【摘要】：近年来,我国太阳能光伏电站规模发展迅速,地面光伏电站的防雷措施的完善与否,直接影响到电站的安全稳定运行。通过对地面光伏电站常见的直击雷危害分析,充分考虑光伏电站面积、投资等因素,利用雷暴日等气象数据分析和计算结果,通过对徐州新沂宋山24 MW光伏电站防直击雷方案的分析,结合经济性、合理性、可行性等等因素,合理的提出了地面光伏电站的直击雷防护方案:对于一般地区的地面光伏电站,可不在光伏阵列区域大量设置避雷针,直接利用组件边框、支架及其他金属材料的等电位连接,集合完善的接地系统,大多数情况下可以化解直击雷危害,起到防雷的作用。提出了光伏电站防直击雷方案及建议,为地面光伏电站防雷实施提供了可靠、有效的理论依据。
[Abstract]:In recent years, the scale of solar photovoltaic power plants in China has developed rapidly, and the perfection of lightning protection measures for surface photovoltaic power stations has a direct impact on the safe and stable operation of power stations. Through the analysis of the common direct strike lightning hazard of the ground photovoltaic power station, the area, investment and other factors of the photovoltaic power station are fully considered, and the results are analyzed and calculated by using the meteorological data such as thunderstorm day, etc. Through the analysis of direct lightning protection scheme of 24MW photovoltaic power station in Xinyi, Xuzhou, combined with economy, rationality, feasibility and other factors, The direct lightning protection scheme of the ground photovoltaic power station is put forward reasonably: for the ground photovoltaic power station in general area, lightning arresters can be set up in large quantities in the photovoltaic array area, and the equipotential connection of component frame, support and other metal materials can be directly used. Set perfect grounding system, in most cases can eliminate direct lightning hazards, play a lightning protection role. The scheme and suggestion of direct lightning protection for photovoltaic power station are put forward, which provides a reliable and effective theoretical basis for the implementation of lightning protection for surface photovoltaic power station.
