摘　　要：一般在沿海的滩涂或者在海面上建设沿海风电场的风电机组,一些风电机组的高度达到150 m,是雷击的主要目标,而风电机组中的叶片、机械结构以及轴承则是主要的雷击对象。雷电一般通过机械效应及热效应直接的方式损害风电机组,同时还会以电涌过电压效应及电磁感应效应间接的方式损害风电机组。因此,在制定沿海风电场雷电防护对策时,必须明确其危害的特点,还要评估雷电危害的风险,从而作为风电场雷电危害防护对策的依据,确保防护对策的切实可行。The wind turbines of coastal wind farms were generally built on the coastal mudflat or on the sea.Some wind turbines were 150m high,which was the main target of lightning strikes,while the blades,mechanical structures and bearings of wind turbines were the main targets of lightning strikes.Lightning generally damages wind turbines through direct mechanical and thermal effects,as well as indirect methods such as surge overvoltage effects and electromagnetic induction effects.Therefore,before formulating lightning protection measures for coastal wind farms,it was necessary to clarify the characteristics of their hazards and evaluate the risks of lightning hazards,in order to serve as the basis for lightning protection measures for wind farms and ensure their practicality and feasibility.
