摘要

接地网对电力系统的安全稳定运行起着至关重要的作用。为了降低设备损坏和触电风险，需要对系统进行有效的地网设计。本文采用损耗接地的PEEC方法，对接地故障条件下接地网周围的电位分布进行了全面分析。讨论了接地结构、接地深度和土壤电导率的影响。研究了接地网结构与步进/转移电压的关系。这有利于接地系统的设计，保证电气安全。

Simulation of Ground Potential Distribution around Grounding Grids using a PEEC Method

The grounding grid plays a vital role in the safe and stable operation of an electrical system. To reduce the equipment damage and electric shock risks, an effective ground grid design for the system is necessary. In this paper, the PEEC method for the lossy ground is adopted to give a comprehensive analysis of the electric potential distribution around grounding grids under ground-fault conditions. The influence of the grounding structure, ground depth, and soil conductivity is discussed. The relationship between grounding grids structure and the step/transfer voltage are studied. This will benefit the grounding system design to guarantee electrical safety.
