Power System Analysis and Design – J. Duncan Glover, Mulukutla S. Sarma, Thomas Overbye – 5th Edition


This edition of Power System Analysis and Design has been adapted to incorporate the International System of Units (Le Syste`me International d’Unite´s or SI) throughout the book. Physical concepts are highlighted while also giving necessary attention to mathematical techniques. Both theory and modeling are developed from simple beginnings so that they can be readily extended to new and complex situations. The authors incorporate new tools and material to aid students with design issues and reflect recent trends in the field.

As background for this course, it is assumed that students have had courses in electric network theory (including transient analysis) and ordinary di¤erential equations and have been exposed to linear systems, matrix algebra, and computer programming. In addition, it would be helpful, but not necessary, to have had an electric machines course.

The organization of chapters and individual sections is flexible enough to give the instructor suficient latitude in choosing topics to cover, especially in a onesemester course. The text is supported by an ample number of worked examples covering most of the theoretical points raised. The many problems to be worked with a calculator as well as problems to be worked using a personal computer have been expanded in this edition.
