光伏发电项目雷电易损性分析及雷电防护检测技术探究

Discussion on Lightning Protection Detection Technology of Distributed Photovoltaic Power Generation Project

光伏电站一般位于空旷的野外,极易遭受雷击,造成设备损坏、人员伤亡。因此,确保防雷装置完善至关重要。本文通过鹤壁晶科电力20MWp分布式光伏发电项目防雷检测,探究项目所在地年预计雷击次数,并进行阵列区接地电阻检测、等电位检测、SPD检查等。

Photovoltaic power plants are generally located in the open field,which are vulnerable to lightning,resulting in equipment damage and casualties.Therefore,it is very important to ensure the improvement of lightning protection devices.Through the lightning protection detection of Hebi Jingke 20MWp Distributed Photovoltaic Power Generation Project,this paper explored the annual estimated lightning strike times of the project location,and conducted grounding resistance detection,equipotential detection,SPD inspection in the array area.
