Description

Principles of Power Engineering Analysis presents the basic tools required to understand the components in an electric power transmission system. Classroom-tested at Rensselaer Polytechnic Institute, this text is the only up-to-date one available that covers power system analysis at the graduate level.

The book explains from first principles the expressions that predict the performance of transmission systems and transformers. It then extends these concepts to balanced three-phase systems and unbalanced systems. The authors proceed to introduce symmetrical component analysis of transmission systems, three-phase transformers, and faulted systems. They also describe the design of untransposed transmission lines and discuss other analysis component systems, such as Clarke component networks.

Despite the tremendous changes that have occurred in the electrical industry over the last forty years, the need for a fundamental understanding of power system analysis has not changed. Suitable for a one-semester course, this book develops the necessary concepts in depth and illustrates the application of three-phase electric power transmission.

Reviews

"This graduate-level textbook provides power engineers with a new well—written book on how to analyze three-phase power networks. It combines all the essential formulas and methods necessary to achieve a basic power system into one source and will be an excellent book for a class on power engineering."
