Electromagnetic Transients in Large HV Cable Networks

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 presents an overview of formulas to model transients in cable systems based on complete solutions of Maxwell's equations. It presents solutions to particularly model important high frequency phenomena. The impedance and admittance at a very low frequency for HVDC systems are investigated. In addition, the modeling methods of underground cables created in the Electromagnetic Transients Program (EMTP) are described. Moreover, the wave propagation characteristics of overhead lines and underground cables, and steady-state and transient behaviour of three-phase cables are further investigated in this book. Finally, transients in large interconnected HV cable networks in Denmark and the Netherlands are presented as case studies.

Electromagnetic Transients in Large HV Cable Networks enables researchers, HV system manufacturers and grid operators to model, simulate and analyse transient phenomena in large HV cable systems and to create solutions to counter and mitigate them.
