Power System Transients : Theory and Applications, Second Edition

Using formulas simple enough to be applied using a pocket calculator, this book presents analytical methods for transient analysis. It examines the theory of numerical simulation methods, such as the EMTP (circuits theory-based approach), and numerical electromagnetic analysis. The book highlights transients in clean or sustainable energy systems, such as smart grids and wind farms, since they require a different approach than overhead lines and cables. The simulation examples provided include: arcing horn flashover, a transient in a grounding electrode, and an induced voltage from a lightning channel.

This new edition covers a wide area from transients in power systems—including the basic theory, analytical calculations, EMTP simulations, computations by numerical electromagnetic analysis methods, and field test results—to electromagnetic disturbances in the field on EMC and control engineering. Not only does it show how a transient on a single-phase line can be explained from a physical viewpoint, but it then explains how it can be solved analytically by an electric circuit theory. Approximate formulas, which can be calculated by a pocket calculator, are presented so that a transient can be analytically evaluated by a simple hand calculation. Since a real power line is three-phase, this book includes a theory that deals with a multi-phase line for practical application. In addition, methods for tackling a real transient in a power system are introduced. This new edition contains three completely revised and updated chapters, as well as two new chapters on grounding and numerical methods.
