Transient events are short-lived bursts of energy in a system resulting from a sudden change of the state. They can be caused by faults, switching events or sudden changes in generation and load. Given the need to expand HV cable grids and to interconnect national grids to increase grid flexibility, the effects of such transients need to be understood in order to maintain the security of power supply and power quality.

This book describes the three major power system transients and dynamics simulation tools based on a circuit-theory approach that are widely used all over the world (EMTP-ATP, EMTP-RV and EMTDC/PSCAD), together with other powerful simulation tools such as XTAP.
