风力发电叶片裂缝监测技术综述

Review of Wind Turbine Blade Crack Monitoring Technology

能源是社会发展不可或缺的一部分,目前的能源消费结构仍是以化石能源为主,这进一步造成环境的恶化。因此,开发可再生风力能源成为保护环境的重要措施之一。叶片是风力发电机的重要组成部分,在正常的使用过程中叶片会出现破碎、砂眼、裂纹、蒙皮脱离等故障,甚至导致灾难性的倒塌,而且维护成本高。因此叶片裂缝监测技术具有非常重要的目的。文中介绍了国内外最新发展的几种叶片裂缝监测技术,分析其在实际应用中的优劣势,对其未来发展方向进行展望分析。

Energy is an integral part of social development and the current energy consumption structure is still domi⁃nated by fossil energy,which further contributes to environmental degradation.Therefore,the development of renew⁃able wind energy has become one of the important measures to protect the environment.The blade is an important part of wind turbine which,in case of normal operation period,will occur such faults as breakage,grit,crack,skin de⁃tachment and others,even lead to catastrophic collapse,and the maintenance cost is high.Therefore,blade crack monitoring technology has a very important purpose.In this paper,the latest development of several blade crack mon⁃itoring technologies both at home and abroad is introduced,its advantages and disadvantages in practical application is analyzed and its future development direction is prospected and analyzed.
