Simulated Calculation and Analysis of Lightning Overvoltage on Overhead High Voltage Power Transmission Line: I.Build-up of Model for Simulated Calculation of Lightning Overvoltage on Power Transmission Lines

为加强高压架空输电线路抵御雷害的能力,通过阐述我国110 kV及以上高压输电线路的基本情况,利用ATP-EMTP电磁暂态计算程序建立输电线路雷电过电压仿真计算模型,为进一步深入开展高压架空输电线路雷电过电压仿真计算分析提供依据。

For the purpose of uprating the ability of lightning protection for overhead high voltage power transmission lines, the paper takes accounts of the general conditions of transmission lines operated at and more than 110 kV, builds-up a simulated calculation model for lightning overvohage on the power transmission lines by means of a calculation program with ATP-EMTP electromagnetic transient, thus provides the accordance for further development about simulated calculation of lightning overvohage on the overhead high voltage power transmission lines.
