摘　　要：研究架空配电线路感应雷过电压传播特性对有效指导配电网防雷具有重要意义。基于电磁场理论、Agrawal场线耦合方程建立雷电过电压数学模型,首先,分析影响感应雷过电压传播特性的主要因素;其次,利用ATP-EMTP仿真软件进行建模,发现不同雷电流幅值、大地电导率和雷击点位置对感应雷过电压波形特性影响较大,计算分析时应结合实际考虑;最后,通过在仿真模型中变电站侧加装避雷器发现可有效抑制感应雷过电压。It is of great significance to study the propagation characteristics of induced lightning of overhead distribution lines.This paper establishes a mathematical model for lightning overvoltage based on Electromagnetic Field Theory and Agrawal Field Line Coupling Equation.Firstly,it analyzes the main factors affecting the propagation characteristics of induced lightning overvoltage.Secondly,by using ATP-EMTP simulation software for modeling,it is found that different lightning current amplitude,ground conductivity and lightning strike point position greatly influence the induced lightning overvoltage waveform characteristics,therefore,practical considerations should be taken into account when calculating and analyzing.Finally,it is found that installing lightning arresters on the substation side in the simulation model can effectively suppress induced lightning overvoltage.
