Abstract
Based on the theory of attractive volume of lightning and the parameters of existing transmission lines of the Pearl River Delta region, the statistical method of single-span corridor is established in this paper. Selecting the lightning location data of the corridor area of transmission line in various terrain environments, the paper analyzes the probability distribution of lightning activity and lightning current amplitude before and after the erection of HV transmission lines, and makes calculation and simulation on the electrostatic fields of lightning leader and ground for the both cases based on finite element-charge simulation method to analyze the influence on ground flash from the HV transmission lines erected with statistical method of single-span corridor. The results show that the attractive effect from the transmission line is different in various terrain environments, and is greater in mountainous area.关键词
