  • 摘要: 提出了一种利用网格搜索法定位地球椭球面闪电位置的方法,在闪电可能发生的整个区域内寻找最适应解,通过采用多级网格搜索策略,计算结果将迅速收敛至最终解。分别用仿真数据和电网雷电定位系统实际电力线雷击事故点进行计算,证明了该方法的有效性和稳定性。
    Abstract: We proposed a novel algorithm for lightning location on oblate Earth surface. This grid-search based method is carried out overall coverage area of the network to find the most probable position of a flash. The solution of this method can rapidly approach ultimate location when multi-level gird search method is adopted. This meehod needs no initial solution, and in practice can be used to provide the initial solution for iterative algorithm. The validity and stability of the proposed method is confirmed by computer generated data and practical transmission-line lightning faults data of lightning location system for power industry.
