This revised edition of Electrical Power System Essentials contains not only an accessible, broad and up-to-date overview of alternating current (AC) power systems, but also end-of-chapter exercises in every chapter, aiding readers in their understanding of the material introduced.
With an original approach the book covers the generation of electric energy from thermal power plants as from renewable energy sources and treats the incorporation of power electronic devices and FACTS. Throughout there are examples and case studies that back up the theory or techniques presented.
The authors set out information on mathematical modelling and equations in appendices rather than integrated in the main text. This unique approach distinguishes it from other text books on Electrical Power Systems and makes the resource highly accessible for undergraduate students and readers without a technical background directly related to power engineering.
After laying out the basics for a steady-state analysis of the three-phase power system, the book examines:
* generation, transmission, distribution, and utilization of electric energy
* wind energy, solar energy and hydro power
* power system protection and circuit breakers
* power system control and operation
* the organization of electricity markets and the changes currently taking place
* system blackouts
* future developments in power systems, HVDC connections and smart grids
The book is supplemented by a companion website from which teaching materials can be downloaded.
