Power System Transients

In this textbook, a variety of transient cases that have occurred or are possible to occur in power systems are discussed and analyzed. It starts by categorizing transients’ phenomena and specifying unfavorable situations in power systems raised by transients. It then moves on to different protective measures that have been implemented in the system to prevent disasters caused by those transients. It also explains different methodologies used to analyze transients in power systems.

This book discusses the modeling of components very extensively and provides analysis cases to assess a wide variety of transients, their possible effects on the system, and the types of protection commonly used for each case, along with methods fordesigning a sound protection system.

• Detailed models of system components along with power systems computer- aided design (PSCAD) implementation and analysis

• Comprehensive reference of transient cases in power systems along with design considerations and protective solutions

• The cases are not limited to classical transients such as lightning strikes and switching, but rather the book discusses transient cases that power system operators and engineers have to deal with, such as ferroresonance, in detail, accompanied by computer simulations

• A chapter on original materials related to transformer windings with induced traveling waves

Power System Transients: Modelling Simulation and Applications provides a comprehensive resource to mainly educate graduate students in the area of power system transients. It also serves as a reference for industry engineers challenged by transient problems in the system.
