| 摘 要： | 采用ATP-EMTP软件搭建某实际线路模型,通过规程计算与仿真计算,对比分析3种雷击方式下的耐雷水平,研究哪种情况对线路的危害最大.针对雷击塔顶这种方式下,仿真分析其变量对耐雷水平的影响程度.并分析规程计算与仿真计算耐雷水平时产生误差的原因.认为:在对线路采取防雷措施时应特别考虑雷击塔顶这种情况并首先应将各基杆塔的接地...

| Abstract: | A model of real lines is built with ATP-EMTP,and through schedule calculation and simulation calculation,three lightning ways of withstand level are contrasted and analyzed,and it is studied that which is the most damaging situation to the line.And for the way of lightning stroke to tower top,the impact of variables on lightning withstand level is simulated and analyzed.Then the reason of inaccuracy during schedule calculation and simulation calculation is analyzed.It is considered that,that the way of ligh... |
