| 摘 要： | 通常输电线路的雷电绕击采用EGM电气几何模型即击距法进行计算,但地面倾角和风速对线路绕击率有较大的影响。通过分析和计算,在地面倾角和风速情况下对EGM电气几何模型进行了参数修正。

| Abstract: | The lightning shielding failure of transmission line usually uses the EGM electrogeometric model to carry out the calculation,but the inclination angle of ground and the wind speed has the great influence on the rates of shielding failure.Through analysis and calculation,the parameters of EGM electrogeometric model are corrected based on inclination angle of ground and the wind speed. |
