国内外工程变电站接地网设计的比较

Comparison of Design of Grounding Grid of Engineering Substation at Home and Abroad

基于大接地短路电流系统,对国内外工程变电站接地网设计进行了比较。国内工程以GB/T 50065—2011、DL/T 621—1997标准和相关电力工程电气设计手册为依据,国外工程以IEEE 80—2013标准为依据,介绍了接地网设计原则、计算方法及存在的主要问题。通过比较,为从事国内外工程变电站接地网设计的技术和管理人员提供参考。

Based on the large grounding short-circuit current system, the grounding grid design of domestic engineering substation and foreign engineering substation was compared.Based on GB/T 50065—2011 standard, DL/T 621—1997 standard and related electrical design manuals for power engineering for domestic project, and based on IEEE 80—2013 standard for foreign project, the design principle, calculation method and main problems of the grounding grid were introduced.Through the comparison, it can provide reference for the technical and management personnel engaged in the design of the grounding grid of engineering substation at home and abroad.
