摘　　要：电气装置接地分为系统接地、保护接地、雷电保护接地和防静电接地。不同用途和不同电压等级的电气设备的接地装置采取共用接地装置时,共用接地装置的接地电阻应符合其中最小值的要求。风力发电工程中,陆上风力发电机组(含升压箱变)的接地一般采用共用接地装置,国内现有风电场设计标准和风力发电机组设计标准中,对共用接地装置的阻值的要求各不相同。本文从风力发电机组(含升压箱变)防雷要求及接地要求出发,对陆上风力发电机组接地网的接地电阻进行分析研究,并以某风电场的风力发电机组的接地网设计为例,提出了陆上风力发电机组接地网的接地电阻值的计算方法及建议。The grounding of electrical equipment is divided into system grounding,protective grounding,lightning protection grounding and anti-static grounding.Different uses and different voltage levels of electrical equipment grounding device to take a common grounding device,the grounding resistance of the common grounding device should be consistent with the requirements of the minimum value.Wind power project,on-shore wind turbines(including booster box variable)grounding generally use common grounding device,the existing domestic wind farm design standards and wind turbine design standards,the common grounding device resistance requirements vary.In this paper,from the wind turbine(including booster box variable)lightning protection requirements and grounding requirements,onshore wind turbine grounding network grounding re-sistance analysis and research,and a wind farm wind turbine grounding network design as an example,puts for-ward the onshore wind turbine grounding network grounding resistance value of the calculation method and rec-ommendations.
