Power System Dynamics : Stability & Control

About the Book Modern power system tend to be very complex not only due to increasing demand for quality power, but also on account of extensive interconnections and increasing dependence on control for optimum utilization for existing resources. A good knowledge of system dynamics and control is essential for secure operation of the system. This book is intended to serve the needs of the student and practicing engineers. Basic concepts of stability and analysis, system model, small signal stability analysis, Sub synchronous Resonance (SSR) phenomenon — its analysis and counter measures, transient stability problems and direct methods of stability analysis are described in detail.
