Converter Transients Caused by Switching Type Surges on the DC Line

A complete model of a typical H.V.D.C. converter station suitable for fast transient studies is used to irivestigate the effect of the converter termination on switching-type surges coming from the dc-line. The surge transfer to the converter side of the dc-reactor and the surge distribution within the converter plint are also investigated. Finally, a dynamic model is used to calculate the surge transfer stresses during current extinction followirng a switching surge.
