Application of PSCAD software to build the lightning simulation model for high voltage transmission line

Abstract

This paper uses PSCAD software to build the lightning simulation model for high voltage transmission line in two cases: the transmission line has a single lightning shielding wire (LSW) and the transmission line has double lightning shielding wires. Then proceed to simulate, calculate and analyze lightning withstand level when: lightning strikes on the top of the tower, lightning strikes over the lightning shielding wire and lightning strikes the overhead transmission line. Finally, the paper proposes some possible solutions to enhance the lightning protection performance of the transmission line.

Keywords: Lightning protection, lightning withstand level, lightning shielding wire, overhead transmission line.
