基于CDEGS软件设计的下水库接地网改造

本文利用CDEGS软件,对天荒坪抽水蓄能电站水库区域的土壤及岩石等地质参数进行分析和拟合,并构建土壤的分层模型;然后通过对地网的网格大小、导体的疏密程度、接地网的面积、水平接地体的长度等因素进行经济比较和优化分析,设计出了符合安全标准的水下接地网。结果表明:水下接地网的设计满足设计要求,达到了改善接地网参数性能的目标。

Reconstruction of the Grounding Grid of the Water Reservoir Based on the Design of CDEGS Software

CDEGS software is used to analyze and fit the geological parameters of soil and rock in the reservoir area of tianhuangping pumped storage power station in this paper.The layered model of soil is constructed.Then through the economic comparison and optimization analysis of the factors such as the grid size of the grounding gird,the density of the conductor,the area of the grounding grid and the length of the horizontal grounding body,the underwater grounding grid meeting the safety standards is designed.The results show that the design of the underwater grounding grid meets the design requirements.The goal of improving the performance of the grounding grid parameters is achieved.
