摘　　要：介绍了石化变电站接地系统工程设计的技术要求,通过案例分析接地网采用等间距和不等间距布置方案的2种设计方法,通过计算及EDSA软件建立模型仿真验证,得出较传统接地网设计所采用的等间距布置方案,接地网采用不等间距布置方案,接触电压差分布更均匀、接地导体利用率更高、更加节省投资、变电站接地设计更加优化的结论。The technical requirements of grounding systems for petrochemical substations are analyzed,and the design methods of equal and unequal spacing arrangement of grounding network are analyzed through case studies,which are verified by calculations and simulation of EDSA software model.It is concluded that,compared with the equal spacing arrangement of traditional grounding network,the unequal spacing arrangement of grounding network results in a more uniform distribution of contact voltage,higher utilization rate of grounding conductor,higher investment savings,and more optimized grounding design for substations.
