Analysis of Lightning Resistance Performance of 110 kV Transmission Line in Yantie Based on ATP-EMTP
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.
