This paper deals with the comparison between measurements of lightning–induced voltages in distribution networks having complex topology, and numerical calculations. We make reference to a distribution system located in Colombia within a region with high ground-flash density. The numerical simulations are made by means of the LIOV-EMTP-code. The topological complexity of the experimental network requires the analysis of the influence of the network topology on the lightning-induced voltages. We discuss different methods that can be used to build equivalent LEMP-illuminated networks, with simpler topology than the original one. These methods are based on the appropriate placement of either surge impedances or non-illuminated lines.

Abstract

This paper deals with the comparison between measurements of lightning–induced voltages in distribution networks having complex topology, and numerical calculations. We make reference to a distribution system located in Colombia within a region with high ground-flash density. The numerical simulations are made by means of the LIOV-EMTP-code. The topological complexity of the experimental network requires the analysis of the influence of the network topology on the lightning-induced voltages. We discuss different methods that can be used to build equivalent LEMP-illuminated networks, with simpler topology than the original one. These methods are based on the appropriate placement of either surge impedances or non-illuminated lines.
