摘要
雷击事故在风电场中时有发生,为避免雷击事故中冲击电流对风力机的损害,风力机的防雷接地系统至关重要。文中结合大唐长清风电场一期工程采取的防雷接地系统方法,对风电场降防雷接地系统的施工工艺进行阐述,通过对施工工艺的分析及接地电阻阻值的测量,得出风场中各风机的接地电阻介于2.95-3.69Ω之间,说明采用多种降阻措施相结合的方法能有效的起到降低电阻的作用,同时也证明该风电场的防雷接地系统施工工艺是满足设计要求的。
Lightning in the wind farm when the accident occurred, in order to avoid the impact of current lightning accident damage to the wind turbine, wind turbine lightning protection grounding system is essential. In this paper, Datang Changqing wind farm project to the lightning protection and grounding systems approach, lightning ground down for wind farm construction process to elaborate the system, through the construction process of analysis and measurement of earth resistance, derived wind field ground resistance among 2.95Ωto 3. 69Ω, indicating that using a variety of resistance reduction method of combining measures can effectively play a role in reducing resistance, but also prove that the wind farm lightning protection grounding system construction process to meet requirements.
