摘　　要：针对目前我国电力系统的雷电探测定位系统采用基于VLF-LF雷电探测器接收雷电波地波及实际计算模型中采用真空雷电波波速的精度问题,研究和改正了雷电定位计算中由于地形因素引起的雷电波传播距离误差,并对雷电波传播速度进行了分析、比较和探讨。通过实例计算表明,提出的距离改正计算及雷电波波速的取值大大提高了雷电定位计算精度。At present, VLF-LF based Lightning signal detectors in the lightning detection system in electric power system of China mainly receive the ground wave, but it is the velocity of light in the vacuum that be adopted in ideal revolving model. According to the precision problem caused by the difference, the distance errors of lightning location revolving model changed by topography have been researched and corrected in the paper, and the propagation speed of lightning wave has been analyzed, compared and discussed. The positioning accuracy has been improved through the distance correction and the wave velocity selection, which were brought forward in this paper.
