摘要
国内外特高压输电线路运行经验表明:导致特高压输电线路跳闸事故的主要原因是雷击,并且随着电压等级提高,雷击导致跳闸的概率逐渐增大。本文以1000k V输电线路为研究对象,分别仿真并且分析了4种不同经典单回杆塔的绕击跳闸率.并且采用电磁暂态计算程序ATP-EMTP,对雷电波反击进行仿真,研究分析4种杆塔对雷电波在线路中传播的影响。
Ultrahigh-voltage transmission lines operating experience at home and abroad show that the main cause of the uhv transmission line tripping accidents is struck by lightning, with the higher voltage class, the probability of tripping accidents caused by lightning strike increased. This paper based on the 1000 k V transmission line as the research object, simulate and analyze detour lightning trip-out rate of four different classic Single tower back. Besides, Through the use of the electromagnetic transient calculation program ATP-EMTP and simulating of back striking, this paper Research and analysis ray propagation in a circuit of four towers.
