Emulation and Analysis of Large Grounding System

大型接地系统的传统理论计算方法一直是比较复杂和抽象的,计算结果需要进一步处理,不够直观。本文借助CDEGS软件包根据实际情况建立地质模型和接地系统模型,对各种不同土壤分布状况,在发生单相接地故障时,计算出任何形状结构的接地系统的接地特性参数,CDEGS软件包对计算结果以直观的图形表示,给出安全性能评估报告,对不合格的情况提供改进建议和改造验算。

Traditional calculation of large grounding system is complex and abstract. Result is not intuitive enough and requires further process. With CDEGS package, this paper establishes soil models and grounding system models in actual situation. On the distribution of different soil, CDEGS package can calculate parameters of grounding system of any shape and structure when single-phase grounding fault occurs. CDEGS package can display results with intuitive graph,export safety evaluation report,provide recommendations for improvement as well as checking transformation if unsatisfactory situation exists in grounding grid.
