风力发电机组的防雷技术

Lightning Protection Technology of Wind Driven Generator Units

随着风力发电机组制造技术的成熟,以及海上风机制造技术的发展,风机多处在雷电多发区,风机遭受雷击是影响风电场安全持续运行和发挥风电经济效益的重要因素.结合目前风机防雷设计中常参照的国际电工委员会制定的标准IEC61400-24及相关技术,分析了并网运行的风力发电机组遭受雷击的特点,希望能在工程实践中针对风机的防雷有一定的参考作用.

With manufacturing technology of wind driven generator units coming to maturity and the development of that of maritime wind driven generator units,more and more wind driven generators locate in lighting flashing areas.When the generator is stroke by lighting,it will impact the sustainable safe operation of wind electric field and the role play of wind electricity benefits,which is a key factor.Based on the current lightning protection design standards of wind driven generators,IEC61400-24,set by the International Electrotechnical Commission as well as other technologies,the characteristics of winddriven generators struck by lightning which are in integrated operation were analyzed in hope that it can give some references to the engineering practice of the lightning protection for wind driven generators.
