风力发电场防雷接地技术

Wind Farms Lightning Protection and Grounding Technology

雷击是影响风电机组乃至整个风电场安全运行的重要因素,因此对风电场的防雷接地的研究具有重要的现实意义。结合实际风电场分析了风机雷击事故的破坏机理,针对实际风机接地电阻阻值要求和接地电阻的影响因素,对接地系统进行了研究,并对接地电阻进行了计算,提出了接地设计中应该注意的问题。

With the growing size of the wind turbine unit capacity of wind farms,wind farms in the safe operation of a growing concern.Lightning is an important factor in the impact of wind turbines and the whole wind farm safe operation.This paper analyzes the fan mechanism of lightning accidents,the factors for the fan requirements and grounding resistance of grounding resistance in the form of different grounding,grounding resistance calculation should be noted that the design of the ground.
