Electrical Insulation Magazine - Mar/Apr 2019 - IEEE DEIS 5, testing and analysis of UHVDC systems, consists primarily of the effects of overvoltages on parts of a UHVDC system (i.e. connecting/disconnecting converter transformers, overvoltages on the AC side and DC side of the substation). Chapter 6, digital simulation, shows how to set up circuits to create overvoltage models in a power system.
