摘　　要：为确保光伏建筑发电系统的安全可靠运行,通过雷电易损性及雷电危害途径分析,探究光伏电池板雷击感应高压与典型雷电流之间的关系,得出雷电流的幅值越大、雷电流陡度越大、倾斜角越大、距离越近,雷击产生的感应高压危害也越严重。将三站大气电场联网和闪电与光伏建筑的距离组合,划分为4级预警,在不同的预警等级采取针对性的防御措施。通过计算雷击光伏建筑事故概率,提出等离子防雷构想,向光伏建筑周围输送与雷云同极性的电荷,降低电场感应,主动降低事故概率。In order to guarantee the safe and reliable operation of power generation system in photovoltaic building, based on the analysis of Lightning vulnerability and lightning harm way, the relationship between lightning induction high voltage of PV panels and the typical lightning current is explored, it is obtained that the lightning current is greater, lightning current steepness is greater, incline angle is greater, the closer, the more serious harm the lightning is. The three atmospheric electric field network is combined with distance from the lightning to photovoltaic building, it is divided into four warning level, specific defensive measures is adopted in the different warning levels. Through the calculation of accident probability for lightning photovoltaie building, the plasma lightning protection conception is proposed, that is deliver the same polarity charge thundercloud to the round of photovoltaic building,reduce the electric field induction, to reduce the lightning accident probability proactively.
