摘要
文章基于ATP-EMTP软件,对110 kV输电线路在雷击过电压条件下的耐雷击性能进行了仿真分析,探究了接地电阻、雷电流波形及塔头空气间隙长度对输电线路反击耐雷水平和绕击耐雷水平的影响.仿真结果表明,这些因素对110 kV输电线路耐雷击性能有显著的影响,可为输电线路的设计与改进提供科学依据.
Abstract
The article is based on ATP-EMTP software to simulate and analyze the lightning resistance performance of 110 kV transmission lines under lightning overvoltage conditions,and explore the effects of grounding resistance,lightning current waveform,and tower air gap length on the lightning resistance level and winding lightning resistance level of transmission lines.The simulation results show that these factors have a significant impact on the lightning resistance performance of 110 kV transmission lines,which can provide scientific basis for the design and improvement of transmission lines.
