摘要: 大型光伏发电站户外场的雷击及过电压侵入是光伏发电的重要威胁之一。采用仿真软件对光伏户外场的光伏电池阵列、汇流箱、逆变器和浪涌保护器(SPD)等设备进行建模仿真,研究不同雷电流幅值、不同接地电阻和不同雷击位置对光伏电池板的危害,以及过电压侵入波所产生的危害,并通过降低接地电阻和加装SPD改善光伏发电站户外场内设备的过电压,取得了良好的防雷效果。

Abstract: Lightning and over-voltage intrusion of the outdoor field of large-scale photovoltaic power generation stations is a major threat to photovoltaic power generation. In this paper, the ATP software is used for modeling simulation of the photovoltaic solar cell arrays, convergence boxes, inverters and surge protector devices(SPD) and other equipment. A study is made on the hazards of different lightning current amplitude, different grounding resistance and different lightning locations to the photovoltaic array and over-voltage invasion wave. Effective lightning protection results have been achieved through lowering the grounding resistance and adding the SPD to improve the over-voltage of the outdoor equipment of photovoltaic power generation stations.

Key words: photovoltaic power generation, ATP simulation, lightning over-voltage, invasion wave, SPD
