| Power Quality |
This book arises from different research projects on Power Quality Master classes on use and Electric Energy Quality taught at the University of Vigo. It isn´t only intended especially for electrical engineering students, but also teachers, technicians, public administrations, engineering enterprises, electricity consumers and all those who are willing to venture into this interesting and complex field of power quality and electrical energy systems. A lot of tabs, charts, figs & pics will make its reading easier.
In Chapter 1, the concept of quality of electric power is introduced and the three parameters to be analyzed: continuity of supply, quality of care and wave and relationship with the user. In Chapter 2 the rules on the quality of the energy question; Frequency variations are discussed in Chapter 3. Chapter 4 refers to the slow voltage variations and voltage fluctuations are studied in Chapter 5, their types and some of its consequences, such as flicker studied. In Chapter 6, voltage sags, surges and short interruptions are explained. In Chapter 7 voltage transients, surges, lightning, earthing and grounding techs are here analyzed. Chapter 8 discusses FACTS and HVDC equipment; Chapter 9 harmonics they are studied and, finally, in Chapter 10, voltage imbalances are treated.
It is a very complete and thorough treatment of the subject book and has a lot of tables, charts, figures and photographs; also it includes 30 pages with color photos and graphics to facilitate understanding of matter and makes it easier to read. Thank you Dr. Donsión
