摘　　要：随着大量新能源发电方式的并网以及超高压输电的普及,老旧变电站的接地网已经难以满足当今社会的安全需求,接地网的改造工作逐渐被提上日程。为了探究较为合理的接地网改造方式,基于IEEEstd80-2000建立相关数学模型,研究接地网占地面积、接地导体长度以及耦合对接地网基本性能参数的影响。根据实际工程数据,利用CDEGS软件建立相关的变电站接地网模型,并提出6种优化改造方式进行仿真研究。最后综合不同方案下的仿真结果,应对各种工程情况,得到总体性能较为优异的优化方案。With the grid connection of a large number of new energy generation methods and the popularity of ultra-high voltage transmission,the grounding network of the old substation finds it difficult to meet modern safety requirements.Thus the transformation of the grounding network has gradually been put on the agenda.To explore a more reasonable way of grounding network reconstruction,based on the IEEE std80-2000 to establish the relevant mathematical model,the influence of grounding network footprint,grounding conductor length and coupling on the basic performance parameters of the grounding network is studied.From actual engineering data,this paper uses CDEGS software to establish the relevant substation grounding network model,and puts forward six optimization modifications for simulation research.Finally,the simulation results under different schemes are integrated to cope with various engineering situations,and an optimization scheme with better overall performance is obtained.
