In order to study the Hubei lightning locating system detection efficiency in 2015-2016, this paper adopts the method of mathematical statistics, compared and analyzed the distribution structure, detection efficiency, space-time distribution and lightning current characteristics between two lightning systems. The results show that the more sub-stations and the smaller the baseline distance are, the higher the detection efficiency is. The average number of cloud and ground lightning in 3D lightning locating system is 86.8% more than that in 2D system, and the proportion of positive ground lightning is slightly higher than that in 2D system. The positive and negative flashover of the 3D system are between 0-90kA, Positive current of 10-20kA and negative current of 20-30kA are the most. The positive and negative lightning in 2D system are between 10-100kA, the current has the highest percentage of 20-30kA and the lowest percentage of 10-20kA. The 3D system detection efficiency and lightning density distribution are better than 2D system. two sets are consistent in lightning time characteristics, geographical distribution and intensity distribution rules, which plays an important role in lightning disaster investigation, lightning monitoring and early warning and other business applications.
