摘 要：風機接地裝置作為雷電流泄放主要通道，同時兼工作接地、保護接地，其設計非常重要。但由于山區風電場高土壤電阻率、風機吊裝平臺面積有限、國內外標準差異等特殊條件，使得山區風電場接地設計較為困難，風機接地網的造價也較高。基于風機接地網的功能，結合現有國內外規范，給出了山區風電場設計的主要原則及思路，供相關人員參考。
關鍵詞：山區風電場；高土壤電阻率；風機接地網

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
