摘要
某山地光伏电站地处强雷阵雨多发地区,2016~2018年该电站大量光伏组件因遭受雷击而损坏。结合现场回路接线、设备参数及设计图纸资料进行分析,查明光伏组件大量损坏的原因为发电光伏方阵的防雷保护设计存在缺陷。对该电站光伏区防雷保护进行优化改造后,截至2019年8月该电站再未发生过光伏板损坏事件。
A mountainous region PV power station is located in a heavy thunderstorm prone area.A large number of photovoltaic modules in the station were damaged in lightning strike accidents from 2016 to 2018.Based on the analysis of the field circuit connections,equipment parameters and design drawings,it is found that the damage of the large number of photovoltaic modules is resulted from the defective design of the lightning protection system.After the optimal modification of the lightning protection system for the photovoltaic area in the station,the damage incidents of photovoltaic panels in the station hadn't happened as of August 2019.
