"Power System Small Signal Stability Analysis and Control" presents a detailed analysis of the problem of severe outages due to the sustained growth of small signal oscillations in modern interconnected power systems. The ever-expanding nature of power systems and the rapid upgrade to smart grid technologies call for the implementation of robust and optimal controls. Power systems that are forced to operate close to their stability limit have resulted in the use of control devices by utility companies to improve the performance of the transmission system against commonly occurring power system disturbances.

This book demonstrates how the application of power system damping controllers such as Power System Stabilizers (PSSs) and Flexible Alternating Current Transmission System (FACTS) controllers namely Static Var Compensator (SVC) and Thyristor Controlled Series Compensator (TCSC) can guard against system disruptions. Power System Small Signal Stability Analysis and Control examines the signal stability problem, providing an overview and analysis of the concepts and of the controllers used to mitigate it. Detailed mathematical derivations, illustrated case studies, the application of soft computation techniques, designs of robust controllers, and end-of-chapter exercises make it a useful resource to researchers, practicing engineers, and post-graduates in electrical engineering.

Power System Small Signal Stability Analysis and Control, Second Edition analyzes severe outages due to the sustained growth of small signal oscillations in modern interconnected power systems. This fully revised edition addresses the continued expansion of power systems and the rapid upgrade to smart grid technologies that call for the implementation of robust and optimal controls. With a new chapter on MATLAB programs, this book describes how the application of power system damping controllers such as Power System Stabilizers and Flexible Alternating Current Transmission System controllers-namely Static Var Compensator and Thyristor Controlled Series Compensator -can guard against system disruptions. Detailed mathematical derivations, illustrated case studies, the application of soft computation techniques, designs of robust controllers, and end-of-chapter exercises make it a useful resource to researchers, practicing engineers, and post-graduates in electrical engineering.

This book is the byproduct of an attempt by the authors to investigate the feasibility of using Switched Reluctance Motors (SRMs) in light Electric Vehicles like auto-rickshaws, scooters etc. Two separate cases are taken up and the machine is fully designed and the performance fully simulated for both. The design was finally frozen at nominal ratings of 1kW, 3-phase, 48 V, 3000 rpm. The motor has run been without any closed loop reference. The closed loop design of the drive has however been done and the steady state and transient performance analysed using MATLAB 6.5. Though the design was done from very elementary design principles, the electromagnetic performance of the magnetic design has been verified using ANSYS 7.1. The motor was locally fabricated from scratch in the workshops both in and around the University. The power converter was fabricated in the laboratory. The closed loop control implementation on digital platform and testing of the entire drive is under progress. The book should help curious experimenters who are interested in developing whole set-ups from scratch through analytical principles and then making them work.
