Abstract

A new procedure, based on a combined frequency- and time-domain approach, is presented for the transient analysis of dissipative power networks with nonlinear loads described by monotone characteristics. Special care is paid to the solution of the power network transient equations in case the line-sections are closed by protective devices such as varistors. Networks excited by transient internal sources or external electromagnetic fields are analysed. A simple procedure is implemented to include the simulation of coupling phenomena in the Electromagnetic Transient Program (EMTP). Applications are carried out to predict transient voltages and currents in medium-voltage power networks
