中文摘要	使用击距描述的电气几何模型广泛用于输电线路的雷电绕击分析。由于没有考虑导线工作电压的影响,导致其分析超高压及特高压输电线路的雷电绕击概率与实际运行数据存在一定的偏差。本文采用基于电磁场理论和模拟电荷法的雷电先导发展模型模拟向下发展的雷电先导的发展过程,分析了雷电击距与雷电流、导体高度和导体电压之间的关系,提出了考虑工作电压后水平导体雷电击距的修正方法。; The electrogeometric model (EGM) described with striking distance has been widely used in the shielding failure analysis of transmission line. However, as the operating voltage of the phase conductor is not considered in the EGM, the results of the shielding failure probability of ultra- and extrahigh voltage transmission lines from EGM departure usually from the operation ones. Simulating the developing process of downward lightning leader with the lightning leader developing model (LDM) based on the electromagnetic field theory and the charge simulation method (CSM), this paper analyzes the relationship among the lightning striking distance, the lightning current magnitude, the height of the horizontal conductor, and the voltage on the phase conductor, and proposes a method involved with the operating voltage to modify the lightning striking distance to horizontal conductor.; 国家自然科学基金重点项目(50737001)。
