Part of the Power Systems book series (POWSYS)


Chapter 2 presents the basic properties of meshed transmission grids, concentrating especially on the reliability. The concepts of N − 1 criterion, adequacy, and security are presented. Different substation schemes are addressed.

The dynamics of the power systems after faults are briefly described. The PSA approach, used in this book, is presented, and the motivation to use it for reliability analyses for transmission systems is given. The state of the art in the field of the reliability assessments of power systems is described.
