Abstract
Lightning protection of large-scale photovoltaic power stations and grid-connected lines has gradually become a difficult problem with more and more large-scale photovoltaic power stations connected to the State Grid. In order to enable large photovoltaic power station to continue and stably operate, this paper targeted the grid-connected transmission line and designed the spiral multi-pair blowing device. The device leads the plasma arc to take on a spiral path, and the energy of plasma arc is sprayed out at the convection fracture of the unit and continuously consumed. Experiment results show that the device can extinguish lightning current in 2.1 ms and restore the transmission voltage to the normal level. The lightning protection device has the effectiveness of arc extinguishing, and it is beneficial to reduce lightning trip rate of transmission line of large-scale photovoltaic power stations. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.
大型光伏电站螺旋多对吹风机防雷研究
随着越来越多的大型光伏电站并网，大型光伏电站及并网线路的防雷已逐渐成为一个难题。为了使大型光伏电站能够持续稳定运行，本文针对并网输电线路设计了螺旋多对吹气装置。该装置引导等离子体电弧沿螺旋路径运动，等离子体电弧的能量在装置的对流断口喷出，并不断消耗。实验结果表明，该装置能在2.1 ms内熄灭雷击电流，并将传输电压恢复到正常水平。该防雷装置具有灭弧效果，有利于降低大型光伏电站输电线路的雷击跳闸率。©2024日本电气工程师协会和Wiley期刊有限责任公司。
