About the Book
Power System Analysis aims at providing a comprehensive coverage of the
curricula and will serve as a very useful textbook for electrical engineering students
at the undergraduate level. The book provides a thorough understanding of the
basic principles and techniques of power system analysis. Beginning with basic
concepts, the book gives an exhaustive coverage of transmission line parameters,
symmetrical and unsymmetrical fault analyses, power flow studies, power system
control, and stability analysis. With the inclusion of some advanced topics such
as state estimation, stability analysis, contingency analysis, and an introduction to
HVDC and FACTS, it would also serve the requirements of teachers and students
alike at the postgraduate level
Content and Coverage
The book comprises 15 chapters and three appendices. Each chapter in this book
commences with an overview, which briefly outlines the topics covered in the
chapter, and ends with numerous unsolved problems which help the readers to
assess their comprehension of the subject
matter studied in the chapter.
Chapter 1 in addition to tracing the history of the growth of the power sector
outlines its structure and its present state. Statistical data is included to
provide a perspective of the Indian power sector and its future plans for
meeting the load demand and making it more energy efficient. The concept
of deregulation of the power industry is also covered.
Chapter 2 covers the representation of power system elements suitable for
circuit analysis. A review of phasor notation, phase shift operator for threephase systems, and the power in single-phase and three-phase circuits is presented. It describes per unit representation of power systems and its
advantages in power system analysis.
Chapters 3 and 4 deal with the parameters of transmission lines and steady-state
performance and analysis of transmission lines, respectively. Chapter 3 outlines
the computation of the parameters of transmission lines. Chapter 4 covers
their simulation as short, medium, and long lines. Power handling capability
and reactive line compensation of lines are discussed. The phenomenon of
travelling waves on transmission lines is also included in the chapter.
Chapter 5 covers the representation of synchronous machines, transformers,
and loads in the steady state and transient analysis.
Chapter 6 introduces graph theory along with the commonly employed
terminology in the formulation of network matrices. Since network matrices
form the basis of power system analyses, the chapter comprehensively
covers the formulation of bus admittance and bus impedance matrices of a
power system network. The chapter also includes the formulation of nodal
equations, both in the admittance and impedance frames of reference, and
their solutions by direct and indirect methods. Sparsity techniques for storing
non-zero elements, network reduction, and optimal numbering schemes are
also covered in the chapter.
Chapter 7 on power flow studies of integrated power systems, under normal
operating conditions, provides a detailed description of the formulation
of power flow equations. Solutions of these power flow equations by the
well-accepted Gauss, Gauss-Seidel, and Newton-Raphson methods have
been presented in detail in this chapter. Fast decoupled method for solution
of power flow problems suitable for online studies has also been presented.
Chapter 8 deals with the maintenance of active power balance and control
of voltage magnitude and power frequency, within specified limits, when
a system is operating in the steady state. Beginning with the basic control
loop in a generator, the automatic voltage control (AVC) and load frequency
control (LFC) loops are described and their steady-state and dynamic
performances are outlined in detail. The LFC of a single control area is first
discussed and then extended to a two-area control system. Tie-line bias
control and its application to a two-area control system are also presented
in detail.
