摘要 针对江西地区沙地风电场土壤电阻率高的问题,对目前风电场普遍采用的深埋接地极、外引接地线、接地模块、单个风机接地网互连等接地方案在沙地风电场中的缺点进行了详细的分析。考虑接地工程对造价、施工周期的要求,在工程实践中进行积极探索和研究,推荐在沙地风电场接地工程中,采用钢接地棒、用洛阳铲做接地井、在风机场地下做三层地网等多种措施的联合实施方案。 Soil resistivity is high in jiangxi sand wind farm, Commonly used for the current wind farm buried grounding pole、 outer ground wire. the grounding module、, single fan grounding grid interconnection ground programs' shortcomings in the sandy wind farm has carried out a detailed analysis. The requirements of the ground works on the cost of the construction and cycle, Through active exploration and research in engineering practice, It is recommended that in the sandy wind farm grounding works, take the steel grounding rods. Luoyang shovel to do grounding wells, the wind airport underground three layer to network and variety of measures such as joint implementation program.
