摘 要：风机接地装置作为雷电流泄放主要通道，同时兼工作接地、保护接地，其设计非常重要。但由于山区风电场高土壤电阻率、风机吊装平台面积有限、国内外标准差异等特殊条件，使得山区风电场接地设计较为困难，风机接地网的造价也较高。基于风机接地网的功能，结合现有国内外规范，给出了山区风电场设计的主要原则及思路，供相关人员参考。
关键词：山区风电场；高土壤电阻率；风机接地网

Abstract: As the main channel of lightning flow, the wind turbine grounding device also has the functions of working grounding and safety grounding, so its design is very important. However, due to the special conditions such as high soil resistivity, limited area of wind turbine hoisting platform and the design standard difference at home and abroad, the design of wind farm grounding device in mountainous area was more difficult, and the cost of it was also higher. Based on the function of the wind turbine grounding device and combining with the existing domestic and foreign norms, this paper gave the main principles and ideas of wind turbine grounding device design in mountain areas to provide the references for the related personnel.
Key words: mountain wind farm; high soil resistivity; wind turbine grounding grid
