某风电场升压站及场区防腐降阻及智能检测防雷接地网方案设计

【摘要】风电产业是可循环新能源产业，大力发展风电产业，对调整能源结构、推进能源生产和消费革命、促进生态文明建设具有重要意义。风电场多建于风资源较为丰富的山脊、丘陵、戈壁荒漠及沿海地带，特殊的地理环境导致生产及辅助设备极易遭受雷击的侵害。风场所处位置的土壤电阻率都较高、腐蚀性较强，接地网设计难度大，施工位置狭小，现有的接地材料运输困难，且接地网属于隐蔽工程，后期维护困难，修缮成本高。解决高电阻率、腐蚀性强地质环境下接地设计施工问题迫在眉睫。某风电项目位于内蒙古自治区库布齐沙漠边缘，建设容机为200MW，地质以风积细砂为主，电阻率较高，每个机位平均近似值300—600Ω.m，为黄土电阻率2-4倍，且具有一定腐蚀性，本设计方案通过对本项目接地布置、接地材料防腐性能及降阻性能的研究，能够有效提高风力发电系统的防雷、接地系统的安全性、可靠性、和经济性，为今后类似项目的施工提供技术参考和依据。
