山地风电场防雷接地技术研究与应用

Research and Application of Lightning Protection and Grounding Technology for Mountain Wind Farm

本文结合贵州桐梓白马山二期风电场防雷接地技术的研究与实践,针对山地地区土壤接地电阻率较高、施工环境有限等特点,总结出一套适合在山地地区防雷接地的施工方法,该方法能有效达到风电场防雷接地的相关技术标准,符合设计和规范的相关要求。白马山二期风电场全部机组防雷接地工作顺利完成,接地电阻测试一次检测合格,这一技术提高了现场防雷接地的施工质量,为承建工程的顺利完工起到关键作用,可为山地风力发电机组的防雷接地提供参考。

Combining the research and practice of lightning protection and grounding technology of the second phase wind farm in Baima Mountain,Tongzi,Guizhou,this paper summarizes a set of construction suitable for lightning protection and grounding in mountainous areas in view of the characteristics of high soil grounding resistivity and limited construction environment in mountainous areas Technical method,this method can effectively meet the relevant technical standards of lightning protection and grounding of wind farms,and meet the relevant requirements of design and specifications.The lightning protection and grounding work of all units of Baimashan Phase II wind farm is successfully completed in advance,and the grounding resistance test is qualified once.The results have improved the construction quality of on-site lightning protection and grounding work,played a key role in the successful completion of the construction project,and provided a reference for the lightning protection and grounding work of mountain wind turbines.
