摘　　要：针对当前光伏发电系统容易遭受雷击,常用避雷针不能有效地防御雷击电磁脉冲的问题,通过分析雷电对光伏组件的危害,提出了采用避雷针和法拉第笼相结合的综合避雷措施来预防直击雷及其产生的雷击电磁脉冲,再通过等电位汇流排接入大地,使太阳能光伏组件免受雷电的危害,达到外部防雷系统的保护效果,从而使光伏系统安全、有效、规范的运行。For the problem that current photovoltaic power generation system is easy to lightning, and common lightning rod can not effectively defense lightning electromagnetic pulse, through analysis of the hazards of thunder to PV modules, a integrated lightning protection method combined Faraday cage and lightning rod was proposed to prevent direct lightning stroke and lightning electromagnetic pulse. Through a potential bus access to the earth, the solar photovoltaic modules could avoid the dangers of lightning stroke, achieving the protective effect of the external lightning protection system and leading to the safe, effective and standardized operation of photovoltaic systems.
