摘　　要：直流输电接地极设计目前基本依据以往的工程经验,由于其具有热力效应和电化效应,尚未形成统一的接地极设计标准。从极址的选择、系统分析、跨步电压的验算以及新型材料的应用进行了阐述,为特高压直流输电接地极设计提供参考。The grounding electrode of direct current transmission is generally designed based on the experience of previous engineering projects. The design standards of grounding electrodes are not uniform due to different thermal effect and electrochemical effect in different projects. Suggestions are herein provided for the design of grounding electrodes in UHVDC transmission line, including the location of electrodes, systematic analysis, recalculation of step voltages and the application of new materials.
