摘要
光伏发电系统是一种新兴的发电系统,我国还没有专门的光伏发电系统防雷设计规范。依据国际标准IEC62305-2对独立太阳能光伏发电系统进行雷击风险评估。采用计算雷击公众服务风险(R2)和经济损失风险(R4)的方法,通过分析R2的分险分量组成,有针对性地采取防直击雷和防雷击电磁脉冲的防护措施,通过分析R4说明上述防护措施的经济性。雷击风险评估可使防雷设计做到科学有效、经济合理。
A risk assessment of a photovoltaic stand-alone system is made according to the criteria IEC62305-2.Through calculating and analyzing the lightning stroke risk R2 and R4,the most effective protection measures(LPS and LPMS) for the object are selected according to the share of risk component R2 and the economical analysis of the measures(R4),so to reduce the risk to the tolerable level.
