Electrical Power Systems

The book provides a clear, systematic and exhaustive exposition of the various dimensions of electrical power systems, both at basic and advanced levels, explained and illustrated through solved examples. Salient Features: Fundamentals of power systems, line constant calculations and performance of overhead lines Mechanical design of lines, HVDC lines, corona, insulators and insulated cables Voltage control, neutral grounding and transients in power systems Fault calculation, protective relays including digital relays and circuit breakers Power systems synchronous stability and voltage stability Insulation coordination and over voltage protection Modern topics like load flows, economic load dispatch, load frequency control and compensation in power system. State estimation in power systems, unit commitment, economic scheduling of hydrothermal plants and optimal power flows Zbus formulation, power transformers and synchronous machines as power system elements Large number of solved examples, practice problems and multiple choice questions. With all these features, this is an invaluable textbook for undergraduate electrical engineering students and practicing engineers.
