Title: Electromagnetic transients in substations. Volume 2, Models, validations, and simulations: Final report

Abstract

High frequency transient electromagnetic interference (EMI) caused by faults. lightning, and switching on high voltage circuits in substations is characterized and quantified using a mobile four-channel transient EMI measurements system and validated traveling wave transient analysis models. More than 800 waveforms of high voltage switching transients and staged-faults were measured in air- and gas-insulated substations and used to validate a system of interrelated substation interference coupling models. The highest transient EMI levels expected from initial conditions of 2PU (Per Unit) disconnect switching, a 2PU circuit breaker fault. and a 10 kA lightning strike inside substations through 500 kV are calculated using the models. These initial conditions, believed to be nominally worst case for these three high voltage EMI sources, are defined as follows. For disconnect switching, the 2PU initial condition represents the maximum peak phase-to-ground voltage that can occur across a switch gap restriking at its greatest separation. An initial condition of 2PU peak phase-to-ground voltage can occur on an open and adjacent substation bus during switching from a remote location. A 10 kA lightning strike represents the maximum current expected to be attached directly to a 500 kV bus as a result of a shielding failure.
