SMALL SIGNAL ANALYSIS OF INTEGRATED POWER SYSTEMS is an essential tool to discover possible low frequency oscillations which if undamped may lead to major power failures. This book covers various aspects of this phenomenon from modeling to techniques to control them. The book covers low frequency in the 1-3 Hz range as well as sub synchronous oscillations in the 10-50Hz range. Damping techniques for both types of oscillations are discussed as well as design of Power System stabilizers. Modeling and design of FACTS devices in included. Selective computation of Eigenvalue(s) in a large system is discussed. Wind power systems and its integration into the existing grid is discussed along with small signal analysis.

The year 2008 marks the 150th birth anniversary of Sir Jagadish Chandra Bose who, at a relatively young age, established himself among the ranks of European scientists during the heyday of colonial rule in India. He was one of those great Indian scientists who helped to introduce western science into India. A physicist, a plant electrophysiologist and one of the first few biophysicists in the world, Sir J C Bose was easily 60 years ahead of his time and much of his research that was ignored during his lifetime is now entering the mainstream. As the inventor of millimeter waves and their generation, transmission and reception, and the first to make a solid state diode, he was the first scientist who convincingly demonstrated that plants possess a nervous system of their own and "feel" pain. J C Bose later spent his life's savings to set up the Institute which carries his name in Calcutta and Darjeeling.This book covers Bose's life in colonial India, including the general patriotic environment that pervaded at the time and how he became one of the flag bearers of the Bengal Renaissance. It also examines the scientific achievements of this polymath and his contributions to physics and plant electrophysiology, while highlighting his philosophy of life.

Power system oscillations without a big disturbance occur spontaneously in a power system and if they are not damped out properly may lead to grid failure. In this book we examine the methodology to study this phenomenon from several angles. Modeling the system to investigate these oscillations is given top priority along with physical interpretation of the phenomenon. The book covers low frequency 1-3 Hz as well as sub synchronous oscillations in the 10-50 Hz range. The latter are called torsional oscillations. Design of Power system stabilizers as well as damping techniques for sub synchronous oscillations are discussed. Modeling and design of FACTS devices is included. The small signal analysis of multimachine systems along with the selective computation of Eigen value(s) of interest in a large system is presented.
