地面分布式光伏电站避雷针架设方案优化研究

Research on Optimization of Lightning Rod Erection Scheme for Ground Distributed Photovoltaic Power Station

针对偏远、空旷地区地面分布式光伏电站避雷针架设位置不合理,造成对电站的阴影遮挡,影响电站发电效率,或避雷针架设高度不够,造成保护范围缩小,不能对电器设备实现有效保护的问题,分析了避雷针全年阴影变化规律和避雷针高度与保护范围的关系,通过典型案例分析,探讨地面分布式光伏电站避雷针架设的优化方案。

The unreasonable position of lightning rods in ground distributed photovoltaic power stations in remote and open areas results in shading of power stations and affects power generation efficiency,or insufficient lightning rod height reduces protection range and prevents effective protection of electrical equipment.To solve these problems,the law of lightning rod shadow change throughout the year and the relationship between lightning rod height and protection range are discussed.Through typical case analysis,the optimum scheme of lightning rod installation for ground distributed photovoltaic power stations is discussed.
