基于CDEGS的雷达站地网设计与研究

Design and research of grounding grid in radar station based on CDEGS

针对雷达站地网的设计问题,以跨步电压和接触电压作为评判地网接地效能的重要指标,基于CDEGS软件,首先对雷达站土壤分层情况进行研究;然后,从接地网的疏密程度、均匀分布和是否安装接地棒这三个方面进行了仿真对比分析;最后,根据仿真结果,设计出符合安全标准的雷达站地网。

Aiming at the design of grounding grid of lightning protection system in radar station, the step voltage and the contact voltage are the important index to judge the grounding performance. Based on the CDEGS software, a research of the stratification of soil layer in the station is conducted firstly, and then, comparisons are made of the simulation results from three aspects, including the density of the grounding grid, the uniform distribution and the installation of grounding rod. Finally the ground network of the radar station in line with the safety standards is designed based on the si- mulation result.
