Abstract
Lightning activity poses a serious threat to the safe and stable operation of the power system, so it is of great significance to study the lightning protection technology deeply. To improve the lightning protection performance of power system, this paper proposes a comprehensive protection strategy based on multi-dimensional parameter optimization for the limitations of existing protection technology in complex environment. By combining the analysis of lightning current characteristics, insulation coordination optimization and the design of new lightning protection device, the protection model suitable for different voltage levels and geographical conditions is constructed. The study combines numerical simulation and field test to verify the effectiveness and feasibility of the proposed scheme. The results show that this strategy can significantly reduce the lightning trip rate and improve the lightning resistance level of transmission lines. In addition, this study introduces artificial intelligence algorithm for the first time to predict lightning activity, realizing the dynamic adjustment of protection measures, and provides a new idea for the intelligent lightning protection of power system.
