摘 要：風(fēng)機(jī)接地裝置作為雷電流泄放主要通道，同時(shí)兼工作接地、保護(hù)接地，其設(shè)計(jì)非常重要。但由于山區(qū)風(fēng)電場(chǎng)高土壤電阻率、風(fēng)機(jī)吊裝平臺(tái)面積有限、國(guó)內(nèi)外標(biāo)準(zhǔn)差異等特殊條件，使得山區(qū)風(fēng)電場(chǎng)接地設(shè)計(jì)較為困難，風(fēng)機(jī)接地網(wǎng)的造價(jià)也較高?；陲L(fēng)機(jī)接地網(wǎng)的功能，結(jié)合現(xiàn)有國(guó)內(nèi)外規(guī)范，給出了山區(qū)風(fēng)電場(chǎng)設(shè)計(jì)的主要原則及思路，供相關(guān)人員參考。

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
