformer, development of simple equivalent circuits to represent the above components and a chapter on primary energy sources for electricity generation including energy storage and system management.
