摘要/Abstract

摘要： 介绍了变电站接地网优化设计基本方法、测试点选取及减小环境因素对测量结果影响的正确测量方法。以某110kV变电站为例，通过精确测量电位分布并结合数据进行分析，得出了较为准确的试验结果。通过对试验结果的分析，从改善电位分布的角度提出了几点有效改进接地网性能的措施。

关键词: 接地网优化设计, 电位分布测试, 三级法, 试验

Abstract: The basic method of optimized design of substation grounding grid was introduced, and the selection of measurement points and the correct measurement method, which can reduce the influence of environment factors on measurement result, were introduced too. Taking an 110kV substation as example, the potential distribution was measured accurately, the measurement data were analyzed, and the more accurate experiment results were obtained. Based on the result analysis, in order to improve the potential distribution, some measures were proposed to improve the performance of the grounding grid effectively.

Key words: optimized design of grounding grid, potential distribution measurement, three stage method, experiment
