摘要
为研究雷电感应过电压特性,提出了一种基于MODELS语言并应用ATP-EMTP软件计算多导体传输线感应过电压的新方法。计算时考虑了大地损耗对垂直电场的影响,并且在计算过程中将线路本身等效为无损传输线。将实际计算的结果与火箭引雷实测数值以及其他模型计算结果进行了对比,验证了该方法的有效性。
In order to study the characteristics of lightning induced overvoltage, this paper proposes a new method based on MODELS and ATP-EMTP to calculate induced overvohage of multi-conductor transmission line. During the calculation, transmission line equaling to lossless transmission line, the influence of ground loss on radial electric field is taken into consideration. The method is proved effective by comparing the result of calculation and that of actual measurement of rocket lightning attracting and other models.
