摘要
近几年新建的风电场大多数都选址在高山上,地形复杂,雷暴日较多,随之而来的是风力发电机组叶片受雷击的风险也进一步加大。叶片在风电机组中位置最高,是雷击的首要目标,是最容易受到雷击损伤的部件,因此叶片是整个风电机组防雷保护的重点。对此,该文就风力发电机组叶片雷击损伤的机理及防护措施进行简单的分析,并提出一些可供参考的意见与措施。
In recent years,most of the newly-built wind farms are located on high mountains,with complex terrain and more thunderstorm days,followed with the further increase of the risk of lightning stroke on the blades of wind turbines.The blade is the highest position in the wind turbine,which is the primary target of lightning stroke and the component most vulnerable to lightning damage.Therefore,the blade is the focus of lightning protection of the whole wind turbine.In this paper,the mechanism and protective measures of lightning damage to wind turbine blades are briefly analyzed,and some suggestions and measures for reference are proposed.
