Abstract

Abstract: Aiming at the problem in mountainous terrain slope affect lightning protection performance of a tower, a new type of 220 kV split-level cross arm tower is designed to reduce the lighting trip-out rate of mountain transmission lines. Lightning protection performance of split-level cross arm tower under different slope conditions are analyzed to determine the feasibility of split-level cross arm tower in mountainous area. Multi-wave impedance model of the tower and equivalent circuit model of grounding electrode are established; the complete model for the tower is built based on PSCAD, and the rate of lightning back striking is calculated; modified electrical geometry model is established for solving the shielding failure rate of the new tower, and the calculation formulation is derived based on the geometric model; lightning trip-out rate of split-level cross arm tower under several slope conditions are analyzed and compared. Compared with the conventional tower, the new type split-level cross arm tower can improve the lightning withstand level of the tower effectively. Research results can provide references and basis to lightning protection in the design period and the reconstruction of transmission line in mountainous area.

Key words: transmission line, lightning protection, tower, split-level cross arm tower, modified electrical geometry model, lightning withstand level, lightning trip-out rate
