Power System : Analysis and Design
The objective of this book is to present methods of power system analysis and design, particularly with the aid of a personal computer, in sufficient depth to give the student the basic theory at the undergraduate level. The approach is designed to develop students’ thinking process, enabling them to reach a sound understanding of a broad range of topics related to power system engineering, while motivating their interest in the electrical power industry. Because the fundamental physical concepts underlie creative engineering and form the most valuable and permanent part of an engineering education, highlight physical concepts while giving due attention to mathematical techniques. Both theory and modeling are developed fromsimple beginnings so that they can be readily extended to new and complex situations.rnThis edition of the text has four new features, cause studies for 12 chapters describing present day, practical applications including ample coverage of the ongoing restructuring of the electric utility industry, the integration of PowerWorld Simulatir (PW Simulator), a user friendly power system analysis and simulation software package, with the text, six design projects including four at the end of chapter 6, one that begins at the end of chapter 6 and continues at the end of chapters 7 and 9, and one at the end of chapter 9, and updated as well as additional problems at the end of each chapter. Also, in response to a questionnaire sent to a number of power engineering educators. Symmetrical components covered in chapter 3 of the first two editions has been moved to chapter 8 in this edition, just before unsymmetrical faults. rnThe text is intended to be fully covered in a two semester or three quarter course offered to seniors and first year graduate students. The organization of chapters and individual sections is flexible enough to give the instructorssufficient latitude in choosing topics to cover, especially in a one semester 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.rnAs background for this course, it is assumed that students have had courses in electric network theory (including transient analysis) and ordinary differential 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.rnAfter an introduction to the history of electric power systems along with present and future trends, chapter 2 on fundamentals orients the students to the terminology and serve as a brief review. The chapter review phasor concepts, power, and single phase as well as three phase circuits.rnChapter 3 through 6 examine power transformers, trnasmission line parameters, steady state operation of transmission lines, and power flows including the Newton Raphson method. These chapters provide a basic understanding of power systems under balanced three phase steady state, normal operating conditions.rnChapters 7 through 10, which cover symmetrical faults, symmetrical components, unsymmetrical faults, and system protection, come under the general heading of power system short circuit protection. Chapter 11 is a self contained chapter on power system controls, including turbine generator controls, load frequency control, economic dispatch, and optimal power flow. rnThe last two chapters examine transient operation of transmission lines, including surge protection, and transient stability, which includes the swing equation, the equal area criterion, and multimachine stability. These self contained chapters come under the general heading of power system transients.rn
