山体对变电站接地网接地性能的影响研究

Analysis of the influence of mountain on characters of substation's grounding systems

提出了基于CDEGS仿真计算软件的分析模型和分析方法,设定变电站接地网在不同形状的山体上,分别对变电站接地网的接地电阻和跨步电压两大指标进行仿真计算,通过一系列的分析和对比,得出在各种情况下山体对变电站接地网接地性能的影响,并提出了恰当的工程建议。

An analyzing model and method using the CDEGS simulation software was introduced. By modeling the ground grids of substations on mountains with different shapes, the grounding resistance and step voltage, the most important parameters in substation grounding system, were simulated. With series of analysis, comparison and summarizing, it realized the analysis of influence from mountain on grounding system in substations on top of the mountain and summed up series of practicing and engineering suggestions.
