| 摘 要： | 降低变电站的接地电阻、接触电压和跨步电压对保障变电站人员、设备安全特别重要。110kV鹿邑变电站因运行日久，地网腐蚀严重，已不能满足安全运行的要求。针对鹿邑变电站原有地网设计不规则的现状，运用CDEGS软件建立地网模型并仿真计算，提出两种地网改造方案。通过仿真分析结果得出敷设垂直接地极能有效地改善地网的接地性能。

| Abstract: | To reduce the substation grounding resistance, step and touch voltages is especially important for security of personnel, equipment of substation, l lOkV Luyi substation has been running for a long time, serious corrosion cannot meet the requirements of safety operation. In view of the current situation that Luyi substation grounding grid design is irregular,using CDEGS software to build network model and simulation calculation,this paper puts forward two kinds of network reconstruction scheme. The simulation results show the laying of vertical grounding can effec- tively improve grid grounding performance. |
