风电叶片雷击防护的研究进展

Research Development of Lightning Strike Protection for Wind Turbine Blade

风力发电是一种清洁能源,近年来受到全球范围的关注。随着陆上风力发电场趋于饱和,风力发电逐渐向海上扩张。海上风电虽与陆上风电有所不同,但雷电袭击对于海陆风电力发电场来说,都是威胁其运行安全的严重问题。风电叶片作为风电机组的重要组成部件之一,其受雷击后会导致风机停运,带来严重的经济损失。叶片的雷击防护已引起人们的重视,成为风电领域和防雷领域的热点问题。本文阐述了风电叶片防雷系统的现状和问题,风电叶片雷击防护的研究进展,并结合复合材料雷电实验的研究成果,为海上风电叶片防雷系统的研究提供新思路和新方向。

Wind energy, as one of ecological resources, has attracted global attention in recent years. The onshore wind farms witness the flourish of the offshore ones. Although there are differences between onshore wind turbines and offshore ones, they are particularly vulnerable to lightning strokes. Wind turbine blade is an important component to wind power. Lightning strike of blade has a bad influence on wind turbine operation,which can result in severe economic loss. Therefore lightning strike protection of blade becomes a hot issue in the wind power and lightening strike protection field. This review paper presents problems of current blade lightning strike protection system, the technology and research development of blade lightning strike protection, and advanced materials for lightning strike protection technology, in order to provide new options for lightning strike protection of offshore wind turbine blade.
