摘要
随着输电线路的大规模建设,在电网密集区域搭建同塔双回甚至多回的线路已成为一种趋势.在雷雨多发季节,同塔双回线路遭受雷击的概率显著增加,因此针对现有同塔双回线路进行耐雷性能分析并进行相应改造显得尤为迫切.针对广西省北海市盐铁110 kV同塔双回输电线进行基于电磁暂态计算程序(ATP-EMTP)的耐雷性能仿真,分析了多种因素对于线路耐雷水平的影响,并提出了相应的改进措施,这将有效提高盐铁110 kV线路的耐雷水平.
Abstract
With the large-scale construction of transmission lines,it has become a trend to build same-tower double-circuit or even multiple-circuit lines in the dense areas of power grids.In the season of thunderstorms,the probability of lightning strikes on the same-tower double-loop lines increases significantly,so it is especially urgent to analyze the lightning resistance performance of the existing same-tower double-loop lines and carry out the corresponding transformation.In this paper,for the 110 kV same-tower double-back transmission line of Yantie in Beihai City,Guangxi,we carry out lightning performance simulation based on ATP-EMTP,analyze the influence of many factors on the level of lightning resistance of the line,and put forward the corresponding improvement measures,which will effectively improve the level of lightning resistance of Yantie's 110 kV line.
