Abstract:
With the large-scale construction of wind farms, more and more attention has been paid to the influence of meteorological disasters on the safety of wind farms. Meteorological disasters can damage the equipment in wind farms and reduce the efficiency of power generation. The meteorological disasters discussed in this paper mainly include: typhoon, thunderstorm and lightning, icing, rainstorm, sandstorm, high temperature, and other related disasters. We simply analyze the impact degree and classification of meteorological disasters on various divisions of wind farms (e.g., wind turbines, collectors, boosters, buildings, and roads). Based on the domestic and global literature, this paper comprehensively discusses the research on the in fluence of meteorological disasters on wind farms in recent decades. It is found that typhoon causes great mechanical damage to wind farm; Lightning could damage wind turbines and power grids; Icing causes equipment icing, mechanical failure and power generation loss; Rainstorm induces mountain torrents, which wash away buildings and roads in the wind farm and cause waterlogging and inundation of ground equipment; The main in fluence of sandstorm lies in the damage of wind and the impact of sand and dust on the blades and other sensitive equipment. High temperature causes the temperature of electrical equipment to rise, causing fire and explosion. Attention should be paid to secondary disasters such as typhoons, landslides and mudslides caused by rainstorms, fires in forests and grasslands caused by high temperature and drought.
