摘　　要：电力系统中性点接地方式是一个重要的综合性问题,对于电网正常运行具有重要意义。在当前的技术背景下,配网系统中性点接地方式主要包括大电流接地、小电流接地两种,并不存在统一的标准,不同接地方式适用于不同工作需求。文章通过对相关文献进行查阅,以含分布式电源(Distributed Generation,DG)的配网系统中性点接地为研究对象,设计含DG的配网系统中性点接地方式。为证实研究的有效性,结合仿真软件进行中性点接地方案仿真建模。最终发现,文章研究内容可以在架空线路、电缆线路2个场景中发挥出较为优越的技术效果,具有一定的实际应用价值。The neutral grounding method of the power system is an important comprehensive issue,which is of great significance for the normal operation of the power grid.In the current technological background,the neutral grounding methods of the distribution network system mainly include high current grounding and low current grounding,and there is no unified standard.Different grounding methods are suitable for different work needs.This article reviews relevant literature and takes the neutral point grounding of distribution network systems containing Distributed Generation(DG)as the research object,the neutral point grounding method of distribution network systems containing DG is designed.,To verify the effectiveness of this study,the author used simulation software to simulate and model the neutral point grounding scheme.Finally,it is found that the research content of this article can be applied to overhead lines The cable line has demonstrated superior technical effects in two scenarios and has certain practical application value.
